Play at your pace — Trivial, Easy, Medium, Hard, or Extreme. Each step up clears more of the grid for a tougher solve.

Always Solvable

Dress the grid your way. Pick from 23 hand-tuned palettes — from classic and vivid rainbows to soft pastels and rich gradients — with a live preview of each.

Ranks & Best Times

Every solved puzzle earns points and climbs your rank from Novice all the way to Yoda. Your fastest time is tracked for each difficulty.
