Hot & Cold Slots

One of (if not THE) most popular phrases among slot casino guides is hot and cold slots. The idea that a particular slot is either hot or cold so you need to try and find a slot which is hot.

This advice shows a complete misunderstanding of the mechanics behind online casinos. We have already talked about the Random Number Generator in previous articles, if you have not read these yet then go and check them out.

There are plenty of casinos who actually have live indicators of hot and cold slots or even a special hot and cold section of the website (Royal Panda for example). These do not help you at all. If a slot has been “hot” over the past few minutes, hours, days that still tells you absolutely nothing about what will happen in the next session you would play on these slots. They all use the same RNG (Random Number Generator) so it is purely suspicion if you want to play a “hot” slot or a “cold” slot.

The whole myth of hot and cold streaks stems back to the classic physical fruit machines and slot machines found in pool halls, land casinos, cross channel ferries, pubs, etc. Yes, these really did have payout cycles. These old fruit machines were not as advanced as the video slots of today and they were indeed basically programmed to eat a few hundred pounds at a low RTP and then in a sequence of a dozen or so spins spill out a few jackpots in a row to get to the true programmed RTP. You could (and yes many times I did) sit around in a pub all evening, keeping an eye on the fruit machine in the corner and try and guesstimate how much money had gone in and come out. Plan your timing right and you could get a good profit out of the machines. The same happened in the fruit machine halls, play slow, cheap and casually for hours keeping your eyes peeled on all the fruity s around you and try and catch them just before they go into payout mode.

Now this just doesn’t happen any more. The random number generator takes care of that.


Having said all that, I for one have played way too many spins on online slots over the years, we are talking millions of spins here. And I do believe that sequence happen here too. It does depend on what slot you are playing and by which provider. NetEnt have recently actually altered the maths engine on their newest slots which I believe is going to see far fewer people being able to make any sort of guess as to what mood the RNG is in. But there are times when you can guess you are on a winning run. How often do you see a big win closely followed by another big win? On the flip side, how often do you do on a monster losing run?

The problem here is that a winning run on an online slot really doesn’t last very long at all. However losing runs can last for hours. So even for the most hardened online slot player it really is super difficult to read what is happening and any casino mentioning hot and cold slots are just telling you useless information. These are just the slots which have paid out particularly well or particularly badly over the last few minutes or hours.

Want to see a random number generator in action?

If you have Neteller, Skrill, Bitcoins, etc then I really hope you already have 2 factor authentication installed… if not then DO IT TODAY. You need to protect yourself from hackers, take it from me, my brother lost his whole Skrill account to a hacker and Skrill never reimbursed him.

Google Authentication is a random number generator you can watch in real time. Sometimes your random security code will make a huge jump from one number to the next… however very often you will only see incremental changes like 77xxxx to 76xxxxx to 80xxxxx to 91xxxxx etc etc. Just watch it go for a while. How random is this really? How does it work? What is the maths behind the number generation?

I also believe that the random number generators do not have a maximum value and a minimum, by which I mean it doesn’t see 999999 as the top number and 000000 as the bottom possible number. Watching Google Authentication often sees numbers 9xxxxx jump to 0xxxxx or vice versa. In this way you could say that after getting a massive win (99xxxxx) you could end up going on a losing run as the RNG has risen beyond the top level rather than having to go downwards again which would keep you in the money.

This is of course all speculation. Without seeing the complex code or seeing a numerical representation of the RNG for every spin over a long period of time then there’s no way I can know if I am correct in my assumptions or not. Pure speculation.
