Big Thunder Bonus Features

After playing the game for quite some time, I found 3 bonus features, Free Spins, Wild, and Scatter Symbol.

Let’s look in more detail at how this slot operates:

  • Hand

    Free Spins:

    The free spins bonus round  is triggered by three or more scatter symbols. 15 free spins will be given to you in total, and they will be played on a different set of reels as lightning and thunder rumble. You will also be taken further into the jungle during this time.

  • Hand

    Wild Symbol:

    The game’s gorilla Wild Symbol substitutes for all other symbols on the reels except for the scatter.

  • Hand

    Scatter Symbol:

    This game’s scatter is the Big Thunder slots game logo, and if you spin up three or more of these anywhere on the reels, you’ll be given a large cash reward.

Storyline, Graphics, and Sound 

Big Thunder

Tha game features a huge silverback gorilla as the king of the jungle. The game takes place deep beneath the rainforest. Broad-leaved plants cover the woodland floor while trailing vines hold the game’s reels in place.

You won’t miss any possible winning lines because of the reels’ parchment-colored background, which makes the symbols truly shine.

RTP and Variance

The game is classed as a high-volatility game, thus it doesn’t pay out very regularly. Its RTP is below average at 94.38%.

Gameplay and Bet Sizes 

Set a time restriction and a session budget that allows you to play Big Thunder responsibly, no matter how much fun you’re having playing the game online.

Starting up in the online version of this game couldn’t be simpler:

  • Pick from low, medium, or high risk. When you play this slot for real money, the stakes can be adjusted to match your comfort level with risk.
  • Pick between a manual bet and an automatic one, with autoplay options.
  • To modify your wager per drop, use the minimum, maximum, plus, and minus buttons.
  • You may play with 30 lines, so pick your bet size and let the reels spin!

The reels are arranged in a standard 5×3 grid with 30 paylines. You may spin the reels of the slot machine for as little as 0.3 to 3000 credits every turn.

How To Win At Big Thunder

To receive a cash payout on the Big Thunder, you must line up three or more identical symbols along a payline that is now active. The symbol must appear just once, and any more matching symbols must appear on succeeding reels in accordance with the appropriate payline arrangement.

The game will do all the legwork for you, so don’t bother about checking the reels after every spin to see if you won or lost. Winning lines are highlighted, and the winnings are added to your balance before being shown in the primary area at the bottom of your screen.

There is a wild symbol to assist you in spinning up winning lines. Except for the scatter, king strike, and multiplier symbols, the gorilla wild substitutes for the majority of the other symbols on the reels, making it easier than you may expect to make some winning combos.
