Click the green flag to start. The goal of the game is to join tiles together that are the same value. When two tiles combine, they become one tile that's one more the value. As the title implies, your goal is to make a tile worth 11. Use the arrow keys or WASD to shift all of the tiles on the board in the same direction. Every time you move the tiles, a new tile will spawn randomly with a value of one.
