Big Thunder Slot Machine – RTP, Features: Review

Big Thunder is based on a famous silverback gorilla that lives in the tropical jungles. The 5-reel game has a total of 30 paylines, with a low volatility in terms of winning spin frequency. And just because the game pays out more often than not doesn’t mean the game isn’t worth playing, because there is a special bonus reel that offers the chance to win one of four jackpots.

If you’re simply playing Big Thunder in demo mode for pleasure, the topic of RTP and volatility is unlikely to come up. However, if you intend to play the games for real money at an online casino, you must first ensure that the game is fair, reputable, and offers an acceptable amount of risk for your playing style.

The RTP for Big Thunder is 94.38%, which indicates that for every 100.00 spent on spinning the reels, the game pays out 94.38 dollars.

Big Thunder King Features

You’ll encounter four jackpots in the main game of Big Thunder: Major, Maxi, Minor, and Mini cash amounts. As you can see when you adjust the amount you’d want to gamble with each spin, the quantities presented are depending on the amount of your stake.

When you get a King Strike icon and five-of-a-kind of one of the lower-value playing card symbols across an active payline, the Mini reward is paid out, and a Wild icon helps to make up the difference. You will be awarded the Minor Jackpot if you spin the King Strike image with five matching higher-value symbols, one of which is swapped by a gorilla Wild.

  • To win a 500x line bet reward, discover five 9, 10, J, Q, K, or A symbols with at least one wild symbol.
  • Minor game bonuses: earn a 1,000x line bet reward if you discover five mask, drum, snake, waterfall, or shield icons with at least one wild.
  • To win a 2,500x line bet reward, discover five 9, 10, J, Q, K, or A symbols.
  • Find five mask, drum, snake, waterfall, or shield symbols for a chance to win a 10,000x line bet reward.

Big Thunder Slot Strategy

To win a cash reward on the Big Thunder reels, you have to spin three or more matching symbols across an active payline.

That is, providing you go on to play the game for real money at an online casino, because all balances, winnings, and losses on our website are completely imaginary.

The symbol must appear on the first reel, with more matching symbols showing on subsequent reels in accordance with the payline layout. But don’t worry about scanning the reels after each spin to see whether you’ve won; the game will do all the legwork for you.

Matching five high-value icons, as well as the King Strike symbol, will award you the Major Jackpot prize, which could be worth up to $1,000,000.00. When you line up five-of-a-kind low-value playing card symbols, plus the King Strike symbol, without using a Wild, the payouts increase. You’ll get the Maxi Jackpot reward if this happens.
