can I change the % pay out on my igt triple rwb? 25¢ machine. game prom 1148 reel 7550. its at 94% right now. what do I need to lower it to like 80%????

how do I change the layout % on my igt s+ triple rwb. my game chip is 1148 and reel chip is 7550. the % now is 94% and I wanna get it down to like around 80%. any ideas?

you need a lower percentage chip. This is odd though, since most people want the percentage higher, not lower.

What Wayne said. All of it.

You can reference the online IGT S+ game bible to see what known chips are availabe for your theme.

You can then do a WTB and specify the chip number alternatively most of the vendors on our main page can help you out.

Another comment on this.
a payout change does not necessarily change the payout behavior of the machine.

The S+ chooses 3 random numbers each time. If those 3 numbers show up in the reel table then you have a winning combo and they get paid out.
The diference between a 96% chip and a 75% chip might be as simple as fewer single cherry pays......

There is no "forced" percent - its just a matter of the odds and a large number of spins.

An example is that you flip a coing 10 times .... you get 7 heads and 3 tails. You could state that this coin pays 70% heads.......
However you flip it 10,000 times and you may get 5800 heads and 4200tails
flip it 10 million times and you might be a lot closer to the expected 50/50

Slot math for the S+ is based on 10million spins so while statistically you will see a difference over a long period of the machine I would not expect to see a massive change right away.

Assuming your reel strips have 256 virtual stops the chances of winning the top prize remains 1 in 256x256x256.... changing out the chip does not change the probability of this winning combo.
If fact there is nothing to say this same winning combo wouldn't come up 6 times a day for the life of the machine. The probablity of that is low but theoretically possible.

Hope this helps.

These machines do hold their payout percentage and are very accurate too, a 90 percent chip will hold back 10 percent. I operate these machines as a business and I can depend on these programs. Whatever chip you have in your machine now, add meter 2 (out), meter 4 (cancel credit) and meter 6 (jackpot) then divide the total of those three by meter 1 (in). The figure you get will match your percentage chip.

First, asgard, you're responding to a post that's almost a year old.


Sorry to disagree, but that is simply untrue*, if you're operating an S+ class III gaming machine.

<EDIT> * To clarify, your description of how to add up the meters to get the current payback percentage is basically correct, although in the chips I use credit collect (cancelled credits) is meter 5.

If you have enough play in your casino and check the slot infrequently enough (in other words, allow enough play between reads), you will probably get readings that are reasonably close to the long-term payback percentage. However, even after 100,000 spins some games will be off more than one might be comfortable with.

The lower the volatility of the game, the less likely it will be to depart significantly from the expected norm. It will also take fewer spins to narrow the standard deviation to a range that most operators would be happy with.

High volatility games (such as 10x pay for the S+ platform) can take more than a hundred thousand spins to begin to approach their expected payout percentage.

Having said that, it's also possible for a machine to end up close to its expected payback right from the start. They don't call it a RANDOM number generator for nothing.


The class III machines (Nevada slots) do not use past spins or payouts in any way to determine each outcome or to "adjust" the percentage.

I know its an old post but I just wanted to let people know that the payout percentage is real. Meter 5 is for newer machines, I was referring to the S+. In my country where the gaming inspectors are trained in Nevada this is one of the methods they use to test the authenticity of your payout chip.
