Rumble Rumble Slots Machine

Every year, the Running of the Bulls takes place in the city of Pamplona, Spain. These powerful, majestic creatures form an impenetrable wall and chase waves of people who are running purely for the thrill of the event. This is the kind of thrill that only a certain type of person can appreciate.

This same thrill is what the Rumble Rumble slot machine from Ainsworth attempts to deliver. This slot game may not put your life at risk like the famous festival in Spain does, but it will give you a shot at winning big, exciting prizes. This is also a nice balanced slot game as it falls somewhere between simple and complex. There are two different bonus features, but they shouldn’t be foreign to you if you’ve played other modern slot games.

  • Getting Started

    While Rumble Rumble is a pretty normal casino game, it doesn’t really bear too much resemblance to any other Ainsworth slots. This won’t be a problem as long as you’re familiar with the Ainsworth slot game interface and how slot games work in general. Here are some quick facts about the Rumble Rumble slot game:

    • This slot game has 5 reels and 3 rows for a grand total of 15 symbols
    • There are 100 different paylines which you can turn on and off in the settings menu
    • The minimum bet is €0.01 per line
    • The auto spin feature lets you play until you’ve won or lost a certain amount or played a certain number of spins

    Features & Overview

    All in all, Rumble Rumble is a good slot game. It’s great if you’re looking for something to switch it up from other Ainsworth slot games with King Strike or Quad Shot features. This is one of those free slot games where all you really have to worry about is spinning the reels, but there are still features available to keep you from doing that all day.

    The Rumble Rumble casino game isn’t the best when it comes to graphics. The actual graphics don’t look too bad, but the game is a bit crowded visually and the overload of bright colors makes it feel a bit cheap. However, the gameplay is good enough that this isn’t a major issue by any stretch.

    Bonus Rounds

    Rumble Rumble is a simple slot game but there are still 2 different bonus features that you can activate. Here is how they work.

    The free games feature is triggered when you land 3 or more scatter symbols anywhere on the board:

    • You get 8 free games
    • All reels expand to have 9 positions instead of the standard 3
    • The Fire Bull symbol can only appear on the top three spots of the 2nd and 4th reels
    • The Coin symbol can only appear on the top three positions of any reel
    • Landing another 2 scatters wins you an extra 5 free games
    • A different paytable and set of reels are used for these spins

    The other bonus feature in Rumble Rumble is the Fire Bull feature. This feature is triggered when the Fire Bull symbol appears with a blue border on the 2nd or 4th reel. When this happens, all symbols on that particular reel are changed to wilds. If the border of the symbol is red on reel 2, everything on the first three reels is changed to a wild symbol. If a red border appears on reel 4, reels 3, 4 and 5 are turned wild.

    The Final Verdict

    With the number of good slot games out there, it’s difficult to recommend Rumble Rumble over any others. However, this slot game has a couple of really neat bonus features, and despite its lackluster design is made by one of the better slot game manufacturers. Rumble Rumble is a solid choice for anybody who’s looking to switch it up without complicating things too much.
