Gamble Feature

Found on close to half of the slot machines out there, the gamble feature allows you to go double or nothing with your winnings, and in many cases you can win 3x or 4x more than you did on the base game. How this feature operates changes from game to game, but many of them take on a similar theme.


The most common gamble feature makes use of an old card game known as Hi-Lo. Basically, there is a single card on display, and your goal is to gamble on whether the next card drawn will be higher or lower. There is always an Evens chance when the card shown is an 8, so more often than not you will also be asked to bet on whether the card will be black or red, whether it will be a spade, heart, diamond or club, or even what number it will be. As the risk increases and the odds decrease, then your winning potential will increase. Not all gamble features allow for anything more than a simple Hi-Lo, but these additions are being found more and more on newer slots.

How to Use

You should never gamble more than you’re prepared to lose, assuming that a 50/50 chance is enough of a risk considering the reward on offer. If you’re happy with your winnings, then leave the gamble feature alone. If not, if you secured a win that was less than your stake or one that is not in the least bit impressive, then you can use this feature. After all, in such cases you won’t care if you lose but will be happy if you win. The smaller the initial win, the bigger risk you should look to take, always having your eye on a decent return.


This is a tightly regulated industry, but unfortunately, that doesn’t always lead to fair games. We have personal experience of this. On the Castle Builder slot on the William Hill site, we encountered a bonus round where were asked to take a chance on three different returns. This was supposed to be random, with each option returning odds of 3/1 However, for 15 choices in a row, we ended up with the lowest paying one. And the only reason this didn’t extend to 16 and beyond is because we stopped playing. The odds of this happening for real are in the millions to one, which suggests the game was rigged to return the lowest amount.

There has also been a similar issue with a gamble feature. This happened on the BetFred casino software, with players discovering that a feature that was supposed to offer odds of 50/50, was actually heavily weighted in favour of the house. Luckily, this was reported, BetFred changed providers and that software is no longer there, but the fact that it was there in the first place is enough of a reason to be wary of such features. Don’t ignore them altogether, but remember that your odds might not always be as described.
