Gambling minigames

Have ideas for three mini games that maybe would be fun..

Two dice games that are fun are "Liers dice" and a version of "throwing pigs". Dice games can be made with little effort. Specially if i leave out some of the flashiness and use the current menu system.

Magic style collectable card game. Maybe been done to death by other RPG:s but it would maybe be fun to do a bit more strategic game out of it. People will probably think that I am trying to rip off Notch again (he's working on a new card game). Cards could be found when killing zombies.

Maybe a version of Five Finger Fillet? You role a dice then what ever it lands on,(lets say six) You then would tap a pattern 6 times and every "round" around the hand it's a new pattern.

Think I've heard about that game before, sounds like a simon saz memory style game. Have to be really quick so people wont cheat to much.

How about gambling bets on rc races to place bets against other players and the winner of the rrace gets all coins. Or distribute the pot depending on what place you make in the race for instance 1st gets the most and last gets the least.

Also maybe zombie arenas where the last person standing gets the coins.
I'll gladly make arenas if needed.
