I built play10q — a daily 10-question trivia game with private leagues for friends

Hey r/SideProject 👋

Just launched play10q.com after a few weeks of building.

The idea: every day there's a 10-question quiz on a random general knowledge topic. ~2 minutes to play. You can create private leagues with friends to track streaks and compare scores.

I built it because I'm a generally curious person who loves trivia, and I wanted a game that brought those two together.

What I learned along the way:

- Writing 10 quality trivia questions every single day is way harder than I expected. Fairness, no ambiguity, one obviously-best answer instead of two-arguably-correct — it's a real craft.

- The share-result format matters way more than I'd have guessed. People don't recommend the game; they recommend their own score. The format determines whether it spreads.

- Daily-ritual products are a different design problem from one-and-done. Streaks, reminders, retention — the things that don't matter for a single play matter enormously when you want someone back tomorrow.

Now trying to figure out user acquisition (the eternal side-project problem). Would love feedback on:

- The product itself

- How you found similar daily-game projects

- Anything that confused you in the first 30 seconds
