New: challenge friends by link on your board, a new duel season every week from Quartz to Diamond and how rare your frame is.
Train your logic with Diadoku, a polished puzzle game built around one elegant challenge: place exactly one diamond in every row, column and colored region.
Think carefully: diamonds may not touch, not even diagonally. Every move matters, and three mistakes end the round.

• Challenge your friends: won a duel or the daily puzzle? Send the link. Your friend plays the same board and tries to beat your time.
• A new season every week: every Sunday the duel season starts again. Climb from Quartz to Diamond within a week, and the top 3 win crown frames.
• How rare is your frame? Tap an earned frame or avatar to see its rarity, from Rare to Mythic.
• The crowns now rise from bronze to gold, and the classic board wears the colors of the tiles.
• Fixed: after a duel win, the winner sometimes showed a frame and crown that were not earned yet.
• Many small improvements.
