Game Rules: Bob's 27 (Darts)

Game Identity

• Name: Bob's 27
• Player Count: 1–8 players (primarily a solo practice game; can be played competitively).
• Teams: No teams.
• Theme: High-skill darts practice game focused entirely on doubles. Starts at 27 points. Hitting a double adds double its value; missing deducts double its value. Survive all 20 doubles.

Scoring Mechanics

• Scoring Variant: Special — starts at 27. Score changes based on hitting or missing each double in sequence.
• Target Score: No win condition — highest score after all 20 rounds is the goal. Score going to 0 or below ends the game early.
• Unit of Scoring: Points added (hit) or subtracted (miss) per double attempt.
• Lower vs. Higher: Higher score after 20 rounds wins. Surviving all 20 is itself an achievement.

Rules & Validation

Setup

• Each player starts with 27 points.
• The game proceeds through 20 rounds, one per double (Double 1 through Double 20).

Per-Round Logic

• Target: The current double (D1 in Round 1, D2 in Round 2, …D20 in Round 20).
• Each player throws 3 darts per round.
• Hit: Each dart that lands in the double scores double that number (e.g., D6 hit = +12 per dart hitting it).
• Miss: If no darts hit the double, the player's score is reduced by double the number (e.g., miss D6 = −12).
• Elimination: If the player's score drops to 0 or below, they are out of the game (for competitive play; in solo play, continue as a record).

Validation Rules

• Starting score: 27.
• Per-round result: +D×n (hit, where n = number of darts hitting the double), or −D×2 (miss).
• Score can become negative in solo mode.

Special Actions / Bonuses

• Ton-40 Start (optional): Some variants start at 40 instead of 27 to make survival slightly more forgiving.
• Perfect Game: Hitting all 3 darts in each double every round yields an exceptional high score (theoretical max: 27 + 2(1+2+3+4+…+20)×3 = 27 + 1,230 = 1,257).

Win Conditions

• Solo: Goal is to survive all 20 rounds (score remains above 0) and record the highest final score.
• Competitive: After all 20 rounds, player with the highest remaining score wins.
• Tie-Breaker: If tied after all 20 rounds, compare scores at each round from 20 backward. First difference wins.
