This is what it looks like in my grey-themed terminal:
To play, use your arrow keys to merge blocks of the same number. Try to get to 2048. On every turn, a new number, either 2 or 4, spawns. It is marked in bold. If you're a vim-user, then you can also use h, j, k, l instead of the arrow keys.
I considered making the game colorful, but decided against it, since the game's colorscheme might conflict with a user's terminal's colorscheme. If you want to play a really fancy, colorful command-line 2048, then I suggest checking out term2048.
