Game Design

There is a slick, anime-inspired intro video that bears the words: “Humanity’s last refuge. This is my home. I am HA-42,” which is the name given to the fearsome protagonist who is tasked with taking down the Godzilla-styled monster that features in the slot game.

ELK Studios has designed the Kaiju slot to take place in the twilight surrounds of a far-future metropolis in which neon signs dazzle in the streets. The actual slot interface has made translucent, so as to let gamers see the city street in the background.

In terms of size, the Kaiju slot interface measures in at five reels by three rows to display 15 symbols at any one time. However, the special features will allow for the screen to be temporarily extended, but all of that will be explained below in this Kaiju slot review.

Wagering Rules

Kaiju does not have specific paylines, as the symbols have to be matched in adjacent reels. Therefore, the standard wagering is quite simple, with the total betting values ranging from £2.00 to £100.00. However, you can get more complex by choosing one of the pre-set betting strategies devised by ELK:

  • Optimiser: Betting changes automatically based on whether you assign the percentage of your total balance as 1%, 2%, 5%, or 10%.
  • Leveller: Betting increases by two levels after five losses, but resets after a win.
  • Booster: The bet raises one level after a loss until increasing by four levels.
  • Jumper: Your bet increases a level after every win until raised by four levels.

Winning Potential

Kaiju carries tremendous winning potential from the fact that the top jackpot measures in at an impressive 130,440 coins, while there are 7,776 ways to win. Here are some of the most valuable symbol multipliers when five are matched:

  • Red gem: 300x
  • Blue gem: 200x
  • Green gem: 160x

Bonus Features

The action shall grow even more intense if you are able to benefit from any of the bonus features that have been built in by ELK:

  • HA-42: Get three bonus symbols to start the Kaiju Battle with seven free spins.
  • Vertical Laser: Three vertically connected identical symbols shall trigger the appearance of a wild symbol on a reel created just above.
  • Kaiju Battle: A Kaiju will randomly appear and launch into battle. Vertically connected symbols shall lead to reel expansions, hotspots, and sticky wilds.

Strategy and Tips

You should only use the betting strategies if you can grasp how they function, as it’s important to always know how many spins you have left based on your current wagering value. Kaiju is more rewarding from the bonus features, so staying patient to unlock them is important.


Kaiju might seem like a silly concept at first, but it’s one that you will soon grow to appreciate as you begin to benefit from the likes of the Vertical Lasers or Kaiju Battles. These definitely rank higher than the base game symbols in terms of importance.
