Looking for the Best Paying Slot Machines?
You can’t beat the feeling of winning a large jackpot from an online casino game like a slot machine. This page explains the difference between massive payout slot machines and slots with lower return to player (RTP) payout rates to help you choose the games that offer you best odds and jackpots.
How to Find the Best Payout Slots Online
There are a number of factors to keep in mind when looking online for the best payout slots. The first is the size of the jackpot. You’ll find the biggest prizes attached to progressive slots, because the more that people play, the faster the jackpot builds.
Set your sights on popular titles with a decent track record of rewarding five or six-figure prizes, rather than titles offering a huge prize that is only won every year or so.
Look at the slot machine’s return to player (RTP) percentage. This will tell you what the house edge is on the slot. For online slots, a RTP of 95% or higher is good.
It's also important to look at other aspects like the maximum stake. The best payout online slots tend to be those with the highest maximum stake, and in many cases you need to be betting the maximum to scoop the jackpot.
The number of paylines is also important. Some high paying games feature tons of paylines, sometimes over 1,000, which can lead to big wins for players prepared to cover all lines.
What is RTP?
RTP stands for return to player percentage. When applied to online slots, RTP is a figure that lets you to see the house edge on a particular game at a glance. For example, if the RTP is 95%, that means for every $100 you wager on that game, you can expect a return of $95 on average. Details of a game's RTP can be found in its paytable.
It’s also worth noting that the highest paying games tend to offer the lowest RTP. For example, the RTP of one of the world's most famous progressives, Mega Moolah, is 88%. When choosing which game to play, make sure to balance the prospect of a big win against the RTP first.
