So, I had a glimmer of an idea this morning about a zombie racing game. The idea is that each player is the owner of a racing zombie. The zombies start in the middle of a hex map, and move semi-randomly toward the edge. Similar to frog/turtle racing.
I was thinking that players, after each round of movement, could place bets on other zombies for which place they would finish: Win, Place or Show. Obviously, the owner of a zombie should make more than one of the bettors, but I was thinking that an owner whose zombie is not performing well could make several bets on other zombies and still come out ahead.
So, my question is this: does anyone have an example of a game with a betting mechanic like this, where players can change their bets during the race? Gold Digger, while not a racing game, has claims on different mines, so it's sorta similar.
