Goal: Place blocks on the 10×10 grid to fill complete rows or columns and keep the board clear for as long as possible.
How to play: Each turn you receive three random blocks. Click a block from the panel on the right to select it, then hover over the grid to see a ghost preview of where it will land. Click a grid cell to place the block.
Clearing lines: When an entire row or column is completely filled, it clears automatically and you earn bonus points. Clearing multiple lines at once earns even more!
Scoring: You earn 1 point per cell for each block you place, plus 10 points per line cleared. Clearing multiple lines in a single placement awards an extra bonus.
Undo: Click Undo to reverse your last placement – but only before any lines have been cleared.
Game over: The game ends when none of the remaining blocks can fit anywhere on the grid. Try to beat your best score!
