Could you share some ideas for mini-games I can put in a fair and challenge my players instead of their dice rolls?

So. My players will be participating in a town fair tonight, and I'd like some ideas for minigames I can put in there. I'd like things that would not rely on Dice Rolls, if possible. What I have now:

1 - A "decode this message" puzzle I have created, they'll have the whole session to deal with this while other things happen.

2 - A "Mastermind" (I think it is called that) game, There are 4 bottles of different colors, and they have 5 chances to order these bottles in a random order previously set. (Basically this game)

I'm not totally oposed to dice games. I have one little gambling game based on dices that they can also be part of, and a big lottery that they can buy tickets with 25 GP each. At the end of the fair, I'll roll a d100 and, if any of their numbers is sort, they'll get a +1 Weapon or Armor. (They're all level 5).

Anyway. If you guys have any other ideas, please, let me know!
Thank you for reading this!
