High variance slots explained

As any experienced slot player will know, the machines are programmed in such a way that over its lifetime it will keep a certain percentage as profit with the balance returned to the players.

For a slot machine that is set at 97%, if it is programmed to spin 250,000 times at £1 a spin, it is set to make a profit of £7,500 with the remainder of £242,500 returned to the player.

The machine can distribute the winnings any which it likes.

I have programmed an example here:


The page “plays” 2,500 sessions at 100 spins each session. No matter how many times you refresh the page, the end result will be the same – a loss of £7,500.

During game play, at times the player may be up. At times it shows a large loss with the next session of 100 spins turning into an overall profit only for it to result in a loss at the end of the 250,000 spins.

The key to playing any slot machine is to know when to walk away. Temptation when you’re in profit is to continue playing but in reality you’re better off walking away and pocketing the money.

On the other hand, when you’re at a big loss, theoretically speaking the machine should turn and return some of your losses. But that may depend on your bank roll. Are you prepared to invest even more money and potentially throw good money after bad?

There are no tricks to playing slot machines. At the end of the day it is down to good old luck whether the machine is in a giving or taking mood.

Make sure you set yourself a loss target and know when you’re prepared to pocket a profit. As long as you stick to these simple rules, you can’t go wrong and make playing slot machines an enjoyable hobby that potentially could be a profitable one.
