Kaiju slot REVIEW

Kaiju ReviewKaiju is a futuristic and well-designed slot from ELK Studios, and it comes with up to 7776 ways to win. It was launched 22 February 2018, to the delight of all fans of Japanese monster movies and japanese culture in general. The backstory is elaborate, and the main attraction is the Free Spins feature in which you get to battle a chosen Kaiju with lasers. This is a highly volatile slot from ELK, and you can win up to 1305 times your stake on this game.

Kaiju RTP, variance & technical data

Before we take a closer look at all the fun features on Kaiju slot, we thought it would be a good idea to reveal the game’s most relevant technical data for you:

RTP: 96.3%

Volatility/Variance: High

Layout: 5x3

Paylines: Up to 7776

Bonus features: Free spins, Sticky wilds and Expanding reels

Bets: 0.2 to 100

Max wins (coins): 130 400

Kaiju has a pretty standard RTP of 96.3%, although it’s a tad above the industry average of 96%, which is always positive. Return to Player is a theoretical number that indicates how much you can expect the game to pay out in the long run. Kaiju is also a highly volatile slot, which means you should be prepared for fluctuations on your bankroll, and adjust your bet level accordingly.

For those unfamiliar with Japanese culture, a Kaiju is a Godzilla size monster and these kind of monster movies are simply called Kaiju movies in Japan. In this game the monsters grow large and heavy gem stones on their scaly skin, and what’s left of humanity in this dystopian world are in desperate need of these Kaiju crystals to survive.

Of course, harvesting these precious stones from the Kaiju’s skin is far from an easy task, and in truth, humanity's only hope rests with the female Cyborg, HA-42, and her many special abilities powered by a compact nuclear reactor.

The Kaiju’s get mighty mad when someone tries to steal their skin crystals, but HA-42 is fast enough to get away with it. As you might understand, the backstory is somewhat important when playing Kaiju slot, and anyone into Japanese movies and culture should absolutely love this game.

The game itself has 5 transparent reels, and is set on a backdrop of a dark and seemingly deserted futuristic city. The symbols are Kaiju crystals and credit cards of different colors. Vertical lasers will give you random wilds, and the Kaiju Battle Free Spins are undoubtedly the main attraction to be found here. The reels can expand up to 7776 paylines, and you can win as much as 130 400 coins on Kaiju.

Kaiju bonus features

The Vertical Laser feature will reveal wilds on the row above your winning combinations, and this gives you extra chances to create even more winning combos. This is the only bonus feature in the main game, but the free spins feature we shall discuss below is really what it’s all about.

Kaiju battle free spins

The Kaiju Battle Free Spins is the main feature of the game, and it’s triggered when you land 3 Cyborg HA-42 symbols on reels 2, 3 and 4 at the same time. This immediately rewards you with 7 free spins, and a random Kaiju opponent is then chosen from the green, red and blue crystals.

Each Kaiju is unique in the sense that they have different hot spots that the vertical lasers needs to activate, and you’ll find these on the 3 rows above the reels. The vertical lasers will give you wilds, and also expand the reels upwards. The expansions of the reels will remain throughout the free spins feature, and each expansion gives you 1 extra free spin.

To beat the Kaiju you have to activate all the hot spots with the vertical lasers, and the last hot spot activated will turn the winning symbols into sticky wilds applied to the remaining free spins. This means that you can win some rather decent payouts in this feature, and it’s always exciting to see how far you can take it.

Kaiju jackpot (max win)

There is no progressive jackpot to be won on Kaiju slot, but you can certainly win some nice payouts even so. The max win is 1305 times your stake, or 130 440 coins. Not the highest maximum payout we’ve seen relative to the high variance, but still not too bad.

Kaiju mobile & tablet

ELK Studios certainly prioritizes the mobile experience for all their games, and Kaiju looks amazing on any mobile platform. Be advised that portrait mode is the recommended display for this game, and it’s a great slot to bring with you wherever you may go. Play on your Android device, or on your iPhone and iPad - whatever suits you the best.

SlotCatalog verdict

While you might need a little patience to trigger the Kaiju Battle Free Spins feature, it’s very much worth it once it happens. This is quite a nod from ELK to a popular japanese cult class of movies, and we’re certain a lot of Westerners will appreciate it also.

We wouldn’t mind even more features in the main game to make it more entertaining, but you cannot always get everything you ask for. All in all, this game is targeting a niche audience, and the elaborate backstory, great soundtrack and futuristic graphics goes a long way.


Great futuristic design and backstory
