King Kong is a video slot experience created by the provider Nextgen Gaming. In this King Kong slot review you’ll learn about its core features (including RTP, max win, and volatility), the bonus mechanics, and what helps the game stand out — along with the areas where it may fall short.
King Kong is played on a 5 reel layout with up to 25 paylines/ways. The game includes a variety of features such as Bonus Game, Bonus Multiplier, Expanding Wilds, Extra Wilds, Mystery Prize, Pick Bonus, Retrigger, Scatter Pays, and more. There’s also a dedicated free spins bonus round, which is typically where the game’s biggest win potential comes into play.
The standard RTP (Return to Player) for King Kong slot is 95.14% (Could be lower on some sites). This payback is good and considered to be about average for an online slot. Theoretically, this means that for every €100 put into the game, the expected payout would be €95.14. However, the RTP is calculated on millions of spins, which means that the output for each spin is always random.
The highest possible payout for this slot is 3750x your total bet which is pretty high and gives you the chance to win quite big wins. The maximum possible win is also calculated over a huge amount of spins, often one billion spins.
