Cobra King Slots

Cobra King Slots

Cobra King slots is an Arabian-themed game with 5 reels and 1,024 ways. Developed by Rival Gaming, it takes you into ancient Arabia, where princes, sultans, princesses, and genies dwell. Cobra King has a very Aladdin-like feeling along with detailed desert city in the background. Keep reading to learn about this game's graphics, features, betting options, RTP, and more.


Cobra King features 5 reels and 4 rows (5x4 grid), plus 1,024 ways to win. You create winning combinations by landing 3+ matching symbols in adjacent reels (starting with reel 1). Given the prevalence of 'ways' slots nowadays, you should have no trouble adjusting to this one.


This online slot opens with a mysterious sultan (a.k.a. Cobra Emperor) overlooking his kingdom. You'll then see an expansive Arabian city with a palace (left-hand side), towers, and buildings in the distance. Once the reels come up, you get a look at the main characters and objects (e.g., swords). The background graphics are excellent and really show the detail in the city. Cobra King's symbol graphics are okay, but they don't quite match the backdrop in terms of detail.

Symbols & Payouts

Regular symbols include royals (A-10), a cobra, feather, magic carpet, prince, princess, sword, tiger, and treasure chest. The treasure chest pays the most among this bunch at 75x the stake for five matching symbols. No maximum win for Cobra King is available in the info section.

This game offers three special symbols as well, including the Cobra Emperor, lamp, and genie. The Cobra Emperor is a wild symbol that can expand to fill its respective reel (a.k.a. expanding wild). The genie and lamp icons both come into play during the bonus round (covered next).

Cobra King Slots Features

You trigger 10, 15, or 20 free spins with three, four, or five scatter symbols (genie). One goal during free spins is to collect 15 genie lamps and advance to the next "Wish." The three available Wishes and their accompanying modifiers include:

  • Wish 1 - Expanding wild with 3x multiplier symbol
  • Wish 2 - Drop symbols with a 3x multiplier wild
  • Wish 3 - Sticky 3x wild with respins

Betting Options

The betting range starts at $0.30 and goes up to $75. You can adjust your bet size from $0.30 to $7.50, and your coins from 1-10. General gameplay options include turning the music on/off and adjusting the game speed (slow, medium, fast).

RTP & Volatility

The Cobra King slots RTP is 94.15%, which is pretty low compared to most online slots (generally 95.5%-96.0%). No volatility rating is available for this game, although we're guessing that it's medium or medium-to-high. We experienced plenty of wins during our Cobra King review, although nothing that was outstanding.

Play for Free

You don't need to bet anything just to try Cobra King slots. Instead, this game is available for free at Rival Gaming online casinos. We always suggest trying online slots to ensure that you like them before laying down real money. Our suggestion is no different for Cobra King, which is widely available for demo mode.

More on Rival Gaming

This slot isn't Rival Gaming's first foray into an Aladdin-style setting. It also developed Arabian Tales years ago, which has a similar storyline to Cobra King. So if you enjoy the latter, then you might give Arabian Tales a few spins too. As for Rival's other work, this developer has been designing online slots since 2006. It has produced many hit games for US-facing casinos during its tenure. Some hit Rival slots include Blazin' Buffalo, Catsino, Five Times Wins, Hot Hand, Viking Victory, and Vintage Vegas.

Verdict on Cobra King Slots

We give Cobra King slots an 8 out of 10 rating. This game offers an authentic atmosphere combined with a detailed bonus round. The "Wish" concept in the bonus really adds something unique that we haven't seen in similar games. Downsides include mediocre symbol graphics, low RTP, and no stated maximum win. Out of these, the low RTP is the biggest problem on our end. Nevertheless, we think that Cobra King is worth trying at least once for the feeling and Wish Free Spins alone.
