Kocko: Block Puzzle

Kocko is a block puzzle on a 9×9 grid. Place pieces to clear full rows, columns and 3×3 boxes. Clear the board and find room for the next block.

Drag blocks of different shapes from your tray onto the board, complete full groups and watch them clear. There is no timer: play at your own pace.

WHAT'S INSIDE
• 113 levels across 9 worlds of rising difficulty. Every level has a verified solution.
• A campaign with a clear goal: use every piece in the given sequence and leave the board completely empty after the last piece.
• Three stars for finishing within the target number of clears. Each cleared row, column and 3×3 box counts separately, even when you clear several in one move. Stars are based on clears, rather than the number of moves.
• An endless daily challenge. The same sequence of pieces is generated for the same local calendar date. When none of the available pieces fits, you can end the run or get new pieces and keep playing.
• Personal daily results: a history of played days, best and last results, completed attempt counts and a personal best across saved days.
• Daily streaks to keep your run going.

In version 1.0.7, the entire game works without an internet connection. Progress, settings and daily results stay on your device. If persistent storage is unavailable, the game warns that results will last only until you close it.
