Class II Bingo
Class II games are not always looking like regular Bingo games, but they always have a Bingo based math. In such games wins depend on numbers on a Bingo card, which is displayed in the screen corner and can be changed each time.
Class II games can use the artwork similar to "regular Las Vegas style" games for a better entertaining. And Class II games have gotten much more sophisticated nowadays, so they go far beyond regular Bingo for a better experience. It turn out that Class II games practically have no visible difference with Vegas-type games, but they do follow Bingo’s rules and stay legal in certain jurisdictions.
