About Twenty Forty Eight
The 2048 sliding-tile puzzle, with CSS transform animations rather than redraws, so tiles glide instead of jumping. Arrow keys, WASD or a swipe push every tile on the board in one direction; equal numbers that collide merge and double. The board fills a little more with each move, and the run ends when nothing can move. Score is the sum of every merge you make, and your best is kept between sessions.
