Kaiju Slot Details and Features

Kaiju is a five-reel, three-row slot with up to 7,776 ways to win. It has an epic sci-fi theme featuring gigantic creatures (the eponymous kaiju), a cyberpunk-infused future setting, and great bonuses.

The Kaiju casino slot opens with an amazing animated sequence that sets up the story and introduces the game’s star, the cyborg HA-42. This stylish intro gives Kaiju a more dramatic feel and personality than many other slots on the market. 

The gorgeous visuals continue in the game — everything from the background to the symbols looks fantastic. Even the ambient electronic music is impressive, reinforcing the game’s futuristic feel.

Game Symbols 

The symbols in the Kaiju mobile slot include three different types of crystal, one for each kaiju: a Red Crystal, a Blue Crystal, and a Green Crystal. They pay up to 300x, 200x, and 160x your bet, respectively.

Three glowing Card symbols feature, too, with colours matching the Crystals. The Red Card pays up to 150x your bet, the Blue Card pays up to 120x, and the Green Card pays up to 90x. There is a Wild and Bonus symbol to discover too — we’ll cover these later in our Kaiju online slot review.


ELK Studios’ Kaiju slot UK has a 96.3% RTP and high volatility. You can bet from 0.20 to 100 per spin. 

How To Play Kaiju

Kaiju Slot Bonus Features

Wild Symbol

Three identical symbols connected vertically during the base game will reveal a Wild on the row above them. 

Bonus Symbol

Find three Bonus symbols, featuring HA-42, to trigger the Kaiju Battle Bonus Game and win seven free spins.

Kaiju Battle Bonus Game

At the start of this awesome Kaiju slot bonus feature, you’ll have seven free spins, but you can get one more free spin for each reel expansion triggered. One of the three Kaiju, with an individual arrangement of Hot Spots on its body, will be randomly picked to be your opponent. 

The Vertical Laser is a key part of the Kaiju Battle Bonus. It can trigger three features:

  • Reel Expansion: Any matching symbols connected vertically from bottom to top will reveal a Wild and expand the reels. 
  • Hot Spot Activation: If a Vertical Laser activates a Hot Spot, all symbols on that vertical line will become Wilds to help you win. 
  • Sticky Wilds: If a Vertical Laser activates the final Hot Spot, symbols on that line will become Sticky Wilds. These will stay in place for the rest of your free spins.
