How to play
- Move every tile in one direction with an arrow key, WASD, or a swipe.
- When two equal tiles meet, they merge into the next power of two.
- Keep open space available and work toward the 2048 tile without trapping large values.
What this game practices
A strong planning puzzle that makes doubling visible. It is useful for discussing powers of two, but success depends more on board management than arithmetic fluency.
