Top 10 highest paying slot machines
1. Spooky 5000 (Leander): 99.21%
The best paying online slot machine is Spooky 5000 from Leander. Spooky 5000 is a combination between the old fruit cupboard and a creepy horror story. You play with the fantastic payout percentage of 99.21% if you play consistently with the Ghost Meter if that is possible.
2. Monopoly Big Event (Scientific Games): 99%
This sky-high payout percentage only applies if you play online on the Monopoly Big Event slot machine and then also with the Big Bets. This costs, but then you also have the excellent payout percentage of 98%. You can also play Monopoly Big Event without Big Bets, but with a payout percentage of 96%.
3. Mega Joker (NetEnt): up to 99%
One of the most played NetEnt slots is Mega Joker. Slot machines always do well, even on the internet. Mega Joker also has an amazingly high payout percentage. You have to play with 10 credits per spin and consistently use the Supermeter.
4. Jackpot 6000 (NetEnt) – 98.6%
Jackpot 6000 is also an online slot machine from NetEnt. The payout percentage of the Jackpot 6000 slot machine rises to a maximum of 98.9%. You have to play with the Supermeter when you can. Playing with the Supermeter is done with credits won. Each time you win, you must continue to play via the Supermeter.
5. 1429 Uncharted Seas (Thunderkick): 98,6%
Thunderkick takes you on a voyage of discovery on the 1429 Uncharted Seas castle. In the ship you make your way between mermaids and sea monsters. Prices often fall. 1429 Uncharted Seas not only has an extremely high payout percentage, this slot machine also has an extremely low variance. That means a lot of prizes, but not too high.
6. Dr. Jekyll Goes Wild (Scientific Games): 98.2%.
Dr Jekyll Goes Wild is, of course, inspired by the story of Dr Jekyll and Mr Hyde. After some unsuccessful tests in his laboratory, Jekyll turns into a ruthless bloodthirsty beast. Scientific Games has turned it into a very attractive online lock.
7. Blood Suckers (NetEnt): 98%
Blood Suckers is an almost perfect guest for wagering a casino bonus. That is, if the online casino allows it. Many casinos have excluded Blood Suckers from the bonus terms because it is almost a certainty that you will play your bonus with it. That’s how high the payout percentage is and that’s how low is the variance of this Blood Suckers slot machine. Blood Suckers is even more popular than the sequel, Blood Suckers II.
8. Kings of Chicago (NetEnt): 97.8%
A gameplay maverick is Kings of Chicago. The Kings of Chicago slot machine is a cross between video poker and an online slot. Video poker is one of the best paying casino games. The Kings of Chicago slot machine is hardly inferior to video poker. The idea is to play as valuable a poker hand as possible. Have you ever managed to spin a Royal Flush on a slot machine? Probably not. On Kings of Chicago it is possible. The Royal Flush is even the most lucrative combination.
9. Starmania (NextGen Gaming): 97.8%
Starmania does not have great graphics. Despite the somewhat simple star set theme, it doesn’t look like much. It looks like a simple computer game from a long time ago. And the bonus game? OpalRB wants to call it almost soporific. But what difference does it make? The power of Starmania is in very different things.
10. Devil’s Delight (NetEnt): 97.6%
Devil’s Delight is an old lady. Online slots are not made like that anymore. And that’s right too. The payout percentage of the Devil’s Delight slot machine is nice and high, namely 97.6%.
