Chain Sudoku

First Fold

About this game

This is not the sudoku you're used to.

Place numbers, build a chain of correct moves, and push your multiplier to ×5. One mistake and the chain breaks. Before every puzzle, draft a modifier: faster combos, an ice shield, diagonal focus. No two runs play the same.

- 6×6 grid — built for one-handed play
- Roguelite modifiers: 12 cards, many strategies
- Runs last 3–6 minutes
- Daily challenge with a shared leaderboard
- Themes, symbol sets, and effects to make it yours
- No energy, no wait timers — play as much as you want
