How to play

The core anatomy of Big Kahuna Slot is based around the following classic video slot mechanics:

  • Five reels
  • User selectable choice of between 1 and 9 paylines active per spin.
  • User selectable choice of between 1 and 5 coins bet per active payline.
  • User selectable choice of coin value between $0.05 and $2.00.

Staking: Getting in a spin is as simple as choosing how many paylines you’d like activated (the more in play the more opportunities that the next spin will produce a win), how many ‘coins’ you want to bet on each payline, and the coin value you want. Juggling these choices you can bet very flexibly from as little as $0.05 (one payline with one coin of $0.05 bet on it) up to a Max Bet of $90.00 with all nine paylines in play with five $2.00 coins bet on each!

Autoplay: Big Kahuna also features an Auto Play mode if you want to set up a sequence of up to one hundred games to play through automatically, and this is accessed by clicking its Expert button.


Whilst Big Kahuna can’t boast of a millionaire-making progressive jackpot, the headline prize from its paytable is a pretty pleasing 8000x your linebet if you land five of this online slots Wild symbol on an active payline. Putting that into cash terms, if your pockets are deep enough to place the maximum linebet of $10, a jackpot win on that line will land a whopping $80,000 prize.

Volatility: With regard to frequency of payouts Big Kahuna slot serves up wins pretty regularly with all nine paylines in play indicating a low to medium volatility.

Special features

  • Big Kahuna Wild – not only the top-paying symbol on the paytable, this can also substitute for any of the fruit symbols where that will generate a win.
  • Monkey Scatter – two or more of these in view triggers a payout of a multiplier applied to the total stake on that spin.
  • Volcano Bonus – Three or more instances of the Volcano symbol on an active payline triggers a second screen bonus game. In this game a player pick from five on-screen fruit reveals an instant cash bonus.
  • Pick A Mask Bonus – Three or more instances of the Tiki Mask symbol on an active payline triggers a second screen bonus game. In this game a player pick from ten on-screen masks reveals an instant cash bonus. The player can continue to pick masks, accumulating rewards until a mask reveals ‘Collect’ to end the game.

Mobile Version

Mobile Kahuna: Big Kahuna has also enjoyed a mobile makeover, putting it into your hands on any portable device’s web browser that can handle HTML5. The mobile version is identical to the desktop game, so if you love getting in a spin with Big Kahuna at home you won’t have to miss a thing when you go out and about with its mobile casino incarnation.

Graphics and Sounds

Big Kahuna is a slot of simple pleasures with bold, colourful symbols and an ambient backdrop of the sounds of nature in what we guess is a tropical rainforest! Symbol animation is a little basic when compared to some of Microgaming’s more recent releases, but the overall feel is of a classic casino machine that you would be delighted to play on a real-world gaming floor.

Closing paragraph

Big Kahuna slot won’t wow you with cutting-edge presentation or innovative bonus features, however that could well be its underlying charm. This is an online slot that sticks to the basics of classic video slot gaming, which is actually a recipe that works perfectly for many, many players judging by the continuing popularity of this game at the best online casinos. The bonus games are a little bland for our tastes – we’d have preferred to get Big Kahuna into a free spins frenzy – but this is a slot that brings wins with some regularity, and its headline jackpot is certainly worth sticking around for if very good luck erupts during a session.
