Kocko: Block Puzzle

A fresh daily challenge every day. Fit blocks, clear rows, columns and 3×3 boxes, and chase the leaderboard.

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 score (par) on every level — clear the board in as few moves 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. Pick a nickname and compare your score on the daily leaderboard. • 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 ads; an option to remove ads for good is available right in the app.
