Scoring

Result	Effect	Example (Target: D5)
Hit the double	Add the double’s value per hit	D5 = +10 per hit
Miss all 3	Deduct the double’s value from your score	-10 points
Bull round	D25 = +50 per hit, miss all 3 = -50	D25 = +50 per hit

• Multiple hits in one turn all count: hitting D5 twice = +20 points
• You only need to hit the double - singles and triples on that number don’t count

Variants

Variant	Description
Easy	No elimination - play all 21 rounds regardless of score
Hard	Eliminated if your score drops to 0 or below. Last player standing wins

Strategy Tips

• Consistency is key - Even one hit per round prevents the deduction
• Early rounds are forgiving - D1 through D5 cost little if missed, use them to find your rhythm
• D20 and D25 are high-stakes - Missing costs 40 or 50 points; hitting rewards the same
• Track your personal best - Bob’s 27 is an excellent benchmark for doubles improvement over time
