A pattern where you must cover the numbers in the shape of a bar on your card. If you get those numbers, you win. This pattern has a Static version, Moving version and a Crazy version. The Static version can be on any 2 connecting lines as long as the pattern does not shift during the game. If it does, it is no longer a Static Pattern but becomes a Moving Pattern.

Static Bar	Another Static Bar
Yet another Static Bar	And a last Static Bar
Crazy Bar	Second Crazy Bar
Moving Bar	Crazy and Moving Bar
