Kocko: Block Puzzle

Fit blocks. Clear the board. Chase your best score. Kocko is a calm, quietly addictive block-fitting puzzle on a 9×9 grid. Drag blocks of different shapes from your tray onto the board, complete full rows, columns, and 3×3 boxes — and watch the board clear with a satisfying snap. No timer, no pressure. Just you, the grid, and the next block deciding where it fits best. WHAT'S INSIDE: • 113 levels across 9 worlds — every level is solver-verified, so you know it can always be completed. • A target (par) on every level — finish the level in as few clears as possible to earn all three stars. • Daily challenge — an endless mode with the same set of blocks for every player on a given day. The leaderboard is off by default and a parent turns it on; you choose a nickname from preset words and publish each result only after confirming. • Daily streaks — come back every day and build your run. • Nine worlds of rising difficulty — from your first simple blocks to dense, multi-layered puzzles. • Relaxed play, no pressure — play at your own pace, anytime, anywhere. Kocko is free to play, with no ads and no in-app purchases. No account, no sign-up — just fit blocks and clear the board.
