I can keep track of a seperate bank, if that idea works out.

For the races... I can do it, but I'm looking for something else at the moment. I want a game where the random number generator isn't used. I've got two ideas at the moment, but they are mutually exclusive. Conceptually, they are very similar, so running both would be bad.

1) Boards scavenger hunt. For this, I'll need approval from the mods, as well as the help of one of them. Various posts will be editted to contain a password. They will be marked with "Casino password: ". Together, they form a phrase. The first player to figure out the phrase wins the prize. To play, you pay up 1 point, the winner receives all the points. Passwords will be put in old battles, early water-cooler thread posts, and the like, so as not to interfere with anything. A mod will be in charge of placing these passwords around the place, and that mod will be asked not to give away any details. Obviously that mod will not be allowed to play. As an example, the phrase might be "So, I heard you like mudkips." In which case, 6 posts will be editted, adding in the lines:
"Casino password: So,"
"Casino password: I"
"Casino password: heard"
"Casino password: you"
"Casino password: like"
"Casino password: mudkips."

2) Virtual scavenger hunt:
Each player who wants to play pays a point, and will receive an object. That player then "hides" the object with a password. From there, the game is a series of rounds. In each round, each player gives the password for the object they wish to find this round. If they successfully find it, they remain in the game, failure to do so will remove you from the game. Additionally, they send in an object they wish to have removed from the game. The object with the most votes will be removed from all future rounds: presenting that password will remove you from the game. Passwords must be presented with their corresponding objects (since objects are unique, but I can't guarantee that for passwords). Additionally, you can change the password of an object you find in a given round. The winner receives all the points that were put into the game.

Board scavenger hunt is simpler, while virtual scavenger hunt is entirely in the players hands. Dunno how much that matters to you guys. Also, virtual is more likely to be approved, but the board scavenger hunt requires a mod editting old posts, which means work for them. Dunno if they are up for that.
