How to Play

1

Slide the Tiles

Use your Arrow Keys (or swipe on mobile) to move all tiles on the grid in one direction: Up, Down, Left, or Right.

2

Merge Identical Pairs

When two tiles with the same number touch, they merge into one! The new tile will be the sum of the two original values (Double the Number).

3

Manage the Grid

Every time you move, a new tile appears in an empty space. If the grid fills up and no more merges are possible, the game ends.

4

Chase the High Score

The game continues as long as you have room to move. Focus on creating large numbers to maximize your total score.
