Duotile

A tiny grid. A clear mind. Endless puzzles.

Duotile is a minimalist logic game with two puzzle types:

• Two Colours – fill the grid with coral and teal. Never three in a row, equal counts in every line, no two lines alike.

• Mosaic – numbers tell how many cells around them are filled. Reveal the hidden picture.

Every puzzle is generated on the spot by a solver that only uses logic. That means exactly one solution and no guessing, ever.

Features

• Endless puzzles in sizes from 6×6 to 12×12, three difficulties each

• A new daily puzzle for both types – with online leaderboards (today, this week, all time)

• Hints that explain why a cell must be what it is – the lessons teach every technique

• Points, levels and 14 achievements

• Undo/redo, check, drag-to-paint, colour-blind symbols, light and dark theme

• Mouse, touch, keyboard and gamepad

• English and German

• Works offline, no account, no ads, no tracking

Controls: tap/click to change a cell (right-click goes back), drag to paint. Keys: arrows, 1/2/0, H hint, Z undo.
