New tiles 2 – 32

Each turn you hold one number, shown with the one after it. Tap an arrow at the end of a row or column to feed your number in there: it steps onto the edge square and pushes the tiles in front of it one square along, up to the first gap, like a conveyor belt. Then the front tile bumps the tile ahead of it. Twins merge into their double, and the double bumps the next tile in turn, always two at a time. If the edge square already holds your number’s twin, the two merge there and nothing moves. A full row or column only takes a number that matches its edge tile. The game ends when no arrow can take the number in hand. Build a 4096 to win.

New tiles are an eighth and a sixteenth of your best tile, never less than 4 and 2: when your best tile reaches 64, the 2s retire and new tiles start at 4. Hover or focus an arrow to light its line and ring the tiles that will merge. With a keyboard: Tab to the arrows, arrow keys walk round the edge, Space or Enter feeds. U undoes a feed, 3 per game.
