Image of Best RTG Slots to Play

Realtime Gaming (RTG) is an online casino provider primarily focused on video slots. The company was founded in 1998 and is currently based in Costa Rica. RTG has a rich and diverse portfolio of over 200 slots, and you can run into the studio’s best titles on casino sites in over 40 countries. 

This article will focus on some of RTG’s best slots, specifically the ones with the biggest payout potential.

Spirit of the Inca

Software RTG
Slot Type Video Slot
Progressive No
Bonus features Free Spins, Bonus Game, Jackpot, Wilds
RTP 91% – 97%

Spirit of the Inca is still one of RTG’s top-performing titles despite being released back in 2012. The game’s graphics hold up very well, with their quality matching even some of today’s releases.

There are several reasons for this game’s evergreen popularity, one of them being the big jackpot prizes. Namely, Spirit of the Inca has five Boiling Pot Jackpots — Mini, Minor, Major, Maxi, and Grand — with the Grand one potentially awarding hundreds of thousands of dollars.

All five jackpots are active only when playing with the maximum stake. The Grand jackpot won’t be available if you bet less than the maximum. Besides the progressive jackpot, the maximum payout is 50,000x bet per line.

Spirit of the Inca also has an engaging bonus game. Each time an expanding wild represented by an Incan warrior shows up on the first and last reel, the bonus game will trigger. Before it begins, you’ll get to select five squares from a grid.

The first three squares will reveal the number of free spins up to 25, the fourth square shows the prize multiplier during the free spins up to 10x, and the fifth square will either reveal a wild reel, an extra wild, or no bonus.

Spirit of the Inca has a 5×3 layout with 25 fixed paylines. The game has a variable RTP that ranges between 91% and 97%.

Slot Type Progressive Slot
Progressive Yes
Bonus features Free Spins, Megasaur Feature
RTP 91%, 95% and 97.5%

Megasaur is another RTG title known for its progressive jackpot. The jackpot size is continually above one million dollars, so it’s no wonder this is still one of the studio’s most popular releases.

To win the biggest prize, you must bet the maximum stake and hope that the five volcanoes appear on the reels. Four volcanoes will win you the Major jackpot (20% of the main jackpot prize), and three will award the Mini jackpot (10% of the main jackpot prize). The top non-jackpot prize in the game is 50,000 times the bet per line.

Three or more volcanoes also trigger the Megasaur Feature. Clicking on each volcano reveals how many free spins you’ve won, with up to 10 free spins per volcano. You can win additional free spins during the round itself. Once the feature is over, you may get the Win-Win bonus consisting of a prize worth 250 times your bet.

A great thing about Megasaur is that you don’t have to wait for ages to trigger the Megasaur Feature. The game comes with a Feature Guarantee, which ensures that the Megasaur Feature triggers within the given number of plays, namely between 26 and 250 spins.

Megasaur is a 5×3 slot with 25 fixed paylines. It comes in three RTP variations, including 91%, 95%, and 97.5%.

Aztec’s Treasure

Software RTG
Slot Type Progressive Slot
Progressive Yes
Bonus features Free Spins
RTP 95%

Realtime Gaming obviously has plenty of inspiration when creating slot games based on ancient American civilizations. Following the success of Spirit of the Inca, RTG released Aztec’s Treasure, which became an instant hit, and is still present across dozens of online casinos.

Aztec’s Treasure features a progressive jackpot. You can see the ever-increasing main prize at the top of the reels. It can be triggered randomly after every round, adding the sum to an existing win. Aside from the jackpot, the maximum win in Aztec’s Treasure is 50,000x the bet.

Meanwhile, three, four, or five idols appearing anywhere on the grid will result in 5, 15, or 25 free spins, respectively. You can win more free spins during the round, with even one or two idols awarding new spins. Also, each additional scatter that appears during the free spins round will award a prize equal to the bet that triggered the round. All prizes won during the free spins are tripled.

Aztec’s Treasure has five reels, three rows, and 20 fixed paylines. The game’s RTP is 95%.

Cleopatra’s Gold

Software RTG
Slot Type Progressive Slot
Progressive Yes
Bonus features Free Spins, Scatter Symbols, Wilds
RTP 95%

We’re going to round up this list with another high-paying progressive. This time, we’re moving away from South and Central America and going to North Africa to visit the pyramids and one of ancient Egypt’s most famous rulers.

In all honesty, Cleopatra’s Gold is an RTG slot with an overused theme and subpar visuals and sound effects. Nevertheless, many players still enjoy it due to its big payout potential.

Like Aztec’s Treasure, Cleopatra’s Gold features a progressive jackpot that triggers randomly and can be awarded at the end of any spin. The jackpot prize is usually several thousand dollars at any moment. When won, the jackpot prize is added to the wins resulting from the spin that triggered it.

Cleopatra is the game’s wild, while the pyramid is the scatter. Apart from substituting for all other symbols except the scatter, the wild also doubles every win when part of a winning combination.

Meanwhile, three or more scatters unlock 15 free spins, during which all wins get tripled. Three or more pyramids during the free spins round result in additional 15 spins.

Cleopatra’s Gold has 20 fixed paylines laid out on a 5×3 grid. This title should not be confused with Cleopatra Gold, an IGT slot that does not feature a progressive jackpot.
