An indie game studio building honest, handcrafted puzzle games for mobile and PC.
Small team, high standards. Every level we ship is verified by a solver before it reaches you.
Tap, pour, sort. When a tube fills up with one color… POP! A relaxing colour-sorting puzzle that starts gentle and ends up bending your brain.
What we're building next.
A first-person escape room where every lock has a logic — and every room has a story hiding behind it.
Our level generator creates and verifies new puzzles in seconds, so content keeps coming after launch.
Mad Keyhole is an independent game studio based in São Paulo, Brazil. We build puzzle games with one rule: never waste the player's time.
That means no impossible levels engineered to sell you a power-up, no fake hints, and no dark patterns. If our game says a puzzle can be solved, a solver has already proven it.
We care about the small things — the weight of a sound, the way a ball settles into a tube, whether someone with colour blindness can play at all.
