Rinmath

Spin three rings. Hit one target. Solve today’s puzzle.

Rinmath is a quiet daily arithmetic puzzle built around three concentric number rings. Drag a ring to rotate it. Each spoke combines one tile from every ring; align all of them with the center target to finish the board.

CHOOSE YOUR DAILY

Pick 2, 4, 6, or 8 spokes and choose addition or multiplication. Every combination has a deterministic puzzle for the day, refreshed at midnight UTC, so players using the same settings receive the same challenge.

SOLVE WITH INTENT

• Live spoke totals update as you rotate.

• Matching spokes lock with an amber glow.

• Exact par is the minimum number of ring drags needed to solve the board.

• Solve Coach can reveal the best next move when you are stuck.

• Difficulty follows the weekly rhythm from Easy through Expert.

BUILD A STREAK

• An eight-week History calendar keeps solved days visible.

• Lifetime Stats track solves, streaks, best times, average moves, and par rate.

• Free Play lets you practice without changing the daily streak.
