Puzzle Block: Slide

A square frame waits to be filled from the inside. In Puzzle Block: Slide, colored pieces glide across the grid and leave their color on the border they reach. The board changes with every move. Black pieces add a removal rule that wipes out neighboring blocks after one reaches the matching black edge. A three-minute limit hangs over each round, and higher scores come from clearing the board before time runs out.

How to play?

Slide the blocks left, right, up, or down across the grid. Push them into the border to paint the wall with the required color. The black block triggers a chain removal after touching the black side of the frame. Nearby pieces vanish with it. Continue shifting the remaining pieces until nothing stays on the board. Each level ends within three minutes or if the round is lost.
