how to play

Just as in 2048, use arrow keys or swipe to move tiles on a 4 by 4 grid in any direction. These tiles are each assigned a power of 2, starting with 2^1 = 2.

The game starts with two randomly-placed tiles of low power (usually 2s, sometimes a 4). When two tiles of the same number touch, they merge into one tile with a doubled value (the next power of 2).

Collect points equal to the doubled value from each tile merge. As you reach higher and higher powers of 2, the tiles heat up from icy blue through molten magenta and scorching yellow to white hot.

The goal is to get a high score as you merge tiles until the game ends, when:
• you reach the 2^N target, or
• the grid fills up with tiles with no moves left

So, choose N wisely!
