Can you join the numbers in the right way to create 144?
Use the arrow keys to move the squares all in one direction. Any number of identically valued squares, if in a row, will merge together.
And remember, 144 = 2 × 2 × 2 × 2 × 3 × 3.
For a bonus challenge, try getting 2048 on this grid. It's harder than it looks!
