Rock On – 97.00%
Rock On is likely 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 few gamblers have been exposed to it. Regardless, it is still worth discussing.
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 not devoid of charm. Rock On includes 5 reels and 20 paylines, as well as solid 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 of a guitar and, while it does not have its own paytable, it doubles the winnings from any combination in which it participates. Moreover, it can also expand to cover the entire reel in Wild symbols. The Scatter can trigger 10 free spins with a multiplier of 3x when you hit three or more of these symbols anywhere on the reels. The Elvis Bonus symbol is the key to activating the bonus round.
Rival Gaming has produced excellent titles in the past, and it is a shame that many have not gained the recognition they deserve. Rock On is a prime example. Not only does it offer all of the important features for a slot game, but it also comes with a great RTP 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.

With a generous RTP of 97.50%, Hot Ink stands as one of the fairest casino titles out there.
As far as gameplay features are concerned, Hot Ink includes staples like Wild and Scatter symbols, multipliers, and free spins. There are also more interesting options such as the Respin function. Whenever you spin an undesirable result, you have the opportunity to re-spin selected reels at an additional cost. This feature can come in handy when you are one symbol away from a large win. Additionally, there is a bonus game to consider. Spinning three or more Tattoo Bonus symbols will trigger it, and you will be able to pick tattoos to earn cash rewards; completing a set grants you free spins with a multiplier.

Esqueleto Explosivo – 97.60%
Inspired by the renowned Mexican Day of the Dead, Esqueleto Explosivo offers players a fun and exciting game. Much like many modern slots, it features 5 reels with 17 paylines. Betting options are generous, allowing up to one coin on each of the 17 paylines, each with a maximum value of $100. As for the RTP, you will find the 97.60% rate well above the genre average, which satisfies many gamblers.
Gameplay features are abundant, and you will no doubt be pleased with what Thunderkick has included. Explosivo Wilds replace traditional Wilds; when one lands, it blows up surrounding symbols and applies a multiplier to any winnings. This multiplier ranges from 2x to 32x, allowing you to score excellent wins under the right conditions. Finally, we come to the Dropping Symbols feature. When you score a win, the winning symbols are replaced with those above, allowing you to potentially score additional winning combinations.

Up to 10 coins can be wagered per payline, with a maximum value of $1.00 each, which makes for a max bet of $50.
Immediately, you will notice that Kings of Chicago uses traditional playing cards as its symbols, and the combinations you form are classic poker hands ranging from three of a kind to a natural royal flush. The natural royal flush is the highest-paying combination in the game, rewarding you with 10,000 coins. The Wild symbol takes the form of a Joker card and can stand in for any other symbol on the reels. Scatters are also available, though they are awarded randomly and do not have their own symbol.
Spinning three or more Scatters at once rewards you with two free spins, or, as they are called in this game, Free Deals. They also apply a 2x multiplier to any winnings, and landing three more Scatters awards additional Free Deals.
Kings of Chicago masterfully blurs the line between video poker and video slots, providing a one-of-a-kind experience. It is exactly what we would expect from an experienced and renowned software provider like NetEnt, and the high 97.80% RTP makes this title especially worthwhile.

Money Cart 2 – 98.00%
For those seeking high-paying slots, we can also suggest Money Cart 2 by Relax Gaming. With an RTP of 98%, this video slot promises a generous return to lucky players who decide to spin its five reels. As the hold-and-win feature of the original Money Cart proved hugely successful, Relax Gaming launched this sequel that focuses solely on that mechanic. Consequently, there is no standard base game; winnings are awarded only when Money Cart 2’s special feature is triggered.
The game spreads across a grid with five reels and four rows, and the bonus feature can add two extra reels. Instead of paylines or ways to win, the slot pays whenever three Bonus symbols land anywhere. The value of each Bonus symbol is random: the standard Bonus icon carries between 1 and 10 coins, while the Gold Bonus symbol awards between 20 and 200 coins.
When three Bonus icons land, their cumulative value is added to your win, and the re-spin feature is activated. Each re-spin game starts with three bonus spins, during which special symbols can land and add to the total win. If new Bonus symbols land, the spin counter resets to three. When a reel is fully covered in special symbols, an additional reel is revealed, for a maximum of two extra reels. The bonus feature can award up to 50,000x the bet, making Money Cart 2 a superb option for players chasing bigger wins.

The reels are adorned with various items related to vampire lore, including garlic, stakes, spell books, potions, and vampire characters.
There are several special symbols in this game, including Wilds, Scatters, and Bonus icons. Wilds can substitute for any standard symbol, while three Vampire Bride Scatters trigger 10 free spins with a 3x multiplier. The Bat and Sledgehammer symbols serve as Bonus icons, and landing three of them initiates the bonus game.

One of the recent additions to the Habanero portfolio, Mighty Medusa has earned its spot among the high-paying video slots on our list. Like other titles from the provider, Mighty Medusa is offered with different RTP rates, but online casinos that choose the highest setting provide an RTP of 98.09%. This version lets players revel in a fun battle against Medusa and stack up generous payouts along the way.
The slot features six reels, offering players 466 different ways to win. Low-paying symbols award wins when they land on at least four adjacent reels starting from the leftmost reel, while high-value symbols pay even when matched only three times. You can also complete winning combinations with the help of Wilds, and certain symbol combinations trigger the bonus features of Mighty Medusa.
When Perseus and Medusa symbols land on adjacent reels, the Medusa Duel feature starts, turning a random symbol Wild. Meanwhile, three or more Scatters anywhere on the reels activate the Free Games feature, with a 2×2 Medusa Wild in the center of the slot’s grid. Any Perseus symbol that lands during the Free Games feature is turned into a Wild, and it can also trigger Medusa Duel when adjacent to Medusa. A random 2×2 Pegasus symbol may appear during bonus spins. As you can see, Mighty Medusa can deliver very generous payouts to those lucky enough to unlock its bonus features.

Joker Strike is an interesting video slot from Quickspin that embraces the style of old-school games. The base gameplay comes with a lower RTP of approximately 96%. The 98.11% rate applies to the Hi Roller feature, which you can activate at any point during play.
This feature is iconic for the game and can lead to large wins. There are three levels of the Hi Roller feature, each with a different cost: $20, $30, or $50 for five spins. Depending on the level you choose, you gain guaranteed Wild symbols placed randomly on the reels. The more expensive the spins, the more valuable the Wild interactions become.
We also have to mention the Joker Strike feature for which the game is named. Around the reels is a secondary track. The feature adds symbols to the reels if the outer marker stops on the same symbol displayed on the track. Under the right circumstances, you can add up to 10 extra symbols to the reels. This feature is available in both the base game and Hi Roller mode.

Marching Legions – 98.12%
We also recommend another Relax Gaming slot to players seeking better payouts: Marching Legions. The slot boasts an RTP of 98.12%, far higher than the average return most slots offer. The game uses a grid with 5 reels, and symbols align in winning combinations from left to right. Marching Legions provides 243 ways to win, rather than requiring symbols on specific lines.
This Roman-themed slot has high volatility, meaning players may endure several losing rounds before landing generous payouts. The legionaries are the key symbols, as they can trigger several features. Whenever a full stack of legionaries lands on a reel, a re-spin is activated, potentially bringing extra payouts.
The Nudge feature may trigger when two or more partially stacked legionary reels appear, pushing them to cover their reels fully and triggering re-spins. The slot also has a Collection feature linked to the legionary symbols. Once enough symbols are collected, players activate the Free Spins feature. Those who lack the patience to trigger bonus spins naturally can also buy the feature and play with free spins immediately.

Book of 99 can be generous in its base game, but it can reveal even greater rewards through its special features. The Wild symbol helps complete combinations and is collected each time it appears. Once 99 Wilds have been collected, or when three Wilds land on the reels, the Free Spins feature is triggered. During this bonus game, free spins play with a special expanding symbol that pays even when symbols aren’t connected from left to right.

Mega Joker – 99.00%
Mega Joker is the final addition to our list and arguably the game with the highest RTP in the current online gambling industry. Standing at 99%, you will be hard-pressed to find a slot with a better payout percentage. Developed by NetEnt, it emulates classic fruit machines while adding a modern twist to the gameplay.
What stands out is the game’s two sets of 3 reels. The symbols are mostly fruits, with a joker for variety. Mega Joker is both a casual-player and high-roller game in one. When you start, you place regular bets of up to 10 coins on the bottom reels. After a win, you have two options: cash out and continue on the same reels, or move your winnings to the Supermeter, where payouts are 10 times higher but the minimum bet starts at 20 coins and goes up to 100 coins per spin. If you choose the Supermeter, you can play until your balance depletes or until you collect the funds back to your primary bankroll. Note that the 99% RTP applies only when you play with 10 coins on the bottom reels and use the Supermeter.

Ugga Bugga – 99.07%
Ugga Bugga by Playtech is sure to intrigue players, especially when they learn about its RTP of 99.07%, a rate that is hard to beat among classic or video slots. Ugga Bugga is quite unusual, sporting a distinctive design and gameplay.
Instead of multiple reels and paylines, Ugga Bugga consists of ten separate sections, each representing a payline. Every payline has three reels, awarding different payouts for various symbol matches. Each wager launches two spins. The initial spin reveals three symbols in one section. Players may hold one, two, or all of these symbols, which are then copied to the remaining sections and held for the second spin. This setup allows for multiple wins across all ten sections.
The slot will appeal to players who prefer smaller bets, as wagers range between $0.10 and $50 per round. You can bet between one and five coins per spin, but we recommend the maximum stake because only five-coin wagers qualify for the top win of 1,000x per section. That also enables the overall maximum win of 10,000x the line bet if all 10 sections hit the top payout.
