2048

Press the arrow keys to shift the tiles up, down, left, or right. Two adjacent tiles of the same value will join to form a single tile to the next power of 2. For example,

• Two “2” tiles will merge into a single “4” tile.
• Two “4” tiles merge into a single “8” tile.
• Two “8” tiles merge into a single “16” tile.
• …and so on.

Do this until you obtain a single “2048” tile. It is good practice for those learning base 2 progression (2, 4, 8, 16, 32, 64, 128, 256,…).

Sounds easy, right? The trick is sliding the tiles in a way so that they can be merged together. As the tiles are shifted, new “2” tiles are added to the board so you never run out of tiles. However, while it is easy to form low numbered tiles, the higher numbered tiles are more challenging. This is where planning is valuable.
