What it does

Proper puzzles

Every puzzle is generated on your phone and checked to have exactly one solution. Easy, Medium, Hard and Expert, each with its own saved game and best time.

Play your way

Pencil notes, undo, erase and hints. Mistakes can show in red as you go or stay hidden until the end. Matching numbers light up when you tap one.

The floating world

Sixteen painted scenes of old Japan: Fuji in spring, a torii at sunset, a geisha in the Gion rain, a samurai at dawn. Four to start, and another every ten puzzles you solve. Pick your own colours for the numbers and grid.
