Top 6 slot games with highest RTP in 2023

There are various options to explore when it comes to playing online slots. For example, some gamblers may choose to play slot machines based on their themes or features, while others prefer high RTP online slots. 

An online slot game’s RTP directly influences its potential profitability, so the higher the RTP, the better. Of course, a game’s RTP might vary depending on where you play, but the best online slot sites offer fair percentages. If you’re set to boost your winning possibilities, read on as we explore six online slot games with the highest RTP in 2023.

1. MEGA JOKER – Up to 99% RTP

NetEnt’s Mega Joker slot game has become popular for its super high return to player percentage. The RTP for a one-coin wager is a surprising 76.9%. However, a maximum bet of 10 coins raises the RTP between 89.1% and 99%. 

The Supermeter mode and higher payments are two additional perks in this slot. When playing in Supermeter mode, you can choose your wager level and the maximum level at which you can claim a win. Enhancing the RTP is totally up to you and your betting style. Mega Joker is a fan favourite because of the game’s classic aesthetic and fun gameplay.

2. JACKPOT 6000 – 98.8% RTP

Amongst the slot games with the highest RTPs in 2023, Jackpot 6000 claims the second spot. Powered by NetEnt, Jackpot 6000 is a classic slot machine with a retro feel. With up to five active paylines and bets ranging from one to ten coins every spin, you have plenty of options. 

In order to activate the Supermeter mode, it is recommendable to play with the maximum stake of 10 coins. You can earn between 10 and 6000 coins in this game mode if just two joker symbols appear anywhere on the reels.

It’s also worth noting that in Supermeter mode, getting three jokers on a payline assures a 6000-coin jackpot. The RTP is between 74.9% – 79.2% when playing Jackpot 6000 with 1 – 8 coins. However, it varies from 95.1% to 98.8% when playing with ten coins. The variance can be attributed to the Supermeter mode being more skill-based.

3. 1429 UNCHARTED SEAS – 98.6% RTP

Powered by Thunderkick, the 1429 Uncharted Seas slot machine features five reels and 25 paylines. Also, you may play from 10p a spin on any device to explore the depths of the oceans. It has a cult appeal because of its RTP of 98.5%. 

A hand-drawn map in medieval style has replaced the reels, and the icons include sea animals, beasts, and the sun, moon, and stars. In addition, this slot features an expanding wild symbol to increase your chances of landing a huge win. Up to 50 free games are also available in a free spins bonus.


On the 4th spot is another thrilling slot game from NetEnt. This creepy offering is based on the vampire genre, which has never been more popular. On the reels, you’ll witness a variety of Blood Suckers and the weapons needed to combat them. 

Even though this slot has an RTP of 98%, it isn’t the only thing that attracts players. All included free spins with triple rewards, wild substitutions, scatter wins, and a bonus game involving vampire slaughter. You’ll find yourself in an ancient coffin-filled burial room after triggering the bonus. Each time you kill a vampire by opening their coffin, you’ll get coins.

5. STARMANIA – 97.87% RTP

Colourful star symbols and atmospheric soundtrack make this NextGen slot a visual treat and a sonic one. Wilds are stacked on each other, increasing your chances of winning.

If you have a line win, you can also wager your winnings for a chance to multiply your money by two, four, or even eight. Starmania is a huge hit with players because of its fantastic graphics, engaging features, and favourable RTP of 97.87%.


As a hybrid of video slot and poker, Kings of Chicago is a unique experience. Cards are used in the game, which is shuffled before every round of play. As opposed to typical slot machines, in this one, you win if you manage to form the five-card poker hand on one of the five paylines. 

A joker card is included in the game, which can be used to replace any other card. In addition, any card may bear the scatter label. Getting at least three of them, you’ll receive free deals, which are essentially free spins. So, for example, you could win up to 30 free deals in the bonus round, and your winnings doubled.
