Cricket Darts Rules
How do you play Cricket darts?▼
Cricket darts is played on numbers 20, 19, 18, 17, 16, 15, and the bullseye. Each player needs 3 hits (marks) to 'close' a number. Once you close a number that your opponent hasn't closed, you score points for additional hits. The first player to close all numbers AND have equal or more points wins. You need to hit the single (1 mark), double (2 marks), or triple (3 marks) to score marks on each number.
What's the difference between Cricket and Tactics in darts?▼
Cricket uses numbers 20-15 plus bullseye (7 numbers total), while Tactics uses numbers 20-10 plus bullseye (11 numbers total). Cricket is the more common and faster-paced version, while Tactics requires more strategic play across more numbers. Both use the same marking and scoring system.
How do you score points in Cricket darts?▼
You score points in Cricket by hitting numbers you've already closed (3 marks) while your opponent hasn't closed them yet. Points equal the number value - hitting 20 after closing it gives you 20 points. You cannot score on numbers your opponent has already closed. The strategy is to close numbers quickly while preventing your opponent from scoring.
X01 Games (501 Darts)
How do you play 501 darts?▼
In 501 darts, each player starts with 501 points and throws 3 darts per turn to reduce their score to exactly zero. You must finish with a double (outer ring) or bullseye depending on the game rules. If you go below zero or don't finish correctly, it's called a 'bust' and your score returns to what it was before that turn. The first player to reach exactly zero wins.
What does 'double out' mean in darts?▼
Double out means you must finish the game by hitting a double (the thin outer ring of the dartboard) or the bullseye. For example, if you have 32 points left, you need to hit double 16 to win. This rule makes the game more challenging and strategic, as you need to leave yourself even numbers for easier finishes.
What's the difference between 301, 501, and 701 darts?▼
The numbers represent your starting score. 301 is shorter and more aggressive, typically finished in 3-5 turns. 501 is the standard tournament length, usually taking 6-10 turns. 701 is longer and more strategic, often taking 10+ turns. All use the same rules but require different strategies due to the varying game length.
