Understanding slots: most of them work like this, 80-90% of the time you get nothing, 10-20% of the time you get a random small amount of money, and 0.1-1% of the time you hit a 'bonus round' which can pay out huge amounts.

Some good days have a lot of offers going on and you can get +200, and some days can be quieter. I usually spend about 2-3 hours per evening just clicking on the spin wheels and counting how many times I've done it. Now there are many, many +EV offers which you can do every day, you can smash them all out in a couple hours, £1 EV here, £5 EV there, even 20p ones are worth doing, since they only take a minute to do. So this example which I gave was a +90p EV offer. So 19+1.90=20.90 you have just gained 90p of 'expected value' (EV) Now the real world results are always going to vary, you could've gained much more than 90p profit or lost the whole £20, no matter what the results were, you gained your EV, which means you spent your money where YOU had the edge. free spins are usually worth 10p each, and 20 of them would (on average) expect to get you £1.90. This is the most important thing to understand. But as you see the house always has the 5% edge.īUT when you are doing special offers, (e.g spend £20 get 20 free spins) then it is YOU who has the 'house edge'. There will be highs and lows, but over a long time of averages, you will get 95% back. You can of course spend only 10p on a slot and get a £1000 win sometimes, or you can spend £100 and expect to get around 95 back, but actually end up getting only like £5 back. Roulette is 97% RTP, Blackjack is 99%) whatever the game is, the 'House edge' is usually a few percent which is how the casinos make their money. For example 'spend £20 on x slot game to receive 20 free spins' and let's say x slot game is 95% RTP (this means Return To Player, which means if you spend £100 on the slot, you should on average get £95 back. Basically there are 100s of casino sites, and many of them give you special offers, which can be done daily or weekly, or whenever they show up. I guess the thing which puts people off, is that it's not GUARANTEED profit every time. So if you have a basic understanding of math, it should be easy to understand.
