Chapter 1: 41-60
The best way to check out 60 is:
20 – D20 = 20
Only one good option here. Single 20 leaves D20. This can be tricky because your dart will tend to block your view of the D20. Be careful not to bust your score by hitting the T20 on your first dart.
ADVANCED PLAYERS: Try to aim slightly left or right in the single 20 segment. You want to try and leave an unobstructed path for your second dart that doesn't require you to move your feet left or right.
