Okay, so I redid the script, after all it kind of sucked from the start. I used the "'" trigger because no one else I know used it. But I changed it up a bit. The new version doesn't have roulette, since that was just a pain, plus there were too many things to idiot proof. New Commands: 'dice (opponents name here), 'self, 'loan and 'stats

Dice: throws dice with an opponent, betting that you'll get a higher number.
Self: allows you to gamble with yourself between either dice or a slot machine.
Loan: sets your money back to 100, and if you don't have money, it does the same.
Stats: allows you to see the amount of money you, or a given nick has left.

So yeah, enjoy :D
Plus I also made a cheat for a master/person you trust very much, so you always win xD
just type /master and enter the person's nick in the box :D
Have fun!
I'll have a 'ghelp command soon, but at the moment I'm a little busy.
