100 Puzzles & Chaos: Frozen Castle tips covering every system in the game, from your first match-3 battle to Castle 30

Discussion

I put this together for anyone just starting out or anyone who feels like they're spinning their wheels in the mid-game. Puzzles & Chaos blends match-3 combat, RPG hero collecting, and a full kingdom-builder into one game, and there's a lot going on under the hood that the tutorial barely touches. This covers all of it.

Matching tiles doesn't just clear the board, it spawns soldiers that march forward and attack whatever's in their row. This means the position of your matches matters just as much as the color. If you match tiles on the left side but the enemy is on the right, those soldiers can straight up miss.
Your attacks can literally whiff if the enemy isn't standing in the row where your soldiers are marching. Enemies usually take up about two rows, and bosses cover around three. Always pay attention to where the enemy is positioned before you swipe.
If you don't have a hero of a certain element on your team, matching tiles of that element does zero damage. This is one of the biggest traps new players fall into. You'll match a perfect 5-chain of Ice tiles and wonder why nothing happened... it's because you had no Ice hero equipped.
The elemental counter system is straightforward but easy to forget in the heat of a fight. Fire beats Nature, Nature beats Ice, Ice beats Fire. Light and Dark just counter each other. Exploiting these matchups is usually the difference between barely clearing a stage and blowing through it.
Hitting an enemy with their own element deals neutral damage, so it's not wasted, but it's not efficient either. If you're stuck on a boss, restructure your team around the element that hard-counters them before you burn resources retrying.
Matching four tiles in a row creates a special explosive tile that clears a cross-shaped area when activated. This spawns a wave of extra soldiers and can set off chain reactions. Go out of your way to set these up because they're worth way more than two separate 3-matches.
Matching five tiles in a line creates a tile that clears every tile of the same color on the board. The chain reaction potential is massive. If you can line up a 5-match, it'll often do more total damage than your hero ultimates will.
Hero ultimate skills charge up from matching their corresponding element color. So if you have a Fire hero, every Fire tile match fills their rage gauge. Once it's full you can unleash their ultimate, which is usually a fight-changer.
Here's a weird mechanic that most people miss: your rage gauge actually charges faster when your matched attacks miss the enemy. Rage gain is doubled on a miss. This means sometimes it's strategically correct to match tiles where the enemy ISN'T, just to charge ultimates faster.
Enemies gain rage whenever your normal matched attacks hit them, so hitting them also helps charge their ultimates. This creates a genuine dilemma... you want to deal damage but you're also feeding their gauge. Time your bursts carefully and try to finish enemies before they pop off.
Enemies don't gain rage from your hero ultimate attacks though, only from normal matched-tile hits. This is why saving up ultimates and firing them together in a burst can be smarter than spreading damage out. You deal damage without charging their abilities.
Enemies also gain rage passively just from turns passing, so stalling doesn't work forever. Even if you avoid hitting them, they'll eventually get their ultimate. You need a defensive hero on your team to absorb the hit when it comes.
Always keep at least one tanky or support hero in your lineup for when enemy ultimates fire. A healer or defender can be the difference between surviving the big hit and wiping completely. Pure damage teams look good until you eat one enemy ult and it's over.
The game has five elements total: Fire, Ice, Nature, Light, and Dark. Try to cover at least three to four elements in your hero lineup so you're never in a situation where half the board is dead tiles producing nothing.
Building a team with good element coverage is more important early on than chasing one powerful hero. A balanced roster where every tile color does damage will carry you through the campaign way smoother than a stacked team with blind spots.
Economic heroes have a Book icon on their portrait, and military heroes show a sword, bow, or horse. This distinction matters a lot because economic heroes drive your castle progression and resource generation, while military heroes lead your armies. Prioritize economic heroes early.
Heroes in this game have two completely separate skill sets: one for match-3 combat and one for leading troops on the world map. A hero can be incredible in puzzle battles and mediocre for troop combat, or vice versa. Read both skill sets before you decide who to invest in.
Saya is one of the most important heroes to build early, even though her overall combat rating looks kinda mid. She increases troop capacity, which is a fundamental stat for basically everything in the game. She also gives construction speed bonuses. Her value is in progression, not flashy damage.
Don't chase max Saya upgrades through spending though. The base unlock from the first purchase already provides meaningful bonuses. Getting her to max tier costs way more money than the incremental benefit is worth for most players.
Chloe is a 3-star hero that reduces Stone and Iron building costs, and she's easy to overlook. She also has a small free speedup skill. Even at low levels her cost reduction starts saving you meaningful resources once you're past Castle 15 where Stone becomes the bottleneck.
William is a 2-star hero who reduces Food and Wood costs for buildings. Lower rarity means he's easier to upgrade. Assign him whenever you're building something that requires a lot of Food or Wood, even in the early game.
