Tetris-AI

We built a bot to play online tetris better than we ever could, and this bot won a few dollars.

The bot works with screen information and emulates key presses, thus, it can be adapted to any tetris game.

After reading the screen, it uses an algorithm to determine the best piece placement and executes it.

The algorithm has various modes, for example, focusing on getting a tetris, which is clearing 4 lines with a single piece.
