If you're looking for a way to stretch your bankroll while still seeing some action, you might be interested in the electronic horseracing game known as “derby.” Derby can usually be found in larger casinos that offer sports-books, and often it's located near the sportsbook area of the casino. The minimum bet for this game is usually twenty-five cents, and usually you can bet between one and twenty coins on each race.

The only bet available in derby is the quinella, or choosing the first and second finishers in either order. Odds for each of the possible quinellas are posted on a board before each race. Odds for derby are “for one” instead of “to one,” which means you don't get your original wager back. Payouts typically range from 2 for 1 to more than 150 for 1, though these will vary from casino to casino. House edges on derby range from about 10 percent to 20 percent.