Elsa is a 4-star Purple hero sometimes offered in a cheap early pack, and she boosts construction speed. If you see her for a couple bucks early on and you're planning to push castles, she's worth picking up. Not mandatory, but a nice accelerator.
Your starter heroes, specifically Barron, Sophia, and Luke, are going to get replaced pretty quickly. Don't pour a ton of EXP potions or upgrade resources into them. You'll get better replacements from the story and early events.
Three economic heroes can be obtained from Hunting Monsters and clearing Monster Dens. This is one of the best free sources of useful heroes. Participate in monster hunts even if the rewards seem small because the hero fragments add up.
Odell is a 4-star Blue hero with an AoE attack who usually shows up during an early event. If you see the event pop, make finishing it a priority. AoE damage heroes make clearing campaign stages and Mesdi Portal content much smoother.
When summoning heroes, always do the 10x pull instead of singles. The 10x summon costs only 9 scrolls instead of 10, so you essentially get a free hero every time. There's no reason to ever pull one at a time.
Save your summon scrolls for banners featuring heroes you actually want rather than pulling on every banner that shows up. The gacha in this game is expensive and you'll regret blowing 50 scrolls on a banner full of D-tier heroes.
Most heroes in the game are actually terrible. Looking at the current tier lists, each element has maybe 2-3 viable heroes and then a long tail of D-rated ones. Avoid investing heavily in heroes that aren't pulling their weight in guides and community tier lists.
Tania is widely considered the best healer in the game and she pairs well with basically any carry hero. She's got solid ratings across PvE, PvP, and Boss content. If you pull her, build her.
Edith is a strong pick for Archer-focused teams because she reduces enemy ATK and DEF while also packing a stun. Great for climbing Arena and a reliable support pick even outside of Archer comps.
Your Citadel level is THE main progression metric in this game. Not your power rating, not your army size, not how pretty your base looks. Castle level gates everything... buildings, features, research, troops, and most event participation.
The Wall is almost always a prerequisite for the next Castle upgrade, so treat it like your co-priority. Upgrade your Castle, then immediately start your Wall. If you leave the Wall behind, you'll hit a bottleneck every single time.
Use the Castle upgrade requirement screen as your to-do list. It tells you exactly which buildings need to be at which level before you can upgrade the Castle again. If a building isn't on that list, it can wait.
Don't upgrade buildings just because they have a green arrow or look underleveled. Every build timer and resource batch you spend on something that isn't a Castle prerequisite is time you're not spending on actual progression. Stay focused.
Get a second builder as early as you can. Having two builders running simultaneously is one of the biggest time multipliers in the game. Use one for the Castle and the other for whatever prerequisite is needed for the next Castle level.
The way to use two builders efficiently: while your Castle is upgrading, have the second builder working on the next prerequisite. This way the moment your Castle finishes, the next required building is already ready and you can start the next Castle level immediately.
Your castle layout is fully customizable, and you can place buildings wherever you want. This is mostly a cosmetic/organization thing, but it's nice to group resource buildings together and military stuff together so you're not hunting for things.
Cosmetic event items aren't just decorations... they actually provide stat bonuses. Trees, shrubs, statues from events all give small boosts. Place them and don't sell them for pennies.
Prioritize resource buildings early on, but know that they'll be limited. For the first 4-5 castle levels you'll only have a single Lumberyard. Most of your resources come from the world map, not from base production.
World map gathering is your real resource income for most of the game. Your base production will never keep up with upgrade costs. Send out gathering marches constantly, and I mean constantly.
Send a gathering party out every single time you run out of energy or have idle troops. Empty marches are wasted progress. Even short gathering runs while you're actively playing add up massively over weeks.
Research Troop Load early so each march carries more resources back. This is one of those boring-sounding upgrades that makes a massive difference. More load per march means fewer marches needed and faster total income.
Train enough troops to fill every gathering march you can send out. You don't need a massive army early on, but you do need enough bodies to fill your march capacity. Untrained troop slots are empty wagons coming home with nothing.
Always prioritize the highest-level resource nodes you can safely reach on the world map. Higher-level nodes have more resources to collect and are worth the slightly longer march time.
Use alliance gathering boosts when farming Stone and Iron specifically. These are your bottleneck resources mid-to-late game, so any percentage boost on gathering them is worth popping.
Visit the Seer's Hut on the world map before you send out marches. The game explicitly tells you to do this and most people skip it. It gives you a head-start bonus on resource gathering that costs nothing.
Refresh your marches before going to sleep or stepping away from the game. If your troops come home and sit idle for 8 hours while you sleep, that's 8 hours of zero gathering. Send them out right before you log off.
Food and Wood are the early-game resources and they stay relatively easy to get throughout. Quests, events, rallies, and your base all supply them in decent amounts. They're important but rarely the real bottleneck.
Stone becomes the first real resource wall around Castle level 15. If you've been ignoring Stone nodes on the world map, you're going to hit a brick wall (pun intended) right around here. Start gathering Stone before you need it.
Iron becomes critical around Castle level 17 and beyond, and it's even harder to get than Stone. Once Iron unlocks, start gathering it aggressively. Don't wait until the Castle upgrade screen tells you you're short.
The single biggest mid-game mistake is waiting to gather a resource until you actually need it. By the time you're short on Stone or Iron for a Castle upgrade, you've already wasted days you could've been stockpiling. Plan one Castle level ahead at minimum.
Keep resource packs unopened in your inventory until the exact moment you need them. Opened resources sitting in your vault can be stolen in PvP raids. Sealed packs in your inventory are protected. This is a huge deal.
The Black Market unlocks at Citadel 6 and lets you convert Food and Wood into Stone or Iron. This is the best direct conversion option in the game. Use it when you're close to a Castle or Wall upgrade and just need a little more rare material.
The Sapphire Mine Store unlocks at Citadel 9 and sells Stone and Iron for Sapphires. This becomes one of your most efficient non-diamond sources of rare resources in the mid-to-late game. Don't sleep on it.
The Alliance Shop has gathering speed boosts that are incredibly efficient for long-term resource gain. The 50% gathering speed boost is subtle but over 20+ days of constant gathering it adds up to millions of extra resources. Buy these constantly.
Event Shops pop up during limited-time events and often sell Stone, Iron, and speedups. Always prioritize resources and speedups in event shops. Ignore cosmetics and other fluff unless you've already bought the important stuff.
The Diamond Shop should be your last resort for buying resources. It's the least efficient option. Only use it when you're close to a major upgrade and the time cost of gathering more would be worse than the Diamond cost.
Diamonds are the premium currency but you can earn a decent amount for free through events, quests, and milestones. The two best uses are buying VIP points and saving them for War Hall Scrolls later. Resist the urge to spend them on small convenience purchases early.
VIP 5 is a huge quality-of-life milestone because it unlocks auto-combat in the Mesdi Portal. This saves you an enormous amount of time on match-3 battles. If you're going to spend Diamonds on VIP, getting to level 5 is the target.
You can buy VIP points with Alliance Points instead of Diamonds. Ask your Alliance Leader or an R4 to stock the Alliance Shop with VIP points. This is a free path to VIP 5 that most people don't know about.
Join an alliance literally as soon as the game lets you, even if it's a random one. Alliance members send help to speed up your build timers, you get access to the Alliance Shop, and you can piggyback on stronger players' rallies for rewards. There's zero downside.
When picking an alliance, check its power level and activity. A dead alliance with 50 members who never log in is worse than a smaller active one. The benefits only work if people are actually playing and sending help.
If you can get into the #1 alliance on your server, do it. Being in the top alliance provides PvP protection on most servers since stronger players typically only attack people outside the top alliances.
Alliance members can send help that directly speeds up your building and research timers. Every time you start a build or research project, request help. The time reduction from 20+ alliance members helping adds up fast.
Participate in alliance rallies against high-level monsters even if you feel underpowered. The victory rewards come in chests that all participants get. You're riding the damage of stronger players and getting loot for it.
Alliance events, expeditions, and KVK (Kingdom vs Kingdom) events give extra resources and rewards. Participate in everything even if the event seems confusing at first. The rewards are usually worth the effort.
Alliances closer to the center of the world map often have better protection agreements and resource territory. If your alliance is in a good position, your gathering runs are safer and more efficient.
The Mesdi Portal unlocks around Chapter 4 and it's where most of your match-3 battles happen. This is almost as important as your main campaign progression because the battles here drop essential resources for castle development.
Work through the main story chapters first and foremost when you start playing. The story gives you a ton of free resources, hero unlocks, and teaches you mechanics. It's the best jumpstart in the game.
Completing specific Mesdi Portal stages can reward you with new heroes. Check what's available at your current progress level and push for stages that offer hero fragments or full hero unlocks.
Daily missions are the most reliable free source of Diamonds. Do them every day, no exceptions. Skipping dailies is like leaving money on the ground.
The beginner event runs for 7 days with an 8th day available for final redemptions. You can earn enough points to get a 5-star hero from this event. Don't let it expire without maximizing your points.
You need 800 points in the beginner event to get the 5-star reward hero. If you also hit certain Citadel level thresholds during the event, you'll get extra hero shards to upgrade them further. Push your Castle hard during this first week.
Your Talent tree has three branches: Economic, Military, and Balanced. Skip Balanced entirely and split your points between Economic and Military. The Balanced tree tries to do both and does neither well.
The "Rapid Build" ability in the Economic talent tree reduces building and research time by 20% for the next 5 minutes. The key trick: activate it BEFORE you start your biggest build or research project. The discount applies to the full timer of anything started during those 5 minutes, even if the build takes 3 days.
That Rapid Build timing trick is worth repeating because people mess it up: activate the ability first, THEN start the construction. If you start building and then activate Rapid Build, it does nothing for projects already in progress. It has a 24-hour cooldown so you want to use it on your longest timer.
In the Research Institute, prioritize the Economy tech tree. Construction Speed Up should be your first research target, followed by Gathering Speed Up and extra march slots. Military research can wait unless it's specifically required for a Castle prerequisite.
Construction Speed Up research has multiple levels, and every level stacks. Max this out as early as you can. The time savings compound over every single building you construct for the rest of the game.
Extra march slots or march queues from research mean more simultaneous gathering, which means more income. This is a top-tier research priority that people often overlook in favor of flashy military techs.
Infantry beats Archers, Archers beat Cavalry, Cavalry beats Infantry. That's the troop triangle for world map PvP and Alliance wars. Vehicles are weak against everything but strong against player defenses like walls.
Don't overtrain troops in the early game. You need enough to fill your gathering marches and survive the occasional PvP encounter, but dumping all your resources into massive armies is a progression trap. Those resources should go to Castle upgrades.
If your server has active PvP, use a Peace Shield whenever you're going to be offline for a long time. Losing troops, resources, and momentum during a Castle push is devastating. A shield costs way less than rebuilding after a raid.
Keep your exposed resources as low as possible. Unsealed resource packs in your inventory are safe, resources sitting in your vault are not. Open packs only when you're about to start a build and can burn through them immediately.
If a kill event starts on your server, shield up or go into full defense mode. Kill events incentivize stronger players to attack everyone. Don't be the easy target.
Redeem gift codes before you spend any Diamonds. Codes give free gems, speedups, and resources. There are usually several active codes at any given time... check the game's official channels and community forums for current ones. On iOS you might need to use the web redemption page.
The server resets daily at 00:00 UTC. Know what time that is in your timezone so you can plan your daily missions, event deadlines, and resource collection around it.
War Hall Scrolls are a required purchase with Diamonds to upgrade the War Hall, which becomes a prerequisite around Castle 22. There's no way around this cost. Save enough Diamonds specifically for this or you'll get stuck.
Using Diamonds to buy resources when you're just barely short of a major Castle upgrade is actually one of the best Diamond investments. If you're a million Stone short of Castle 22 and gathering it would take 4 extra days, buying it with Diamonds is a good trade. Time has value.
Using Diamonds for speedups should be your absolute last resort. Use all your gameplay-earned speedups first. Only spend gems on time when the resources are already gathered and the offer deadline is your real constraint.
Don't buy troop packs, skins, random hero pulls, or cosmetics if they don't directly advance your Castle level. Every purchase that doesn't move the Castle needle is a luxury purchase. Luxuries are fine if you have extra, but not if you're still climbing.
The Monthly or Weekly card is usually the best value-per-dollar purchase if you're planning to spend at all. The daily Diamond stipend adds up significantly over 30 days and helps smooth out resource gaps throughout your run.
Cheap $1-3 value packs that include speedups and resources can be great pickups if they directly help your next Castle push. These one-time packs often have the best diamond-per-dollar ratio in the game.
Castle levels 20-25 are achievable without spending money if you manage resources carefully and have a strong alliance. Going beyond that within a tight timeframe (like a 30-day offer window) usually requires some purchases or extremely high daily activity.
Most players should honestly reassess their goals around Castle 22-25. The resource requirements and build timers get exponentially harder after this point. Check whether the remaining rewards are worth the remaining grind before committing.
Late-game Castle upgrades can have base timers of 30-46 days before any reductions. That's for a single upgrade. Economic research, hero bonuses, alliance help, and speedups are the only things keeping these manageable.
The Dragon is a unique system where you raise and power up your own dragon. Claim your Dragon's Egg when it becomes available and invest in it steadily. Dragon power contributes to your overall strength in both PvE and PvP.
Match-3 combat is used in Adventure mode (the Mesdi Portal), Arena, Alliance expeditions, and Castle expeditions. Troop-based combat is a separate system used for PvP, Alliance wars, and world map fights. They're almost two different games sharing the same account.
Keep your economic heroes deployed for passive bonuses at all times, even when you're not actively playing. Their construction, gathering, and cost reduction perks work passively. There's no reason to ever leave those slots empty.
The game's community is pretty active in-game, especially in realm chat. If you're confused about something specific to your server... events, alliance politics, which resource nodes are contested... just ask. People are usually helpful.
Everything in this game is a marathon and not a sprint. A well-synergized team of solid heroes will outperform a random pile of S-tier units with no element coverage. A steady daily gathering habit beats a one-day Diamond binge. Consistency is the actual meta.

If anything here is off or if a recent patch changed something, drop it in the comments and it'll get corrected.
