Carol Vorderman's Sudoku is a simulation of a sudoku game for the PlayStation Portable console. The game features multiple modes, including a classic mode, four arcade modes that focus on accuracy and speed, and two career modes that challenge players to complete increasingly difficult puzzles within a time limit.
The game includes various multiplayer modes, such as Free For All, where both players work on the same puzzle at the same time, competing to fill in the most squares; Quickfire, where players take turns filling in squares, with the fastest winner; and Time Attack, which gives each player a separate puzzle, with the fastest completion time being the winning condition. All multiplayer modes have adjustable handicaps.
Additionally, the game includes tutorial videos and a sudoku solver to aid players. Stats are tracked across games, and saved to the memory card for reference.
