Set on the island home of the legendary King Kong, Forgotten Island Megaways is a well-designed, atmospheric game with fast-moving, ever-changing gameplay where the special features provide a range of opportunities for big wins, particularly when the Rolling Reels and multipliers kick in. When combined with wilds and scatter symbols as well, there is always plenty of action happening, making this a highly engaging slot for players at all levels.

You can explore the legend that is Kong for yourself and play Forgotten Island Megaways at any of our recommended UK slot sites.

How to play  

Forgotten Island Megaways features 6 reels and up to 7 rows on reels 1 and 6, and 6 rows on reels 2, 3 ,4 and 5. There is also an extra reel consisting of 4 symbols which spin horizontally rather than vertically, located at the top of the main set of reels. The configuration of the reels changes with every spin, and the game can have as many as 117,649 ways-to-win in play at any one time.

20 coins are in play on every spin, and bets range in size from £0.20 to £20. Wins pay left to right in any adjacent combination, and trigger the Rolling Reels feature, where the symbols in a winning combination all disappear from the reels to be replaced by new reels rolling down from above, potentially creating multiple wins from a single spin.

  • Compass symbol is the Wild, and only appears on the extra reel
  • Wild substitutes for all other symbols except the Scatter
  • Kong symbol is the Scatter
  • Hitting 4x or more Scatter symbols anywhere on the reels triggers the Free Spins Bonus Feature
  • Hitting 6x Skull symbols = 50x total bet (up to £1,000)
  • Hitting 6x Book symbols = 5x total bet (up to £100)
  • Hitting 6x Lantern symbols = 2.5x total bet (up to £50)
  • Hitting 6x Grappling Hook symbols = 2x total bet (up to £40)


The maximum payout from a single spin on Forgotten Island Megaways is 7,000x total bet (£140,000 when betting the max). The biggest single payline win during base play is £1,000 for hitting 6x Skull symbols when playing the maximum coin size.

Forgotten Island Megaways is a very high volatility game, with a 96.25% RTP.

Special features

Kong Spin Feature

The Kong Spin Feature can be randomly activated on any spin, when Kong comes to life and awards a win multiplier of 2x, 3x, 5x or 10x. Each subsequent Rolling Reels win increases the multiplier 1x, and there is no upper limit as to how large the multiplier can grow. The free spins bonus round can also be activated when the Kong Spin Feature is in play.

Free Spins Bonus Feature

The Free Spins Bonus Feature is triggered by hitting 4x or more Scatter symbols anywhere on the reels. 10 free spins with a 2x multiplier are automatically awarded, with an additional 2 free spins awarded for every Scatter symbol on the extra reel.

During the free spins, the Scatter only appears on the extra reel, and each Rolling Reels win increases the multiplier 1x (with no upper limit). Hitting 3x or 4x Scatter symbols on the extra reel during the free spins awards an additional 3 or 4 free spins respectively.

Graphics and Sounds

Like all All41 Studios slots, the design of Forgotten Island Megaways is full of intricate detail, using a subtle blend of greens and blues (which changes to fiery oranges and reds during the free spins) with highly effective animations on every winning spin.

Throughout the game, Kong keeps a watchful eye over the reels, rearing up on his legs and beating his chest when the Kong Spin Feature comes into play.

The game has a throbbing soundtrack underneath the action, with drums beating constantly in the background, punctuated by pan pipes and jungle sounds. The tempo and intensity then steps up during the free spins, all of which contributes to the game’s dark, brooding atmosphere.


First released in January 2021, Forgotten Island Megaways is an excellent introduction for anyone who hasn’t played All41 Studios slots before. It showcases their high production values, including the first-rate use of sound effects and music, as well as the imaginative approach to gameplay.

Like all Megaways slots, there is plenty of action on the screen, although ultimately this is the sort of game that will probably be most appreciated by those who enjoy high variance slots where patience is required; however, there are ultimately ample rewards on offer when the Rolling Reels feature and multipliers come into play, especially during the free spins bonus round.

If you want to hunt down Kong and capture the big rewards on offer, you can play Forgotten Island Megaways at any of our recommended UK slot sites.
