Any smart gambler is always on the lookout for the slot machines with the best odds. Everyone wants to play games which give them the best chance of winning, and the best value for money.
In this article, we’ll go through the very best online slot machines based on their Return to Player (RTP). RTP is the average payout expected from a video slot over time. A 95% RTP tell us that on average that machine will pay out $95 in every $100 wagered.
But remember, that number is only an average, there is no guarantee that these slots will deliver the advertised RTP every time you play them. That would be very boring. Some will experience a winning RTP much greater than 100%, whilst others will experience an RTP lower than the advertised value. That’s the luck (or bad luck) or playing online slots.

Top slot game tips
Now you know the biggest-paying slot games out there, it’s time to focus on how to reach those jackpots. Here’s a few things to bear in mind before you start spinning.
- Pay attention to the game’s volatility. A slot’s volatility, or variance, should always be taken into account when choosing a game. This is considered the risk level of a game – low volatility slots payout often in smaller amounts, whereas high volatility slots pay out less often, in bigger amounts.
- Check reviews. One of the best things you can do before you start spinning is check the reviews of your chosen game. If a slot doesn’t payout, other players will have noticed and called it out online.
- Don’t go for the obvious choice. It’s not always the big, high profile games that are the best to play. Check the paytable of any game before giving it a spin – it may hold some surprises. And, of course, always check the RTP before you spend any money.
