## What is Yotsu?

Yotsu is four logic puzzles a day. Not one more. A small daily ritual to sharpen your mind - with your morning coffee, or to unwind in the evening.

No ads. No tracking. No account to create. No endless feed pulling you back. You solve your four puzzles, and you're done for the day.

THE DAILY FOUR

- Shikaku — Split the grid into clean rectangles.
- Akari — Light up the whole grid by placing lights.
- Binairo — Balance the two symbols with three simple rules.
- Sudoku — Every number once per row, column, and region.

Every puzzle has a single, verified solution. Difficulty rises gently over time: easy to ease into, more challenging as you keep coming back.

BUILT FOR CALM

Yotsu is intentionally minimal. A clean interface, soft colors, zero distractions. Everything runs on your device — your progress, streaks, and stats never leave your phone.
