How it works

Pick a mode: 3, 4, or 5–digit. The materials, target range, and timer scale with the mode. Cycle with D.
Materials are drawn in order, each tumbling quickly. Press space to lock.
Once the last material locks, a target is computed and rolled — always one your materials can solve.
Compose an expression from the materials and basic arithmetic. Allowed operators: + − × ÷ ( ) — every intermediate result must be an integer, no fractions.
Use any subset of the materials, each at most once.
Hit enter to submit, or let the clock run out.
Practice: the running sum is shown while you type — for learning the feel. Practice games don't count toward your stats. Toggle with P.

Seed

A seed is a phrase that pins the game — same seed + same round = same materials and target. Two players sharing a seed race on identical boards. Seeded games don't count toward your stats.
