4-in-1 Fun Pak is a collection of board games for the Game Boy. It includes the games Checkers, Chess, Reversi, and Backgammon, and has the option to either play against a CPU or against another human player by either sharing the Game Boy or linked with another Game Boy using the Link Cable.

In this run, BlackWinnerYoshi and Spikestuff play Chess in "2 Gameboys" mode, the 2 player mode with two linked Game Boys, and work together to achieve the fastest "Fool's Mate" possible.
