Sliding tile puzzle game in the terminal. The goal is to build the elusive 2048 tile by combining two 1024 tiles, which is in turn produced by combining two 512 tiles, which are built up from randomly dropped 2 and 4 tiles.

To combine tiles, slide all the pieces up, down, left or right. Each slide counts as one turn. When two tiles with the same value slide together, they combine, leaving an empty space filled by the tiles sliding in the same row/column and in the same direction. A slide may combine more than one pair of tiles in each row/column.

Valid moves must either combine at least one tile, or move at least one tile. After each valid move, either a 2 tile (90% chance) or a 4 tile (10% chance) will be placed in a randomly chosen empty space. The empty space may be newly emptied in the previous turn.

The score is simply the summation of the value of all tile combinations.

The game is over when no moves are possible.

The controls are Vim-like or arrow keys:

• h slides the tiles to the left of the board
• j slides down
• k slides up
• l slides right
• q quits

The real game uses a luscious 8 colors in two brighnesses (normal and bright). Here's a monochrome screenshot:
