If you hit the outer ring of a number, it counts as two, and if you hit the inner ring, it counts as three (unless you aim for the bullseye, in which case the outer ring counts for one and the inner circle counts for two).
In cricket, players must “close out” their numbers, which means they must score 15 through 20 and the bullseye three times before they can win. In this game, players throw three darts at the board while trying to hit 15 through 20 and the bullseye. Once the numbers 15 through 20 and the bullseye have been “closed out,” the objective of Cricket is to score more points than the other team.
Three darts (or more if you don’t want to share).
