CubiClear: Slide Block Puzzle

A box is packed solid with 3D block puzzle pieces. Every piece has exactly one way out with an arrow showing its direction. Slide a piece free only if the path is clear all the way to the edge. Clear every piece and the box is solved.

Simple to learn, deceptively hard to solve at larger sizes.

CAMPAIGN
Work through 13 box sizes, from a compact 3x3x3 up to a dense 7x7x7, each with an easy and a hard tier. Every size unlocks from the start, so jump to whatever challenge you're in the mood for: thousands of hand-picked levels in total.

DAILY CHALLENGE
One puzzle a day, identical for every player worldwide. Race the clock, climb the global leaderboard, and build a streak. Miss a day and it resets, so keep coming back.

FREE PLAY
Generate a fresh box on demand at any size and difficulty. Endless practice with no limit to play.

PLAY YOUR WAY
- Rotate the box to see every angle: no piece stays hidden for long
- Undo a move, or use a hint when a puzzle has you stuck
- Mistakes add to total solve time, see if you can solve it with zero!
- Several color themes to match your style

CubiClear is free to play and supported by ads. Lives regenerate over time, and a single one-time purchase removes that limit entirely if you'd rather just keep playing, and also removes ads.

One piece at a time. Clear the cube.
