Are the odds of Gamble Features Fair

We often see people describe the odds of card games found on the gamble feature as 4-1 when picking the exact suit of the next card that comes out of the pack. However, when you break down the amount paid back for the bet, the odds are in fact 3-1, which makes it fair for both the player and slot.

In fact, this is not a conjectured figure touted by the slot developers themselves or online casino operators to trick us – after all they don’t need to as they already earn a fortune

It is in fact a mistake that is quite easy to make, and it is often made by casino reviewers and a mistake that many of, including myself, have made because it easily done, and easy to miss the facts unless you look closely. Something we are all guilty of!

 ‘One of the main points out more strategically minded players mentioned was the mistaken odds that come with the gamble feature

Gamble features come with very fair odds and swing neither in favour of the slot or the player. If the game is a coin flip, then the flip is 50/50, so you win some and you lose some as you would with any coin flip.

The card games that come with bonus features are also very fair. You either pick the colour being red or black, once again giving you a fifty/fifty chance of winning, or you can choose the suit of the next card, which gives you a fair 3-1 chance as there are 4 colours to choose from.

To state the obvious, but in fact sometimes not the so obvious, it is not 4-1 odds for picking the correct suit, because with 4-1 odds, you would get your money back plus 4

As you have picked 1 card suit out of 4 suits to choose from, there is only a 3 in 4 chance of the machine winning. To oversimplify this we need to delve into some maths. You are offered quadruple you winnings; therefore, $100 would pay $400.

Now at 4-1 odds a bet of $100 that wins will pay back $400 prize money and your $100 bet also returned, so a $500 return with a $400 profit.

In a bonus game on a slot, you are only offered a total finishing prize amount of 4 times the amount of winnings risked. That means if you had $100 to go into the gamble with, you would win $400 as this is 4 times the value of $100.

Is this fair?

Yes totally. If we break it down another way, then it makes total sense.

There are 4 colours to choose from and 13 of each colour. All we need is the 4 colours as this is our bet.

You take 1 suit and the slot has the other 3 suits to win. Your chance of winning are therefore 1 in 3 translated fairly as 3-1. With $100 paid for your card, avoiding the other 3 cards is worth $100 each. The result is that you get $100 back per card avoided and your $100 back for hitting your suited card – a total payout of $400.
There you have it!
