There are eight humorously-named computer players in all who you’ll face in a random order with the exception of the final opponent, Jammy Jim. Apart from him, none of them have set skill levels and the difficulty will gradually increase regardless of who you’re facing. It’s also possible to play against a human opponent or ‘tune up’ which is basically a ’round the clock’ training mode to get you used to the controls. It’s a good idea too as the disembodied hand you use to throw your darts is constantly moving and can only be moved in the four diagonal directions.
