Which Online Slot Machines Pay The Best

Best Paying Video Slots of 2020. Monopoly Big Event; 99,00% RTP. My absolute tip if you are looking for the best paying video slots is Monopoly Big Event by Barcrest (powered by SG. Mega Joker; Classic Slot with a high RTP. Joker Strike; Hi Roller Spins. Blood Suckers; High 98,00%.

Every slot machine that you play at an online casino has their own Return to Player (RTP) percentages. The RTP determines the odds of making a profit during a session. The higher the RTP, the less of an edge the house has over you. In short, with a higher RTP percentage, you stand a better chance of making a profit.

Return to player – Understanding payouts

The minimum percentage is usually 85%, but a solid payback percentage is between 95% and 97%. Keep in mind that slot machines with higher bet denominations also come with higher percentages for payouts. But be aware, if you come across a slot machine with a very high RTP (+98%), you probably can’t trust it. Legal and verified online slot machines have a maximum RTP of 97%. Anything higher is unlikely to be legal or appear on trusted sites.

Online slot machines that pay the most

Out of the hundreds of online slot machines, some are of course more profitable than others. In general, a reliable online casino advertises its most profitable slot machines. After taking a closer look, we distinguished two kinds of machines; video slots and progressive slots. Video slots have the highest payout rates. The best performing casino sites have pay-to-player percentages that can be as high as 97%. By contrast, progressive slots can win you the most money, but with a lower Return to Player. Our experts conclude that video slots are the preferred choice because you can win more often and there are still huge jackpots.

Rock On – 97.00%

Rock On is most likely to be the least popular game on this list, primarily due to its software provider. Developed by Rival Gaming, this title does not enjoy the largest player base, but then again not many gamblers have been exposed to it. Regardless, it is still worth talking about.

Showcasing a rock concert, Rock On looks like it came from the earlier years of the online gambling industry. The graphics are silly and cartoonish, but devoid of their charm. Rock On includes 5 reels and 20 paylines, as well as good betting limits. You can wager up to 10 coins per line, each with a value of up to $0.25.

In terms of gameplay, you will find no lack of features. The Wild symbol takes the form a guitar and while it does not have its own individual paytable, it does double the winnings from any combination in which it participates. Moreover, it can also expand to cover the whole reel in Wild symbols. The Scatter can trigger 10 free spins with a multiplier of x3, provided that you hit 3 or more of that symbol anywhere on the reels. The Elvis Bonus symbol is the key to triggering the bonus round.

Which Online Slot Machines Pay The Best

Rival Gaming has made some excellent titles in the past and it is a crying shame that many of them have not gained the recognition that they deserve. Rock On is a prime example of that. Not only does it offer all important features for a slot game, but it also comes with a great RTP value of 97%. There isn’t much more to ask for and we recommend that you try a few spins on Rock On when you come across it.

Mega Joker is the last addition to our list and arguably the game with the highest RTP in the current online gambling industry.

Which Online Slot Machines Pay The Best Buy

What is striking about this game is how it includes 2 sets of 3 reels. The symbols in the game are mostly fruits, with the odd joker thrown in there for a good mix. Mega Joker is an interesting title as it is practically a casual player and high roller game mixed into one. This is where the two sets of reels come in. When you first start the game, you will be placing regular bets of up to 10 coins on the bottom set of reels. Once you score a win, you will have two options. One is to cash in your winnings and continue spinning the same reels. The other is to move your funds to the Supermeter, where the payouts are 10 times higher but the minimum bet starts at 20 coins and goes up to 100 coins per spin. If you choose to move your winnings to the Supermeter, you can play as long as you have funds or until you choose to collect them back to your primary bankroll. It is worth noting that the above-stated RTP counts only when you play with 10 coins on the bottom reels and the Supermeter.
