Multiple Options
Bust Detection
The calculator automatically detects busts in real-time. A bust occurs when:
- A score would take a player below zero
- The remaining score would be exactly 1 with Double Out enabled
- An attempt to finish without hitting a double (when Double Out is on)
When a bust is detected, a visual shake animation and toast notification appear, and the turn is forfeited with no score change.

Nine strategically selected quick-entry buttons cover the most common dart scores in competitive play:

Frequently Asked Questions
What does "Double Out" mean?
Double Out is a rule where the last dart thrown to win the game must land on a double segment of the dartboard (the outer narrow ring) or the bullseye for a score of 50. This is the standard rule in most competitive dart games and professional tournaments. For example, if you have 32 points remaining, you must hit Double 16 to finish the game.
What is a bust?
A bust occurs when a player's score goes below zero, or when Double Out is enabled and the remaining score would be exactly 1 (since no double equals 1). When a bust happens, the turn is lost and the player's score remains unchanged from before that turn. The calculator automatically detects busts and displays a visual notification.
What do D, T, and Bull mean in checkout suggestions?
These are standard dart notation abbreviations used in checkout suggestions:
- D stands for Double (e.g., D20 = Double 20 = 40 points) — the outer narrow ring
- T stands for Triple (e.g., T19 = Triple 19 = 57 points) — the inner narrow ring
- Bull means the bullseye, worth 50 points and counts as a double for finishing
For example, a checkout suggestion of "T20, T20, D15" means Triple 20 (60), Triple 20 (60), Double 15 (30) for a total of 150 points.
Why is the maximum score per turn 180?
Each turn consists of throwing 3 darts. The highest possible score with 3 darts is achieved by hitting Triple 20 with all three darts: 60 × 3 = 180 points. This is the maximum possible score in a single turn and is considered a perfect round in darts.
Can I undo after the game ends?
Yes, absolutely! If you accidentally enter a wrong score that ends the game, you can press the undo button or use the keyboard shortcut Ctrl+Z to reverse the last turn. This will remove the game-over screen and allow you to continue playing from the previous state. The undo function works even after the winner screen is displayed.
Is my data saved?
The game runs entirely in your browser using client-side JavaScript. No data is sent to any server, and no information is stored remotely. This ensures complete privacy and allows the calculator to work offline. However, if you refresh the page or close your browser, the current game will be reset and all progress will be lost.
