How to read the checkout chart
S means single, D means double and T means triple. Bull means the inner bull worth 50 points. Every listed route ends on a double under standard X01 rules.
Why some scores show no checkout
A score may be impossible because it is above the maximum finish of 170, because too few darts are available, or because its combination cannot end on a double. The recognised three-dart bogey numbers are 169, 168, 166, 165, 163, 162 and 159.
Use the chart for practice
Start by learning one-dart finishes and common two-dart combinations. Then work upwards through larger three-dart routes. Select a score in the chart to open it directly in the calculator.
How to study the chart efficiently
Learn finishes in groups instead of memorising 169 separate rows. Start with preferred doubles, then two-dart finishes from 41 to 80, and finally the common three-dart routes above 80. Clicking a score opens the calculator for alternatives.
