By properly analyzing these data points by slot machine over time, processing millions of plays on every slot on every property, looking at factors such as denomination, location, game manufacturer and game type, a casino will get a precise picture of when, where, how and why customers play the specific slots.
The SAS or also known as IGT’s Slot accounting system is the industry standard when it comes to slot accounting protocol for gaming machines such as video slots or stepper reel slots. It’s an industry standard because IGT is the 500 pound gorilla in the industry and pretty much forced everybody to adopted it. Their latest version is the SAS 6.02 protocol.
Obtaining documentation on it is very difficult unless you are a member of Gaming Standard Association. Becoming a member will set you back about 10 grand per year which is a small chunk change if you are a big gaming company or half your networth if you are a hobbyist. As a small time hobbyist, what can you do? You can reverse engineer their protocol by going to ebay and get a cheap IGT’s S2000 machine and connect your serial port sniffer and that is what I did.

It may look like a regular slot machine and play like one, but a video lottery terminal differs quite a bit in terms of how winners are determined.
VLT gaming machines are usually equated more with games like bingo, pull-tabs, scratch-offs, or lotto than they are with slot machines. This is because there are a pre-determined number of winners, and players are competing with each other for a prize rather than against the house. There is also not necessarily a winner in each game.
VLTs are most often found in Indian gaming casinos or “racinos” (location with both a horse racetrack, as well as a casino). Each machine or terminal in a casino is linked together, forcing players to compete against one another for the prize, and with a set number of wins and losses, the group of machines is preprogrammed to payout at specific times.
The only catch for VLT machines is that players must announce their win in order to get the payout because the games are interactive. Although not every game has a winner, the game will be ongoing until a winner is determined.
As indicated by the name, video lottery winners are determined much like a lottery scratch card. Basically, when a game starts on a VLT, the system the machines are connected to randomly chooses a “scratch-off ticket” from those that remain. Once it receives the information regarding the winner, it sends the results to the VLT to reveal the winner, typically in some entertaining way.
Winning at VLT Machines
Obviously, the machine doesn’t have the ability to actually scratch off a ticket, but it does choose the winner from a pool, similar to a lottery ticket. Once all the outcomes in a pool are chosen, the central system receives a new pool.
The payouts can be slightly different on VLTs, as well. According to readybetgo.com, “The final results wouldn’t be noticeably different if the RNG simply picked one number from a group of numbers. Thus the mathematic methods of supplying the decisions in VLTs may be radically different than traditional RNG methods. But in the end, 1 in 10 is still 1 in 10, and 1 in 5,000 is still 1 in 5,000.” The artible goes on to explain that the reason VLTs can be slightly tighter is that they’re offered in areas where there is little competition. In fact, the typical payout is anywhere from 85% to 92%. So, if you’re playing in a casino that offers both VLTs and traditional slots machines, you’re probably better off with the latter.
Slot machines often referred to as “Vegas-style” or traditional slots are the machines you’re probably used to playing. Each traditional slot machine in a casino plays independently from other machines. The only way in which they are linked is usually in terms of the jackpot, but this is only for progressive networks.
Contrary to popular thought, there is no way to know if a certain machine is “hot.” The typical belief is that if a machine has just paid out, you shouldn’t play on it. This is simply not true. Because of the Random Number Generator, each machine has exactly the same likelihood of paying out. Unlike VLTs, slot machines are also not preprogrammed to pay out at any time, so you always have a chance at the jackpot!
When Do You Win?
To put players at ease who may have abandoned a machine in the past only to watch it pay out for the next player, you must understand that RNGs are programmed down to the millisecond, so the odds of winning if you had stayed are low. Because of this, the lever must be pulled at almost the exact time the winning number is generated.
Unlike VLTs, slot machine wins are immediate, and winners don’t have to announce their win to receive a prize. Although, I wouldn’t discourage any hooting and hollering if you’ve just landed a $10,000 jackpot. You earned it.
