Game information


Riddle of the Sphinx


Red Tiger Gaming









Riddle of the Sphinx is a Red Tiger Gaming slot with 5 reels, 4 rows, and 20 paylines. The theme is classic Egyptian. Many see the ancient Egyptian theme as a black sheep or mercenary no one likes. Yet, real money slots studios roll a bunch of them out every year. Or, a lost aesthetic that shines like a sturdy piece of antique with a bit of polish on it.

To help you catch those big wins. Riddle of the Sphinx packs it in with a Dynasty Wild and the Free Spins features.

Riddle of the Sphinx teleports you to an age where the pharaohs reigned supreme. The max win is a jackpot of 8,000x, and the volatility borders on the extreme. In fact, it clocks a 9/10 on the Whizz’s slots scale. If you want to join the fun on the reels you can do so from $0.10 to $10 per spin at mobile casinos online.


RTP & Symbols

The RTP of Riddle of the Sphinx is 95.66% is slightly below that of the industry’s 96% average. Is the RTP fair? Not really because the maximum cash prize is $80,000. Nolimit City’s 3 El Paso Gunfight xNudge trumps is not only with its jackpot of 44,400x but with its RTP of 96.06% too.

Looking for a payout? You need 3 or more matching symbols on the reels from left to right. However, you only need two high-value symbols for a cash prize. The symbols on the reels are the low-value card suits from 10 to Ace. The high-value symbols reflect the theme they are the scarabs, ankhs, Pharaoh Wilds, and hieroglyphs.

For a five-of-a-kind, you’ll pocket between 15x and 50x your stake. The Pharaoh Wilds substitute adjacent symbols for a win. If you’re from the United States of America Riddle of the Sphinx is not available to you. Slot machines like Jungle Stripes and Spring Wilds now feature in the libraries of our legal USA casinos online.


Bonus Rounds

Dynasty Wild

Stay on the lookout for Pharaoh Wilds. They come as 1×2 symbols and substitute for other pay symbols in winning combos. Not only that, but they also work for the Dynasty Wild Feature. In other words, they turn adjacent symbols into extra Wilds when they land!

Free Spins

You’ll trigger the Free Spins Feature when the Pharaoh Free Spins symbols pitch on reels 1, 3, and 5. An aspect about the pharaoh wilds we like is that they stick to the reels whenever they land.

Once you trigger the feature, you’ll have 4 options to choose from. Suffice to say that there are 4 combinations of free spins and Multiplier Wilds. Now, the maximum number of free spins is 24 free spins with 2x Multiplier Wilds. Shortly on its heels are 12 free spins with 4x Multiplier Wilds.

The other options are 6 free spins with 8x Multiplier Wilds or the Mystery Pick. That one blows hot and cold and can give you any combination from the aforementioned trio. Get lucky with it and you’ll get 24 free spins with 8x Multiplier Wilds!


Riddle of the Sphinx Tips & Strategy

We had a bit of fun when we played the Riddle of the Sphinx slot. Granted a bankroll of $100 at an average bet of $1 is by no means a proper assessment. Some players play the slots in the free mode for days on end before they deposit real money.

The base game flowed nicely and we collected some reasonable payouts. Nothing big, even though we triggered the Dynasty Wild Feature a few times. Let’s say that we weren’t lucky with high-paying symbols, only low-paying ones. The biggest base game win that we received was $20, so 4x our stake.

In our 100 spins, we triggered the Free Spins Feature twice. First, we went for the most daring option of 6 free spins with 8x Multiplier Wilds. Not much luck there since we only won $10. The second time around, we took another big risk with the Mystery Pick. The combo we got was 24 free spins and 4x Multiplier Wilds. Here, we got lucky for a payout of $40.



Riddle of the Sphinx combines good graphics with above-average bonus rounds. We liked the Dynasty Wild Feature and the Free Spins picks are fun. One thing we learned during our play is that Riddle of the Sphinx doesn’t suffer fools lightly.

Yes, the potential for the big wins is there, like most slots. The problem however is the RTP dampens the mood and a jackpot of 8,000x won’t rope in the high-rollers. Keep in mind, Red Tiger Gaming caps it with a max bet of $10.

Riddle of the Sphinx is less rewarding over the long term than Booming Games’, Sphinx Fortune Hold and Win. Even though the slot’s RTP is more or less on an even keel. Its jackpot of 8,500x is bigger and the bonus rounds more rewarding. Therefore, play is a lot less fiddly as the slot gets down to business straight away.
