Big Thunder Slots Review (updated December, 2023)

Ainsworth software providers are the masterminds behind Big Thunder Slot. This game has 5x3 reels, 20 fixed paylines and an over-the-average RTP of 96.27%. The fantastic slot has incredible features that range from free spins to wild multipliers and even a jackpot bonus round.

Set on jungle themed reels, this slot will remind you of King Kong and Tarzan all at once in almost a combination of the existing classics mashed into one slot theme. While the design and music might not seem so original, the gameplay hits high notes and delivers unique perks that’ll keep you glued to your screen.

Players can kick off their real gambling experience by playing Big Thunder free mode at Sir Slot.

- Under average RTP
- Theme feels unoriginal

Theme And Graphics

Big Thunder Slot has a jungle theme that reminds players of Peter Jackson’s King Kong movie. The strong silverback gorilla is the king of the jungle and, in this case, the king of the reels. As soon as you load up this game, you’ll see exactly what we mean about the theme being almost a mash-up with elements of different popular jungle characters in play.

Great Jungle Theme

The jungle theme will always have a place in casino lobbies. It’s a popular theme with developers as it allows plenty of potential for creating immersive backdrops, fantastic soundtracks and unique symbols that bring the theme to life. Big Thunder is an excellent example of this. 

Beautiful Setting

The beautiful reels are set deep in the rainforest, immersed in broad-leaved and dense plants, with trailing vines for the reel frame. A parchment colour forms the background of the reels, which makes the symbols stand out.

Big Thunder RTP And Volatility

The Big Thunder Slot RTP is 94.38%, which means that the game pays 94.38% of the total stakes paid in or £94.38. No real money casino games have payouts over 100%. The top games are card titles like poker and blackjack, which can payout over 98-99%+ on average.

Big Thunder Slot is a high volatility game. High volatile games don’t pay out frequently, and players have to spin the reels for long before a big win arrives. Players who get lucky receive generous wins that keep them motivated.

How To Play Big Thunder

Big Thunder Slot has an intuitive design. It has 30 variable paylines. Start by deciding how many lines you want to play per spin; it’s always best to go for the max if you can afford it and make the most of each spin. 

Use the slider to adjust the amount of the line bet. A Total Bet window located at the bottom right-hand corner of the screen helps players know how much they pay per spin. All wins are highlighted, and the amount is displayed at the bottom of the screen before being added to your balance.

Activate the autoplay by clicking on the + button, sitting alongside the spin button. A pop-up menu appears displaying a slider, beneath which are three grey buttons. The switch located on the left allows you to set a loss or win limit and the middle button sets the number of spins.

The Paytable

The game’s paytable displays the potential amount you can win based on your current stake. To access the paytable, locate the “i” button at the far bottom left of the screen. Then, familiarise yourself with the payouts and how to win Big Thunder Slot game.

How To Win At Big Thunder

Players have to spin three or more matching symbols across an active payline to win cash prizes on the reels of Big Thunder. The first instance of the symbol has to occur on the first reel, followed by further matching characters landing on consecutive reels along a payline. 

Winning lines are shown, with the amount won displayed in the main window at the bottom of the screen before adding to the player’s total balance.

The wild symbol helps players spin up the winning lines. It is easier to hit some winning combinations as the gorilla wild replaces most symbols found at the reels, apart from the Scatter, King Strike, and Multiplier symbols - these have more important functions.

Big Thunder Special Features and Free Games

Big Thunder Slot offers a great selection of added-value features that create a more exciting game to play. Ainsworth has ensured that the slot gives extra chances to help players scoop some huge prizes while having fun in the bonus rounds.

Wild Symbol

The wild gorilla symbol can sub for other symbols except a scatter, King Strike or Multiplier symbols. The game’s gorilla wild does not have a value in the base game, but when the free spins appear, two occurrences of the wild gorilla can generate a win. 

Scatter Symbol

The scatter symbol picked is the game logo. When players spin three or more at any position on the reels, they are awarded a generous prize. This is great as scatters do not always pay. In this title, they deliver the largest cash payouts in the whole game and trigger the bonus spins.

Free Spins

Three or more scatters trigger the Big Thunder Slots free spins bonus round. When the lightning flashes and thunder roars, players automatically know that a total of 15 free games are on the way. 

You’ll be taken deep into the jungle to play on a new set of reels. All lower-paying symbols are deleted. The slot gains an extra reel, too, but the sixth reel only contains three symbols:

  •   A Scatter
  •  A 3x Multiplier
  •   A 5x Multiplier

The remarkable thing about Big Thunder Slot is that when players get three or more scatters, they gain five more free games added to their total.

Big Thunder King Strike Feature

While playing the base game of Big Thunder, a small sixth reel is attached to the right-hand side of the game. Newbies might get a bit confused, but there is nothing to worry about. The small sixth reel is the King Strike Reel (also featured in titles like Jade Emperor or Electric Nights).

Besides the software developers A logo, the King Strike crown icon is the only symbol on the bonus reel. The symbol becomes relevant when slot players achieve a five-of-a-kind across an active payline.

Four jackpots are displayed as the Major, Maxi, Minor, and Mini sums at the top of the screen. The amounts indicated are dependent on the amount staked. It is easy to spot the amount when changing the sum you would like to wager with each spin:

  • The mini award pays out when gamblers hit a King Strike icon at the same time when spinning up five-of-a-kind of one of the lower-value playing card symbols in a combo and includes a wild.
  • Landing a five-of-a-kind win with high-paying symbols, including a wild, triggers the Minor Jackpot.
  • The Maxi Jackpot payout is achieved when players line up five-of-a-kind low-value playing card symbols and the King Strike symbol without the aid of a Wild.
  • Getting the Major Jackpot prize which stands at up to 1,000,000, is achieved by spinning up five matching high-value icons without the help of the Wild.
