Halite is an artificial intelligence programming challenge.

Players control a bot using the programming language of their choice. Bots fight for control of a 2D grid. The bot with the most territory at the end wins. Victory will require micromanaging of the movement of your pieces, optimizing your bot's combat ability, and braving a branching factor billions of times higher than that of Go.

coders are already playing! The simplest Halite bot is just 10 lines of code, and it takes less than a minute to get on the leaderboard. Interested?
