Slot overview
Ainsworth Big Thunder Slot Overview
It all began here when Ainsworth, the popular game developer, launched this Big Thunder franchise in 2016. The jungle is dense and still safe from the touch of modern civilization. Ainsworth had astounding success from Big Thunder that urged it to come up with its sequels too.
Big Thunder falls under the animal theme, and Ainsworth has quite a handful of titles to show as proof of expertise. Look for titles such as Pussy Cat, Run with the Wolves, Fortune Falcon, and more.
Check out Big Thunder, the 5-reel, 30-pay line slot where there are chances of coming across interesting bonus rounds and rewards. The free online slot game to play now is definitely worth your time.
How to Play the Big Thunder Slot Game
When the reel opens, you see the dense foliage staring at you and giving you a sneak peek of what to expect from this video slot. Bet from €0.01 and go up to €100. Enjoy varieties of bonus offers the game promises after you start spinning the reels.
The free casino slot machine to play online is enjoyable at every step. The Autoplay option is worthy of trying, and you can set it from 5, 10, 15, 20 to 25. This would give you an easy time as the reels spin. 
Big Thunder Slot Machine Features
- Authentic Layout and Design: As creators of one of the best free slot games to play online, developers have stuck to the game theme and design. The symbols also match the jungle and tribal style.
- Special Symbols: The gorilla is wild in the base paytable and substitutes all symbols except the scatter. In the base paytable, the Big Thunder logo is a scatter. It pays well too, as much as €15.00 for matching 5 in a row.
In the feature paytable, we have the gorilla, which pays well from a minimum of €0.05 to €20. It also substitutes in the feature games. The scatter is the Big Thunder again, which pays as much as €60.00 for a maximum of 5.
- Other Symbols: These include snake, shield, mask, waterfall, and a bongo drum. There is also a King Strike crown symbol in the base game. On the other hand, we have the x3 and x5 multiplier symbols in the feature paytable instead of this symbol. There are no poker symbols in the feature paytable too.
Big Thunder Slot Game Bonus Rounds
If we look at it, the game begins when you start betting. It is just a matter of time before Gorilla wild comes on screen to substitute all except the King Strike crown and the scatters in the paid games. It comes only on reels 3, 4, and 5. The King Strike comes on reel 6 of the paid games. Scatter wins, and bonus wins are all added together.
Next to note is when you land 3 or more Big Thunder scatters. Get ready to begin the 15 Bonus Reel feature. Here, you can expect x3, x5, and the scatter to appear. The gorilla substitutes for all except these x3 and x5. If these multipliers appear anywhere, expect the wins to be multiplied by 3 or 5. Get 5 more Bonus Reel feature games to become active if you get 3 or more Big Thunder scatter. The bet lines will be the same as the game that activated this feature.
The next talking point bonus is the King Strike bonus. Here, you can get a Mini bonus if you get 5-of-a-kind of Nine, Ten, Jack, Queen, or King with at least one substitution in the winning formation along with King Strike on reel 6.
Get a Minor bonus when you have a 5-of-a-kind waterfall, drum, snake, shield, or mask with one substitution in the winning formation. King Strike should appear on reel 6. You will get a Maxi bonus if you have the 5-of-a-kind formation of poker cards without any substitution in the winning combination. The King Strike should come on reel 6.
The Major bonus is what you get when you have a 5-of-a-kind waterfall, drum, shield, snake, or mask. There may be no substitution in the winning combination, and the King Strike appears on reel 6.
Play Big Thunder with Real Money
What makes the Big Thunder real money slot to great heights is the presence of the King Strike feature. It is a big break from the regular free games or multipliers and is high on prizes.
