All about Crokinole

The game of crokinole appears to have developed in rural Canada in the 1860s. A unique blend of several older English, French, German and East Indian games, crokinole has been an enduring family favourite for close to 140 years.
And while many rules and variant playing methods have developed throughout North America, it appears that one basic set or pattern of acceptable rules has emerged from it all.
The following, then, is the distillation of what seems to be the most common, popularised, 'settle-the-squabble' rules for fair, enjoyable crokinole play. (For dozens of other regional variations, manufacturer's specific rule choices, tournament rules and unique games to play on the crokinole board, please consult The Crokinole Book by Wayne Kelly).
The object of the game is to position shooting discs on the playing surface in such manner that they remain within the highest scoring circles by the end of the round.
A crokinole shot is accomplished by firmly holding the end of your index or middle finger against the thumb and then flicking or snapping it against the disc in order to propel the disc across the playing surface. Each player seeks to make a "20" (centre hole) score whenever possible.
At the same time, each player - in turn - will attempt to make such scoring opportunities difficult for his opponent. The game is played to 50, 100, or more points, as determined by all players in advance.
When two players are playing, each player will have 12 discs (of the same colour) to shoot. They will oppose each other. When four players are playing, each player will have 6 discs to shoot.
The players sitting opposite each other will constitute a team (shooting the same colour) and will oppose the other team.
