Bob's 27

Goal: work through every Double from D1 to D20, then finish the training on Double Bull while keeping your score above zero and scoring as many points as possible.

You start the game with 27 points. In each round you have 3 darts at one specific Double.

You start on D1 and then continue through D2, D3, D4 ... up to D20. After D20, the final round is played on Double Bull.

Scoring: each hit on the required Double adds its actual dartboard value to your score. For example, D5 adds 10 points, D10 adds 20 points, D20 adds 40 points and Double Bull adds 50 points. Each of the three darts is scored separately.

Penalty for a failed round: if none of your three darts hits the current Double, its value is subtracted from your score. For example, missing D10 with all three darts means -20 points, while missing Double Bull in the final round means -50 points.

If your score falls to 0 or below, the game ends immediately.

Bob's 27 is a Doubles training game that rewards accuracy while heavily punishing missed rounds. The further you progress, the greater both the potential reward and the penalty.

If you survive every round, the training ends after Double Bull.
