When ready, you may follow the guide below to help you get started:

  • Log in to your King Casino account.

  • Press the Casino Chip button on the main page to place your stake.
  • Press the 3-bar Menu button to open the paytable and view the game’s rules.

Winning combinations form by landing 3 or more matching symbols on the paylines, starting from the leftmost reel to the right.

The Action Boost Amber Island slot game contains low and high-paying symbols depicted by animals, insects and playing cards.

The highest-paying regular symbol is the black panther, awarding up to 5x your stake for a 5-of-a-kind combination. However, this payout potential is surpassed by the special Wild symbol, which could award up to 10x your stake for a 5-of-a-kind combination.

Wild Symbol

The Wild symbol is the flaming woman. It can land anywhere on the reels in both the bonus and the base game. If it lands on potentially winning combinations, it can help you complete the combination by replacing other regular paying symbols. 

It’s also possible to create a winning combination with only Wild symbols on a payline:

  • 3 Wilds = 1x your stake
  • 4 Wilds = 2x your stake
  • 5 Wilds = 10x your stake

Additionally, the Wild symbol can appear stacked on the 4 rows.

Random Reveal Symbol

The Random Reveal symbol is a black lava stone. It can land on any spin, revealing a random regular paying symbol if it lands. The Random Reveal symbol can also reveal gems during the base game and a volcano during the Action Boost Extra Spins game. 

Action Boost Extra Spins Feature

Gem symbols (Green, Red, or Purple gems) can only appear if revealed by the Reveal symbol. Each time at least one gem lands, there is a possibility of triggering the Action Boost Extra Spins feature. Above the reels are volcanoes that the Gem symbols will be collected into if they are revealed. 

Then, if you trigger the Action Boost Extra Spins feature, the type of Action Boost Extra Spins feature you receive depends on the type of gems that triggered the feature. 

Green Gem Action Boost – award 5 Extra Spins. If the Random Reveal symbol reveals a volcano, it awards a credit bonus prize. The reels expand to accommodate up to 6 symbols, and the paylines increase to 40. If you land a Wild symbol, it is nudged so that the entire reel has Wild symbols. 

Red Gem Action Boost – award 10 Extra Spins. If the Random Reveal symbol reveals a volcano, you will be awarded jewel symbols or a credit bonus prize. The jewels can award the following Jackpots:

  • Mini Jackpot triggers by collecting 3 green jewels = 10x your stake
  • Minor Jackpot triggers by collecting 4 blue jewels = 50x your stake
  • Major Jackpot triggers by collecting 5 purple jewels = 500x your stake
  • Mega Jackpot triggers by collecting 6 red jewels = 5,000x your stake

Purple Gem Action Boost – awards 5 Extra Spins. Revealing the volcano symbol awards 1 or 2 Extra Spins or a bonus credit prize. On every spin, a random multiplier of x2, x3 or x5 is awarded.

Return To Player

Return to Player (RTP): 96.37%

RTP is used to explain the potential money that an online slot or casino game can pay back to players. It appears as a percentage and is generally calculated from gameplay over a long duration of time.

For example, if a slot has a RTP of 97% this means that it could pay back £97 for every £100 wagered.

However, there is no guarantee that players will receive this amount, as slot payouts are entirely random.
