A chariot-racing game with pre-race rounds of card auctioning - the trick being that the race-winning "pot" is made up of the auction bids. You have to balance the cost of the cards against the likely return - you want good cards cheap, and you want to force your opponents to pay over the odds for their cards. Of course, everyone else is trying to do the same thing.
However, there is a great deal of luck in the actual movement during the race, so your careful planning can be destroyed by a few poor dice rolls.
I made these boxes to hold half the Ben Hurt cards each. Just print, fold & tape! The picture taken (& modified) from the dvd cover of Ben Hur.
Edit: When printing, make sure it prints at "Actual Size" otherwise your cards probably won't fit correctly.
