• The classic slot machine design works on an elaborate configuration of gears and levers. The central element is a metal shaft, which supports the reels. The central element is a metal shaft, which supports the reels.
• So machine X might be able to be set to 100.7%, 99.5%, 98.3%, 85.4%, and 75.7%. Part of having a machine approved for sale is that millions of simulations are run on the machine itself to verify that the random number generator will, over time, pay back at least the percentage the machine is set to.
• This is because players like instant gratification. Proper big wins only occur once every 20 spins or so. Now, this aspect of the slots software is not random. Software developers actually hire specialist gaming mathematicians to design their slot games; it is perfectly legal to tweak the odds of different types of wins occurring.

Slot machines are the most popular game in modern casinos. If you’ve never seen one, a slot machine resembles an arcade game that has a lever on its side. For a small fee you can pull the lever, and the machine will generate a random combination of three symbols. If the correct combination appears, you can win a prize, maybe even the jackpot.

What Interface Design

Slot Machine Interface Design Tool

Slot machines make fantastic profits for casinos because they offer a very low payout rate. In many games, such as Blackjack and Roulette, the odds are only slightly stacked in the casino’s favor. In the long run, the casino pays back 97 to 98 cents in prizes of every dollar that a gambler spends on these games. With slot machines, it is typical for a casino to only pay back 90 to 95 cents—and the casino keeps the rest. If this seems underhanded, keep in mind that slot machines are one of the most popular games at a casino; few people seem to mind. And if you consider that state lotteries have payout rates that are much closer to 50 cents on the dollar, slot machines don’t look that bad.

In this project, you will build a real, working slot machine modeled after some real life Video Lottery Terminals from Manitoba, Canada. The terminals were a source of scandal in the 1990s. You’ll get to the bottom of this scandal by writing a program that recreates the slot machines. You’ll then do some calculations and run some simulations that reveal the true payout rate of the machines.

Slot Machine Interface Design Tutorial

This project will teach you how to write programs and run simulations in R. You will also learn how to:

• Use a practical strategy to design programs
• Use if and else statements to tell R what to do when
• Create lookup tables to find values
• Use for, while, and repeat loops to automate repetitive operations
• Use S3 methods, R’s version of Object-Oriented Programming
• Measure the speed of R code
• Write fast, vectorized R code
