How to play
Make every line match
Select one numbered tile, then select another to swap their positions. The totals above and beside the board update after every move.
Finish when every row, every column, and both diagonals equal the target. A check mark appears beside each correct total, so progress never depends on color alone.
Choose a 3×3, 4×4, or 5×5 grid. Your preferred size stays in this browser, while New game creates a fresh arrangement and resets the timer and move count.
Play your way
Tap, click, or use the keyboard
On a keyboard, move between tiles with the arrow keys and select tiles with Enter or Space. The clock starts with your first tile interaction and stops as soon as the grid is complete. Reduced-motion preferences are respected automatically.
