Idea: Secret Betting Society – A way to win money

A secret betting society is a secret society whose members flood a casino, trying to surround and hog the gaming tables so their members are the only people playing.

Rules of the society –

1. Members must agree to share out all the money that they win with other members of the society.
2. Members must appear to be competitors so that the casinos never guess they are all together; they must never be seen together in public; must never openly associate with each other; must pretend not to know each other.

Why is this appealing?:

Say that the members of your secret gambling society managed to surround and hog a gaming table laying large bets; number 1 - they would have numbers on their side and thus a good probability of winning AND number 2 - because they’re all secretly on the same side whenever anyone wins the society would win and thus all its members would win.
