Gemdoku Support

Gemdoku is a gem logic puzzle: place exactly one gem in every row, column and colour region, and no two gems may touch — not even diagonally.

Tips

Tap a tile to mark an ✕; swipe to mark several. Double-tap to place a gem.
Out of hints or instant gems? They don't refill daily — your daily streak chest adds more every 7 days.
A level's progress is saved when you leave, so you can pick up where you were.
