3-D Tic-Tac-Toe is an adaptation of the board game of the same name for the Atari 2600. It plays just like Tic-Tac-Toe, but on a 4x4x4 cubic space. Whoever can get a row of four in any dimension wins the game.
In this run, Walgrey plays against the computer at the easiest difficulty and manipulates it into letting her win a single game as fast as possible.
There are alternate encodes that remove all the fades-to-black to make it easier to follow the run.
