Everyone who wants to play must have 5 gems. There would be a series of single elimination games on 20x20 to 40x40 size maps. Players would bet their gems in the games, and bet their total winnings all the way up to the final tier. For instance, in round one you must bet your 5 gems. If you win, you must bet all 10 gems in the next game, etc. The winner of the tourney would win the entire jackpot of gems, as well as some recognition.
Sorry if I'm not supposed to direct a tourney, this is "unofficial"
So who would be in for something like this?
EDIT: For those who may have been confused about the gem thing, here is what an 8-person tourney would look like in terms of gem winnings.
