It's pretty simple, being able to dice against "the server". Example: /gamble 100 3 total 25000
Using the /gamble command would do the same as /dice except it would dice against the server. This could bring money out of the economy easily because I know dicers that go til' broke 99% of the time. The only reason they hold onto a little cash is because nobody else is dicing.
I came up with this in like 2 minutes, please don't kill me.
