Duol
Dual puzzle · Android
One swipe moves two orbs, the red one and the blue one. Land each in the ring of its own colour. Walls stop them, pits swallow them, and if they crash into each other, they burst.
We make calm puzzle games for your phone. Each one has a single rule, a look of its own, and an aha waiting in every level.

Fill-in puzzle · Android
A crossword where every answer is a number, and the numbers are already in your hand. Place each one where it fits and watch the crossings fill in. No arithmetic, just logic.
How we make them
Each game rests on one rule you learn in a minute, then grows into puzzles that take real thought.
Soft 3D orbs that roll and burst, or pencil lines on paper: every game gets a look made just for it.
