The player takes part in 501 darts, competing against other darts players in a championship tournament where standard darts rules apply—scoring reduces your total from 501 to zero, with the requirement to finish on a double. Starting from the quarterfinals, the player must win a best-of-three match to progress through the tournament. Secure another victory in the semifinals to reach the final and challenge the World Champion, Jammy Jim. In the final match, however, the player only needs to win a single leg to claim the title. Players also have the option to compete against another human opponent or play Round the Clock, aiming to hit each number on the dartboard from 20 down to 1 within a set time limit.
