## What is Hueku?

Hueku is sudoku — but with colors.

Instead of numbers 1 through 9, you place 9 hand-picked colors on the grid. Same rules you already know: every row, column, and 3x3 box must contain all 9 colors exactly once. New way to see it.


WHY COLORS?

Numbers train your logical brain. Colors train your visual brain. After a few puzzles, you stop thinking "what's missing" and start seeing it. It's calmer, faster, and feels nothing like the math homework version.


4 DIFFICULTIES

- EASY: gentle introduction, 5 lives, around 40 colors pre-filled
- MEDIUM: the daily-coffee level, 4 lives
- HARD: for when easy feels like reading, 3 lives
- EXPERT: sparse boards that take real concentration, 3 lives

Every puzzle has exactly one solution. Generated locally on your device. No internet required.
