About the game

A grid sits in front of you and block shapes keep arriving. Slide one into place so its squares close a whole row sideways or a whole column up and down, and that line vanishes, handing its squares back. Each line you remove pushes your score up.

Nothing you place ever moves again, so gaps pile up where you least want them. A stray hole in one corner can leave a later shape with nowhere to land, and a board with no room left stops the round. You set the pace, which means you can stare at the grid as long as you like before the next drop.

How to play

Move a block with your mouse, or drag it with a finger on a touch screen.
Set it down so its squares fill a complete line across or down.
A finished line clears away and frees those squares for later shapes.
Keep enough open space for what comes next; more cleared lines mean a higher score.
