Had to look it up, posting so others don't have to.
>The set consists of a throwing pin, and 12 shorter wooden pins (also called "skittles") numbered from 1 to 12. The pins are initially placed in a tight group in an upright position 3–4 meters away from the throwing line. The players take turns to toss the throwing pin to try and knock over the numbered pins.
>Knocking over one pin scores the number of points marked on the pin. Knocking 2 or more pins scores the number of pins knocked over (e.g., knocking over 3 pins scores 3 points). A pin does not count if it is leaning on the throwing pin or one of the numbered pins (it must be parallel to the ground to count).
>After each throw, the pins are stood up again in the exact location where they landed. The first player to reach exactly 50 points wins the game. Scoring more than 50 will be penalized by setting the player's score back to 25 points. A player will be eliminated from the game if they miss all of the numbered pins three times in a row.
Sounds like an interesting outdoors game, piss-easy to /diy/ the pieces too, and thats exactly what Im going to do.
