How to play 4096 Domino

Swipe a tile to tip it one square that way, like a domino. Onto an empty square it just steps over. Onto its twin, the two merge into their double: two 8s make 16. Then the new tile keeps toppling: if the next square on holds its twin, it falls onto that one too, so a line of 8, 8, 16 and 32 knocked from the end becomes one 64. Each merge is always two equal tiles. A tile can’t tip onto a different number or off the board. Every move brings in the next tile, shown beside Undo, on the empty square marked with its number (if a tile moves onto that square, it lands on another empty one). The game ends when no tile can tip. Build a 4096 to win.

When your best tile reaches 128, the 2s retire and new tiles start at 4. Each doubling after that retires the next number. While you swipe, rings show every twin your tile will topple into. You can also tap a tile and then tap the square next to it. With a keyboard: arrow keys move, Space or Enter picks a tile, then an arrow key tips it; Esc lets go. U undoes a move, 3 per game.
