c2048 is a 2048 game engine with AI, made in C.
c2048 uses bitmaps extensively, and should have a very fast board implementation. The AI is a simple depth-first search using score + number_or_free_cells as a heuristic.
If you want to change the parameters for the search algorithm, change AI_DEPTH and AI_NUM_TRIES in ai.h.
--human Play on the console, using hjkl to move around
--test Runs some testcases
--ai Runs infinitly many games in a row, while tracking stats (avg, max, nps, etc.)
If you run it with no arguments, it will be able to talk to 4096, a 2048 bot interface made by Mats Lindh:
