Sudoku is a logic-based number-placement puzzle. The objective is to fill a 9×9 grid so that each column, each row, and each of the nine 3×3 boxes (also called blocks or regions) contains the digits from 1 to 9 only one time each. The puzzle setter provides a partially completed grid.

In Problem Sleuth, Sudoku plays a relatively large role in the game, especially in the final battle against Mobster Kingpin.


Pickle SudokuEdit

Wizard's Sudoku is an even more confusing version, which combines Pickle Sudoku with Q*Bert, Tetris and fucking weird-ass chess. It is Death's favorite game. It is likely a parody or reference to Wizard's Chess from Harry Potter.

AD (who threw his hat down in disgust) and PI had to play this grueling game in order to escape the afterlife.
