Use of computer vision to analyze slot machines?

Is anyone aware of any use of computer vision to analyze or reverse engineer slot machines? It seems like it would be relatively easy to use a phone to track game results.

I understand that it would not be wise to start working on something now as video is on the way out thanks to various scams and illegal activities, but has anyone done this or know of any projects that have done it?

Phones are powerful enough to track outcomes, throw them in a database, and analyze as someone plays. It would not even require play in some cases. Youtube videos for property specific products would suffice.

Is this happening?

The newer slots are more of a mirage than actual reels spinning. Phones can only record so many frames per second and the reels may be spinning faster than that. If you want to pinpoint one slot reel pattern before playing a credit before a winning one, you might be able to vulture a slot machine, but there's many of the same symbols on each reel, so it seems to be a fool's errand.

I seem to recall a Russian group that used phones to somehow determine when the player should hit the spin button to have a higher than normal hit rate on a particular group of older slot machines.

I don’t recall if it was discussed here or not.

That was due to an alleged issue in seeds that allowed for results of RNG to be predicted. A signal would let person know when to hit the button to increase chances of a big win. I have my doubts as the difference between RNG refresh rates and human reaction time is so large. Would it really be possible to find clumps big enough to change your return? I say I do not think it would possibly.

I am referring to straight use of video to figure out what games are paying and work out the math behind them based on what is shown at the end of each game. Nothing crooked.

To be technical, it was not the initial seed of the pRNG that they were able to guess. They reverse-engineered the software and were able to predict the complete sequence of games the pRNG would make available. Then, by sampling some results and knowing the fairly precise timing of these results, they could say with some certainty where they were in that time sequence. That allowed them to synch up with the pRNG sequence. Knowing the clock rate, they could predict when clusters of games were coming with above average RTP. They could then spin only during these +EV fluctuations.

Newer games have faster clocks, so this requires more precision. However, new games also have such enormous bonus rounds that they can result in a fairly large number of games having a average +EV.

yes this is happening ... a guy on here he may or may not pop in if he sees this ill try to find his thread and post it here

Is there a way to work this without running afoul of "Device Law"?

Thanks for this, best explanation of the Russian hack method that I've seen.

Yes, I believe those were mainly on the Aristocrat Mark IV machines. When those were made they were not required to run the RNG constantly. Or, if they were running it it was so slow it could be timed.

Another fine play that doesn't suit my personal idiom. Swell!
