Diadoku

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.

FEATURES • 1000 levels, each with its own board, that grow steadily more challenging • Boards from 8×8 to 10×10, with hard and very hard levels to test you • Duels: race another player on the same board, win trophies and climb from Quartz to Diamond • Monthly duel seasons with crown frames for the top 3 • A new Daily Challenge every day • Daily streaks with bonus hints on every 7th day • A weekly star league: collect stars, climb the leaderboard and win exclusive crown frames • Legends: the all-time star ranking • Your own profile with a gem avatar, frames and your name • Progress backed up in iCloud, so it comes back after a reinstall or on a new iPhone or iPad • A spoken, interactive tutorial • Light Mode and an elegant dark look • Helpful hints when you're stuck • Daily rewards that top up your hints • Track your best time, moves and three-star results • Share your results with friends • Optional reminders to keep your streak going • Suggest and vote on new features inside the app • Calm, premium visuals and satisfying feedback • Play the levels offline (duels and leagues need a connection)

Easy to learn, rewarding to master. Take a quiet break, sharpen your powers of deduction and find the right place for every diamond.
