2048 Legend

Slide tiles across a grid and any two with the same number merge into one worth double — the whole game is figuring out how to keep merging without running out of empty squares. It's built on the same idea as the original 2048, which itself borrowed from Threes, so if you've played either you already know the rules here. The board fills up fast once you're past the early tiles, and one careless swipe near the edges can end a run that was going well. Chasing a new high score is really the only goal, but that's enough to make one more try tempting.
