About

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.
