Dexter's Laboratory: Chess Challenge is a licensed chess game with a few extra features. In addition to a mode where you just play a quick game of chess, there's also a tournament mode that basically serves as the campaign mode and a Puzzles mode where you have to put the opponent in checkmate under a specific layout and with specific restrictions.

In this run, Walgrey plays Puzzle mode and completes all 30 puzzles in record time.
