The JDC Challenge is a 3-part practice routine: Shanghai 10–15, Doubles 1–20+Bull, then Shanghai 15–20. In 2 Player mode you work through it together, target by target. Doubles-section scoring here uses face value (D1=2 … D20=40, Bull=50) — worth checking against JDC's own guide before treating results as official grading.

JDC Challenge
Shanghai targets (e.g. "Shanghai: 10") β you get 3 darts at that number. Tap whatever each dart hits: Miss, Single, Double or Treble of that number, in any order.
Doubles round the board β once it switches to "Double: D1, D2 …" (and the Bull), it's one dart per double. In 2 Player mode each player throws 3 darts in a row (D1, D2, D3, then D4–D6 and so on, finishing with D19, D20 and the Bull) — choose Hit or Miss for each, then Confirm. In Solo mode it's one double at a time: Hit It or Missed.
33 targets altogether: Shanghai 10–15, then every double 1–20 plus the Bull, then Shanghai 15–20 again.

Finished on a Double?
That score brings Player to zero. Did the last dart land on a double (or bullseye) to finish the leg?
