Merge Rush

Merge Rush is played on a 4×4 grid. Use the arrow keys or swipe to slide all tiles in one direction at once. When two tiles of the same value collide, they merge into a single tile worth their combined total. After every move a new tile — a 2 or occasionally a 4 — spawns in a random empty cell.

The game ends when the board is full and no adjacent tiles share a value, leaving no valid merges. Your score is the running total of every merge you make: combining two 32s adds 64 to your score, two 512s add 1024, and so on. Reaching high-value tiles requires consistently setting up chains of merges rather than treating each move in isolation.

Corner strategy. A common approach is to anchor your highest tile in one corner and build a descending sequence along the two edges that meet there. This keeps large tiles out of the way while leaving room to maneuver smaller ones.

Avoid orphaned tiles. A tile that can only be merged in one specific direction becomes a liability the moment something blocks that path. Try to keep tiles in positions where more than one slide direction still has a use for them.
