## Description

One gem per row, column and colour - no two touching. Hundreds of levels, a shared daily challenge and a weekly leaderboard.

Gemdoku is a calm, clever logic puzzle. Place exactly one gem in every row, every column and every colour region - and no two gems may touch, not even diagonally. Every level has a single solution you can reach by pure deduction: no guessing, ever.

HOW IT PLAYS
- Tap a tile to mark an X, swipe to mark several, double-tap to place a gem.
- Boards grow from 4x4 to 10x10 as you progress, with a HARD level every 10 levels.
- Hints explain the exact deduction, so you learn the techniques as you go.
- Three lives per level. Lose them all and you can retry any time.

EVERY DAY
- A Daily Challenge shared by every player - see how many you beat.
- A daily streak with a reward chest every 7 days.
- A weekly leaderboard of real players.

MADE FOR SHORT BREAKS
- Levels save mid-way, so you can pick up where you left off.
- Sound, voice and haptics you can turn off.
- No account needed.

Gemdoku is a fresh take on the Queens / Star Battle family of puzzles, built for one-handed play.
