Big Thunder Free Slot

The slot is intense in its appearance and bets, with its vibrant setting and bright symbols. The mysterious fleshy, dark leaves of the forest foreshadow the grand entrance of the gorilla who rules the jungle. However, the slot is made distinctive with the tribal ornaments and weapons hidden in the jungle in the game. The symbols are gaudy and shining, fitting with the overall demeanor of the slot. The tribal ornaments and the jungle-based symbols act as regular multipliers with values of 1.3x, 1.7x, 2x, 2.5x, 3.3x, 5x, 6.7x, and 50x in the base game and 1.3x, 3x, 3.3x, 6.7x, 10x, 25x, 66.7x, 100x, and 200x in the bonus game. The game has 15+5 free bonus reels with x3 and x5 multipliers and consists of jackpots of Mini, Minor, Maxi, and Major levels with wins of 16.7x, 33.33x, 83.33x, and 333.33x respectively. The top win from the game is an exclusive 333.3x gained through the Major jackpot. However, the RTP of 94.38% is unusually below average and the high volatility cannot promise consistency of payouts. So, while operating at the top bet of $3,000, the RTP and variance would be a major risk, with rather slim chances of hitting the max win of 200x. Nothing to be disappointed. Collect treasures through the streaming waterfalls of the jungle in the Big Thunder demo game. Assortments of the most benefitting slots can be found from the same provider. Check out Prosperity Dragon with a bet range of $0.01-$10,000, or Jungle Monkeys with 20 free spins.

Bonus Features

The jackpot feature is a show-stealer but the bonus reels and King Strike are unique to the provider as well as rewarding.

Bonus Reel Feature

The Big Thunder scatter triggers 15 Bonus Reels that appear with 2 new bonus symbols, ‘x3’ and ‘x5’. Appearance of x3 on a bonus reel adds x3 to the winning amount and the appearance of x5 on a bonus reel adds x5 to the winning amount. An additional 5 bonus reels are added with 3 more scatters appearing on the payline.

King Strike Bonus

The Major and Minor jackpot bonuses are awarded with the occurrences of 5 high-paying symbols like the waterfall, power drum, shield, snake, or mask when a King Strike symbol appears on reel 6. The Maxi and Mini jackpot bonuses are awarded with the occurrences of 5 low-paying symbols like A, K, Q, J, 10, and 9 with the same King Strike symbol on reel 6. These bonuses occur only on Bonus Reels.

The Big Thunder real money game displays all the jackpots and grants them for real, accessible by players.

RTP and Payouts

The RTP of 94.38% is uncommonly low for a jackpot slot while the volatility is expectedly high. The high volatility is common but also risky for bigger payouts.

The card deck symbols 9, 10, J, Q, K, and A act as low-paying symbols with a range of 0.17x-2.5x for 3 - 5 occurrences. The power drum, waterfall, mask, shield, snake, gorilla, and Big Thunder scatter are high-paying symbols with a range of 0.33x-50x for 3 - 5 occurrences in the base game and a range of 0.17x-200x for 3 - 5 occurrences in the bonus game. The max bet of $3,000 is the max bet and the readings are taken on its basis. The Big Thunder free game presents the tribal and refreshing jungle symbol payouts for free.

Max Win and Top Multiplier

The slot exhibits a max win of 333.3x for the Major jackpot with a top regular multiplier of 200x for the bonus Big Thunder scatter.
