This is a simple game of elimination for any number of players. It does get a little long when there are alot of players, however.

The Object of Nine Lives Dart Rule
To be the first player to get "around the clock", that is to get at least one dart in each number from 1 through 20 in order.

The Scoring of Nine Lives Dart Rule
Each player throws one dart at bullseye, closest to the bullseye goes first, furthest from the bullseye goes last. Each player gets three "lives" represented by three tally marks below their name. No, I don't know why they call the game 9 lives but you only get 3. Maybe it was invented with 3 players?

The Play of Nine Lives Dart Rule
Each player takes a turn trying to hit each number from 1 through 20. The numbers must be hit in order or they do not count.

If a player misses with all three darts, one life is lost (a tally mark is erased) from that player. When all three of a players lives are lost, that player is out of the game.

The winner of the game is the first player to make it to 20 or the last player in the game to have any lives left.
