Game objective: practise checkout situations starting at 121 and progressing through higher values.
You begin at 121 points. You have up to 3 attempts at each target, with each attempt consisting of up to 3 darts.
If you successfully complete the current checkout, you move on to the next value.
The checkout must be completed using the standard Double Out rule. The 50-point Bull may also be used as the finishing dart.
The exercise progresses through checkout values from 121 to 170. Your goal is to complete as many of them as possible.
