Made to be solved
Every level has exactly one solution and can be cracked by reasoning. Luck is never the answer.
We design small, carefully built games for your phone: clever to play, honest about what they do, and fully playable offline.
One game, made properly, before the next one.
A logic puzzle where every piece carries a number and an arrow. Fill the board without breaking a single rule — no guessing, no rotating, one action per move.

Four principles we apply to every game we make.
Every level has exactly one solution and can be cracked by reasoning. Luck is never the answer.
Helps are off until you ask for them. What the game measures and what ads do is explained in plain words.
Your progress lives on your phone. No account, no sign-up, and the whole campaign plays without a connection.
Anonymous statistics only by default. Anything more is your choice, and it is as easy to decline as to accept.
Behind a simple-looking puzzle there is a real rules engine, a solver and a test suite. That is what lets us promise one solution per level.
Game rules, level generation and a solver live in a tested C# core, separate from the engine that draws the screen.
Boards are generated sudoku-style, then a solver proves the solution is unique before a level ships.
A weighted formula rates every puzzle, tuned on generated boards and then on how players actually fare.
14 languages, a colour-blind palette, large text and a reduce-motion option from day one.
