Tessellate Nine

A tiling puzzle built from nine primitives — three triangles, three rhombi, two arcs and a square — that combine into boards you fill without overlap. There is no fail state and no clock. A board stays on your screen until you solve it or swap it out.

The generator produces boards with exactly one solution and a measured difficulty score, so the 620 hand-picked puzzles in the game climb at a rate we could actually tune. We ship a new set of twelve on the first of each month.

It is also our accessibility work. Every shape is distinguishable by silhouette alone, the palette passes contrast at the AA threshold in both themes, and the whole game is playable with TalkBack describing the board state.
