Black Board 2048 is a branch version which is funny and different.
The games objective is to slide numbered tiles on a grid to combine them to create a tile with the number 1.
Every turn, a new tile will randomly appear in an empty spot on the board with a value of either 1024 or 2048. Tiles slide as far as possible in the chosen direction until they are stopped by either another tile or the edge of the grid. If two tiles of the same number collide while moving, they will merge into a tile with the 1/2 value of the two tiles that collided.
