Rule 1: The primary objective is to combine blocks with identical numbers.
Rule 2: Drag a tile over another tile bearing the same number.
Rule 3: Upon merging, the resulting tile's value will be the sum of the two merged tiles.
Rule 4: If a move doesn't result in a merge, a new row of blocks will materialize at the bottom.
Rule 5: The game concludes when the grid becomes completely filled with blocks, preventing any further moves.

You earn points every time you successfully merge two tiles. The higher the value of the merged tile, the more points you receive.

No, you can only merge two tiles with the same number at a time.

Unfortunately, there is no undo button. You must carefully plan your moves to avoid filling up the grid prematurely.
