Next 2 Merge +1

Swipe a tile and it steps one square that way, onto an empty square or onto its twin: two 8s make 16. A mirror runs down the middle of the board, and every move has an echo: the tile in the mirror square steps the mirrored way (you go left, it goes right; up and down stay the same). If the echo can’t go, it stays; if your own tile can’t go, nothing moves. Two tiles that meet at the mirror merge if they are twins. Every move brings in the next tile on the dashed square, but merges take turns: one is free, the next brings a tile too. The game ends when no tile can move. Build a 4096 to win.

When your best tile reaches 512, the 2s retire, and each doubling after that retires the next number. Tap a tile to pick it (dots show where it can go, rings where its echo will), then tap a square to move; tap it again to put it down. Keys: arrows move a cursor, Space or Enter picks, then an arrow moves the tile; Esc puts it down. U undoes a move, 3 per game.
