JDC Challenge

The JDC Challenge is a structured, three-part solo training routine designed to measure a player's all-round scoring ability. The goal is to accumulate the highest possible total score across two Shanghai rounds and one doubles round, then compare your result against a standardised grading system. Grades range from the entry-level White tier to the elite Black tier, giving players a clear benchmark for tracking improvement over time.

You need a standard dartboard, a set of three darts, and a scoresheet (or app) divided into three sections: Part 1 – Shanghai 10–15, Part 2 – Doubles 1–20 + Bull, and Part 3 – Shanghai 15–20. The scoresheet should have space to record individual throw values, any Shanghai bonuses earned, and a running cumulative total.

The JDC Challenge is a solo practice routine — there is no throwing-order determination. However, when used in group or academy settings, multiple players may complete the routine independently and compare final scores afterward. The routine was created by Steve Brown and the Junior Darts Corporation (JDC) as the official grading system for youth players attending JDC Academies in the United Kingdom, though it is now widely used by players of all ages and skill levels.

The challenge is completed in three consecutive parts, always played in the order below. A player must finish all three parts to produce a valid final score.

Part 1 – Shanghai (10–15): The player throws three darts at each number from 10 through 15, in ascending order — six visits in total. Every dart scores its face value (singles, doubles, and trebles all count at their standard point values). If, within a single three-dart visit, the player hits a single, a double, and a treble of the target number, this constitutes a Shanghai and earns a 100-point bonus on top of the face values scored.

Part 2 – Doubles (1–20 + Bull): The player throws one dart at each double, working from Double 1 through Double 20, then finishes with one dart at the bullseye — 21 darts in total. Each double hit is worth 50 points (regardless of which double it is). A miss scores zero for that dart. On the final throw at the bullseye: if the player hits the inner bull, they score 50 points plus a 50-point bonus (100 points total for that dart). A miss at the bull scores zero.

Part 3 – Shanghai (15–20): The player throws three darts at each number from 15 through 20, in ascending order — six visits in total. Scoring works identically to Part 1: all darts count at face value, and a Shanghai (single + double + treble of the target number hit within the same three-dart visit) earns a 100-point bonus.

Note that the numbers 15, 16, 17, 18, 19, and 20 appear in both Part 1/Part 3, or solely in Part 3. Specifically, numbers 15 appears in both Shanghai rounds, giving extra weight to performance on that segment.

Standard dartboard values apply throughout the Shanghai rounds:

• Single segment: face value (e.g., single 12 = 12 points)
• Double ring: 2× face value (e.g., double 12 = 24 points)
• Treble ring: 3× face value (e.g., treble 12 = 36 points)

Shanghai bonus: If a player hits a single, double, and treble of the same target number in one three-dart visit, they receive a 100-point bonus in addition to the face values. For example, hitting single 15 (15), double 15 (30), and treble 15 (45) in one visit scores 15 + 30 + 45 = 90, plus the 100-point Shanghai bonus, for a visit total of 190 points.

Doubles round scoring: Each successful double hit scores a flat 50 points. Hitting the inner bullseye on the final dart of the round scores 100 points (50 + 50 bonus). For example, a player who hits 12 out of 20 doubles plus the bullseye would score (12 × 50) + 100 = 700 points for Part 2.

The player's final score is the sum of all three parts. There is no maximum theoretical cap, but an exceptionally high score requires consistent treble hitting, multiple Shanghai bonuses, and a clean doubles round.

The JDC Challenge is not a head-to-head competitive game; it is a personal performance assessment. A player's final cumulative score is compared against the official JDC grading tiers, each associated with a coloured t-shirt level:

• White: 0–149
• Purple: 150–299
• Yellow: 300–449
• Green: 450–599
• Blue: 600–699
• Red: 700–849
• Black: 850+

The Black grade (850 or above) is considered elite-level performance. Players are encouraged to repeat the routine regularly and track their grade progression over weeks and months. In academy or group settings, players may compare scores informally, but the primary measure of success is individual improvement from one attempt to the next.

Adjusted Ranges: Some informal versions modify the number ranges used in the Shanghai rounds (for example, starting at a lower number for younger or beginner players) or adjust the number of darts thrown per visit. These adaptations are not part of the official JDC specification but can make the routine more accessible.

Group / Academy Format: In JDC Academy sessions, multiple players complete the challenge simultaneously (each on their own board or taking turns) and scores are compared on a leaderboard. This adds a competitive element while preserving the individual-assessment structure of the routine.

Digital Versions: The JDC Challenge is available on several darts scoring applications, such as GoDartsPro, which automate score tracking, apply Shanghai bonuses, and display the corresponding grade tier in real time.

Hunt the Shanghai Bonus: Each Shanghai bonus is worth 100 points — more than many entire three-dart visits. When you have already hit two of the three required segments (single, double, treble) with your first two darts, deliberately aim for the missing segment with your third dart. A single Shanghai bonus can be the difference between one colour grade and the next.

Treat Every Double as a 50-Point Opportunity: In Part 2, every double you miss is 50 points left on the board. Slow your rhythm, reset your stance before each throw, and give each of the 21 darts full concentration. A clean doubles round alone can push you comfortably into the Blue or Red tier.

Prioritise the 15–20 Segment: Numbers 15 through 20 appear in the Part 3 Shanghai round and number 15 also features in Part 1. High-value trebles in this range (treble 20 = 60, treble 19 = 57, treble 18 = 54) generate the most face-value points per dart, so devoting extra practice time to the upper segments of the board pays dividends in two of the three parts.

Track Your Scores Over Time: The real value of the JDC Challenge is longitudinal comparison. Record your score after every attempt and note which part contributed the most — and the least — to your total. If your Shanghai rounds are strong but your doubles round is weak, redirect practice accordingly. Consistent tracking turns the routine from a one-off test into a powerful diagnostic tool.

Set Incremental Grade Targets: Rather than chasing the Black tier immediately, aim to move up one colour level at a time. If you are currently scoring in the Yellow range (300–449), set a concrete short-term goal of reaching Green (450). Small, achievable targets sustain motivation far better than distant, aspirational ones.
