Krakatoa Design

After loading the game, you will have an apocalyptic scene of the island devastated by lava spreading all around it. On the reels, you will see the card royals styled in fire lines crossing them. There are a toucan bird, a lizard and another reptile. Part of the game takes also the local god along with images of buildings and logos. The graphics are inspired by the island and its volcanoes, fiery and blazing of lava. The images are clear, colourful and precise. This is a high volatility game with an RTP of 96.43%.

Krakatoa Gameplay

The symbols taking part in the game are low-value card royals and higher-rewarding picture icons. These are wilds animals, buildings, and some others. You will see a toucan, a lizard and another reptile. There are cash reward icons and fixed jackpot ones too. The “FREE GAMES”-marked icons is the scatter which returns your stake when you land 6 of it in a single spin. There is a bonus symbol that activates the bonus game.

The wild is an erupting volcano with the word “WILD” written in green on it. As usual, this is a substituting symbol for the other regular ones helping you score more and better-paying wins. This symbol you can see landing on reels 3, 4 and 5 only. During the base game, you can score wins up to 600 times your stake. This you can do from winning symbols and paying combinations.

The bonus feature in the slot is called Lucky Break. You activate it with 6 or more of the bonus symbols landed in one spin anywhere on the reels. Then, the reels will start spinning many times. They will be landing symbols with fixed cash prizes displayed on the icons. The best one has a value of 200x stake. Through this feature, you can win one of the fixed jackpots as well. These are:

  • Mini Jackpot – worth £30
  • Minor Jackpot – worth £120
  • Maxi Jackpot – worth £600
  • Major Jackpot – worth £1,500
  • Grand Jackpot – worth £15,000

You can get extra spins from the Lucky Break bonus feature by landing the relevant symbols: +1, +2, or +3 Free Games.

Krakatoa Features & Bonuses

To win the Free Spins you have to land 6 or more of the Free Games scatter symbols in one spin. You will be rewarded with 1 free spin for each triggering scatter. This is what determines the number of your free rounds you will have initially. The free games you will play with wild symbols landing on the last 4 reels. Also, multiplier wilds will boost your payouts, which you can get on the 3rd reel only. The multiplier wilds can have the values of 2x or 3x at random. They can help you turn a top win of £7,200 into £21,600 thanks to the 3x boost.

The Conclusion

Krakatoa is a unique slot with a topic that isn’t very popular nowadays or used in the creation of video slots. Its features ensure good chances for wins. This is thanks to the bonus game with fixed jackpots and the free spins with wild multipliers. In the base game, the max cash prize is 600 times your stake. While in the free spins it can be 3 times as much from the wild multiplier boost – £21,600.

The 5 fixed jackpots let you grab from £30 to £15,000 according to your luck. Being a high variance video slot, Krakatoa may not suit all high rollers due to its modest top rewards. Even though, the design and features are entertaining and deserve your attention. Wait for the slot’s release and try it in free mode first before playing for real.
