It is only usually seen in exhibition matches, as in tournaments, players are inclined to aim for the triple 20, only switching to the triple 19 for a cover shot. Arguably the most difficult nine dart finish would be 180 (3xT20), 171 (3xT19), and 150 (3xBULL) – owing to the difficulty of getting all three darts in the bullseye: it is the smallest double"

The main differences from English draughts are: the size of the board (10×10), pieces can also capture backward (not only forward), the long-range moving and capturing capability of kings known as flying, and the requirement that the maximum number of men be captured whenever a player has capturing options. These are extra rules accommodated in some tournaments and may vary: Each of the fifty dark squares has a number (1 through 50).

Given a score of 22 — a singly even number — one has a game shot for double 11. If one hits single 11, the new score is 11, which is odd, and it will take at least two further darts to recover. By contrast, when shooting for double 12, one may make the same mistake but still have 3 game shots in"

Since the first dart sets the number, players will sometimes shun shooting at the 20, since a small miss will result in either a 1 or a 5 being set as the number. Often two adjacent numbers with solid values, such as 11/14 and 10/15 are chosen by lower-skilled players, since a small miss there does not result is such a large penalty (if you miss the 14 you'll still land in the 11, etc.).
