Our studio
Small studio, deliberate design
We believe puzzle games should be a break from the noise, not more of it. So we build calm, dark-themed, focus-first games — no timers shouting at you, no gacha, just satisfying logic.
Everything in SudokuZen is designed around one habit: a few minutes of deliberate thinking every day.
