ALL OUT DERBY - Policies & Procedures



This game gives the player the opportunity of wagering on the winner of a horse race without going to the track. The current track may offer 6 horses at a time. The track and the # of player positions can be expanded at any time. Players can wager on 1 or all horses if they wish per race. In its current game play, there will be 1 winning horse. Players wagering on the winning horse, will be paid based on how far ahead it is of the next closest horse when it crossed the finish line.

Players must make a bet equal to the posted table minimum. If the posted minimum is $5, and the Maximum is $100 the player may wager up to $600 or as little as $5 per race not counting the side bet wagers. The casino will set these limits.


1. Players will make at least 1 minimum bet on the horse of their choice. They may wager on all 6 horses per race.

2. They will place that wager in the center of the track in their designated player position on the horse they wish to bet on. Player in position 3 on the table will place their wagers on the 3 circle around the horse(s) they wish to wager on.

3. The dealer will start the game by activating the start key on the dealer’s control pad. The game monitor will indicate “Place Your Bets”.

4. When the dealer activates the "End Betting" key, the “Call to Post” trumpets sound. The race is

ready to go.

5. The dealer will now press the “Draw” button. This activates the 2 cards on the monitor that are selected by the games certified RNG software. The game software will track all draws and keep track of them to determine a winner and if the casino offers it, long and short race results. If a dealer makes an error in moving the game piece, the computer tracking takes precedence. The card on the dealer’s right is the horse selected to move and the card on the left is how many spaces that horse will move for that Draw. In this case the #1 horse will move 6 spaces.

As you can see, the dealer screen captured the current Draw (1), the horse outcome (1) and the spaces the #1 horse is to move (6). The draw button goes shaded to protect the dealer hitting it twice by mistake. The shading goes away in a few seconds to allow for another draw. Each draw and horse movement should take less than 5 seconds.


6. The dealer will now move the 1 horse 6 spaces around the track. Below is a picture of the actual game piece. Dealer needs to be accurate in the game piece placement to avoid a difference between the game placement and the computer tracking! This process continues until a winner is determined.

7. The winning horse will have moved 16 spaces around the track. If that horse wins by less than 8 spaces ahead of the next closest horse, the winners are paid 4 to 1 on their wager. If the winning horse wins by 8 or more spaces, the winners are paid 8 to 1 on their wagers.


8. When the horse crosses the finish line, the dealer will take the winning game piece and place it in the center of the track on the winning horse’s wagering area.


9. The dealer will then remove all losing wagers before paying winning wagers.


10. The game has 2 side bets available to the players. The first is a Short Race bet and the other is a Long Race bet. The player is wagering on whether the winning horse crosses the finish line in 7 or fewer draws or 12 or more draws. If the race ends on 8-11 draws, all side bets lose.

Due to the large computational space of the game (18 possible outcomes for each turn for a maximum race length of 19 turns = approximately 1023 possible outcomes) the return to player was calculated by a Monte Carlo simulation of one billion races. After each race was run, the distance between the finish line and the runner-up horse was calculated. These distances were totaled, and the count of each occurrence was used to determine the probability for each occurrence.


Each probability was multiplied by its net payout, and those products were summed to determine the average return to player.


Note: the Long Race and Short Race wager were added after the initial development of the project, so the results for those wagers are based on a second simulation of one billion races; otherwise, the analysis methodology remains the same.



Based on the results of a simulation of one thousand races, the following results were obtained:
