How to play 4096 Skyline

Numbers stand in four towers, like a city skyline. Tap the space above a tower to drop the next number on its roof; the next number is always on show. The top number of a tower is its roof, and a roof is open when its tower stands taller than the tower beside it on at least one side. The two end towers have open ground beyond them, so their roofs are always open. Tap an open roof, then an open roof with the same number: the first flies over and the two twins merge into their double, so two 8s make 16. Only two equal numbers ever merge, and a dropped number never merges on its own. The game ends when every tower is five numbers tall and no two open roofs match. Build a 4096 to win.

When your best tile reaches 64, the 2s retire and new numbers start at 4. Each doubling after that retires the next number. You can also drag an open roof onto its twin. With a keyboard: ← and → pick a tower, ↓ drops the next number, Space or Enter picks a roof and merges it onto a twin, Esc lets go. U undoes a move, 3 per game.
