How to Play Dungeon Derby

About Dungeon Derby, from BoardGameGeek:

Dungeon Derby is a game filled with betting, strategy, & a bit of luck. The game consists of unique races. But beware, friends can quickly turn into foes! Semi-Cooperative: Work with fellow players to rig the dungeon and influence races. But beware, friends can quickly turn to foes! Real-Time Play: Players play the game in real time, drawing cards, playing traps/armor before the game begins & playing spells as the race is underway to help determine the outcome. Don't worry, it doesn't make the game chaotic, just move along at a nice pace. The Gamble is the Glory: Place your bets on the champion(s) you think will win the race, then roll the dice to see if fate is on your side. -description from the publisher
