Merge Numbers

How to play

• Slide the whole board with the arrow keys, or swipe on a phone.
• Every tile slides as far as it can. Two equal tiles that meet merge into their double.
• A tile can only merge once per slide, so four in a line become two, not one.
• Each slide drops a new tile in. When nothing can move, the run is over.
• Reach the target tile to win — then keep going if you like.
