Scalak

In Scalak, blank space is part of the puzzle. Separate geometric pieces sit on the board, waiting for the right fit. Slide them into the layout, study the gaps, and build a full square from scattered parts. Some solutions come from shape matching. Others depend on how the pieces share the grid and leave room for one another. Calm music plays in the background, which suits the measured pace and long pauses between moves.

How to play?

Scan the board before touching anything. Check the outline, spot missing sections, and look for pieces that already match an edge or corner. Drag a piece with the mouse or your finger. Rotate it when needed, then place it into the open space. If the shape blocks the layout, pull it back out and test a different position. Finish one board to move to the next puzzle.
