Slot games have been one of the most popular gambling titles at Ireland’s top casinos for a long time now, and their popularity has only increased with the development of online casinos. Slots are also the only game type where the Return to Player (RTP) rate — the proportion of wagers a slot will pay out over its lifetime — is explicitly stated. Meanwhile, the frequency with which these slots pay out, along with the size of those payouts, is determined by something called the variance, or volatility. For a full breakdown of what this means for slots players, along with tips on selecting the right slots for you, read on for our guide and top casino recommendations.

FAQs
-
Low variance slots do pay out at more frequent rates than high variance slots, but that does not mean they should be seen as guaranteed wins. Gambling is at its core a form of entertainment and not a viable way to make a profit, so low variance slots should not be treated as such. What’s more, gambling companies have to make a profit in order to stay in business, so it is unlikely that you will be able to land many significant wins from a low variance slot.
-
Of course. Mobile gameplay is at the forefront of a lot of what online casinos do nowadays and so pretty much every bonus offered by an online site can be claimed on a mobile device. Some casinos may even offer mobile-specific bonuses so you would do well to keep an eye out for those if and when they appear.
-
Just like high and low variance slots, you can also come across medium variance slots. These games are a good middle ground, paying out larger prizes than low volatility slots at a greater frequency than high variance games. These titles are a good next step for players who have started out at low variance slots and want to move to the next level, although it’s worth noting that these kinds of slots are harder to identify than their low and high variance brethren.
-
Unlike the RTP, software providers are not legally required to share the variance of a slot. As such, there are a number of different tactics you can use to ascertain the payout frequency. Reading various slot forums is a great place to find out both the volatility of a slot as well as the general quality of it, while the paytable can give you a solid understanding how much a slot will payout for certain combinations. But, at the end of the day, the best way for you to work out the volatility of a slot is to play it and get a feel for it yourself.
