About this game

Rinmath is a daily rotational arithmetic puzzle.

Three concentric rings. You pick the spoke count: 2, 4, 6, or 8, and that's your daily tier. Drag any ring to rotate it. When every spoke's three stacked tiles add to the day's target, the rings flash a golden halo and you're done until tomorrow.

The same puzzle every player sees, every day, refreshed at UTC midnight. Solve it, share the emoji grid, come back tomorrow.

How it works
The day's target appears at the center. Drag any ring to rotate; each tile crossing snaps with a haptic click. As you rotate, the number outside each spoke updates live. When a sum equals the target, the spoke locks amber. All spokes lit means you've solved it.

Rinmath stores a few small files on your device: today's puzzle state, your lifetime solve log, and a widget rollup. Gameplay and history never leave the device.
