The main thing most people already know about these electronic gaming slot machines is that they are the most popular and lucrative gaming items in any casino in Macau. In some countries in Europe this may not be the case, but in Australia it is the same, only they refer to the game as “poker machines” or “pokemon”.
However, if you read all the articles in this section of our site, you will know enough about these games to reasonably call yourself a “slot expert”.
We don’t have a magic formula for how to win at these games, but we do have some insights into the math that slot machines can share.
We believe that educated gamblers have more fun and increase their chances of winning.
What are electronic gaming slot machines and how do they work?
electronic gaming slot machines are gambling games with spinning reels. These reels have symbols on them, and after you place a bet and spin the reels, they stop randomly. If the symbols align, you win, depending on which symbols land on that “payline”.
These games have been around since the late 19th century, but since then they have done nothing but popularize. They were originally mechanical devices that relied on springs and gears to spin the reels. Modern slot machines use a computer program called a random number generator to determine which symbols land where.
A random number generator is a computer program that loops through thousands of numbers per second. When you press the spin button, the program will stop at any position. These numbers correspond to the blocks and symbols on the reels.
Early slot machines
Early slot machines had easy-to-understand math. You may have 3 reels with 10 symbols on each reel. The odds of getting any particular symbol are equal to 1/10.
If you want to calculate the odds of getting a particular combination of symbols on a row, you just need to make 1/10 X 1/10 X 1/10 equal to 1/1000.
You can then compare the payouts for lining up those symbols with the chance of hitting the combo to figure out the machine’s ROI. If a casino offers 998:1 odds on a bet with a 1/1000 chance of winning, then the casino will have a very low edge. They show profits over time.

Modern slot machine tables are difficult to calculate because the symbols and reels are programmed into the computer. This makes the game more flexible in many ways. For example, they are not limited by reel size.
Before the game became literally and physically too big to be practical, old mechanical slot machines could only have 10+ symbols on the reels. However, the computer-driven game may have 20 symbols per reel.
Another advantage for manufacturers is that they can adjust the odds of certain symbols appearing. Some symbols will appear once every 10 spins; others may only appear once every 20 or 30 spins. This enables manufacturers and casinos to offer bigger jackpots and still keep their casinos profitable.
Slot games are available in a variety of denominations and feature a variety of features. You can play with chips, nickels, dimes, coins and banknotes. You can also play with 5 reels and 25 paylines. Scatter symbols, wild symbols, bonus games and jackpots all add interest and variety to the slot game.
It’s no wonder that an estimated 70 to 80 percent of most casinos in Macau’s revenue come directly from these slot machines.
