JACKPOT HANDPAY! Rumble Thunder Slot Video - AWESOME Session, SUPER SWEET!
The Rumble Thunder slot machine by Ainsworth is similar to Rumble Rumble!
In fact, I consider Rumble Thunder a "Super-Charged" version of Rumble Rumble! Both Rumble Rumble and Rumble Thunder offer the "Sweet Zone" feature which can transform either single or multiple reels wild. There are two Sweet Zones, located in the middle row of reels two and four and if the Sweet Zone symbol lands in either, reels 1 thru 3 turns wild or reels 3 thru 5 turns wilds, depending on which one you hit. If you land both, then you will fill the screen with wilds for the top award!
This is exactly like Rumble Rumble, so what's the difference? The Payouts! In Rumble Thunder, landing both Sweet Zones pays out a whopping 250x your bet during standard games. Of course, this will occur less frequently than in Rumble Rumble, but when it does, you have an awesome Big Win on your hands.
Like Rumble Rumble, the bonus is triggered by landing 3 or more bonus symbols to award 8 free games and now here's the second difference: the expanded bonus play field has an increased number of lines, from 50 in the standard game to 150 in the bonus game, if your base game is the 50 line version of the game. I believe there are 30 and 40 line versions of Rumble Thunder so your total lines will triple, in any case. And here's the best part: your line bet remains the same as it did in your base game! This can be confusing, but the net result is landing both Sweet Zones during the bonus will award you a huge 750x win.
Of course, there's a price to be paid for these awesome Sweet Zone payouts. Sweet Zone hits are going to occur less frequently in both the base game and bonus game and while retriggers are possible, you need three bonus symbols to retrigger versus just two in Rumble Rumble. Scatter win payouts upon bonus trigger are also reduced.
Finally, the pay table for the base game and the bonus game remains the same in Rumble Thunder and compliments to the designer for simplifying the game by doing so as it can be really confusing when base game versus bonus game payouts radically change for what appear to be the same symbol hits. All in all, Rumble Thunder is a great game for those who want more volatility with the chance for that Big Win or Jackpot, Enjoy!
