Unlock Bloxs

A sliding-block puzzle about opening a route for the yellow block with as few moves as possible.

Shift the surrounding pieces until the yellow block has a clear path off the board.

Unlock Bloxs sets a yellow block inside a crowded sliding puzzle. Other blocks occupy its route, so the central task is to move those pieces aside and create an opening that lets the yellow block leave the board. Each stage tracks how efficiently that arrangement is solved.

About Unlock Bloxs

The puzzle rewards completing a layout in the minimum number of moves, turning every slide into part of a compact route-planning problem. Moving one obstruction can open space for another, while an unnecessary shift increases the solution length even when the exit is eventually reached.

Stages provide separate block arrangements and can award three stars. The mouse or keyboard operates the puzzle, and the portrait frame keeps the sliding board at the center of play. Success comes from freeing the yellow piece rather than clearing every block, so the arrangement should be read around its exit route.

Objective: Slide the surrounding blocks away and move the yellow block out of the board in the minimum number of moves.

Core loop

  • Move an obstructing block, reassess the yellow block’s route, and continue sliding pieces until the exit is open.

How to play Unlock Bloxs

  1. Use the mouse or keyboard to slide blocks on the board.
  2. Move the surrounding pieces out of the yellow block’s route.
  3. Guide the yellow block out of the board while keeping the move count as low as possible.
