Top Paying slots and jackpots

When choosing which online slot to play, the most important point to consider is whether you prefer to play high- or low-volatility games. You can expect a low- to the medium-volatility slot to have a payout percentage of around 95% or higher.

Progressive jackpot slots are high-volatility games which offer a payout percentage in the region of 87%. This lower payout rate means that there are fewer wins and so your average return is not likely to be as good, but this is offset by the fact that progressive slots offer the potential for truly enormous jackpots, very often in the millions of dollars.

Ultimately, the sort of game that you choose to play depends on your approach to playing—would you prefer a higher average return, or would you rather fewer wins for the chance of a life-changing jackpot. Whatever sort of game you decide to play, this page will guide you in finding the right sort of online slot to suit your particular playing style.

Most frequent jackpots

Progressive Slots


You can choose one of two routes when selecting an online slot to play: either low- to medium-volatility games with higher payout percentages and smaller, albeit still significant, wins; or high volatility progressive jackpot games that offer wins on an enormous scale, but with a lower payout percentage rate, and therefore fewer winning spins.

Your choice will depend on the way you want to play, but it’s important to undertake some research before you begin so that you’re making a conscious and well-informed decision.
