Rumble Rumble Slot Review

Ainsworth are the developers behind the Rumble Rumble slot machine, which focuses on rather majestic looking images of animals, particularly rampaging bulls.

Is this the most original theme in the online slot world? Ainsworth is such a small developer of slots that nobody is going to chastise them for that. The slot machine is very basic and is intended to be played on mobile casino devices.

Rumble Rumble offers up everything you would expect from a small-scale slot, such as flashy graphics, a primitive payline structure, and a no-frills attitude to gameplay.

Developers

Ainsworth’s catalogue is not vast, and most of their games seem to offer the same kind of structure and setup. Sometimes this repetitiveness can be frustrating, and yet at other times it is nice to play something you can easily work your way round in just a few moments of practice.

Rumble Rumble is a little bit of both. At times, it reminds us of WMS Gaming’s Raging Rhino slot, and at other times it looks like something we’d expect Novomatic to produce.

How to play

Rumble Rumble features a fiery backdrop, with rage-ridden bulls and a bold, block title occupying much of the screen. The reel set is small and contains plenty of customary high playing card imagery upon it, as well as the more thematic icons.

The wagering menu is basic, but does fit the style of the slot, and is attuned for mobile users. Players can adjust the slot’s 100 lines via the cog symbol, and that same symbol will also see them able to wager anything from $0.01 up to $100 per spin.

Features

Wild symbols: Don’t expect too many goodies to do the rounds in this slot. As a matter of fact, you will only find a handful of them. There is a wild, in the shape of a bold block of text.

Wilds are the best-paying symbols in the game and can substitute for all other symbols in this mobile slot, save for scatters. When a flaming bull (fire bull) icon appears on the second and/or fourth reels with a flashy square emblem around it, all the symbols on that reel or those reels will turn into stacked wilds.

Scatter icons: Scatters appear as golden coins. These symbols can offer scattered wins wherever they land on the reels of the game.

Players can land 1x, 10x, or 100x their total stake with these symbols. Notably, they can also appear with the word “wild” written on them. When this occurs, players will find that the conjoined symbols will become scatter wilds.

Free spins bonus: Landing 3 or more scatters on the reels will trigger Rumble Rumble’s free spins bonus. Initially, players will start out with just 8 free games in total. However, a different set of reels will be used to play this bonus.

The bonus reels are 9 symbols deep, and free spins can be retriggered by landing a mere 2 scatters on the reels whilst the bonus round is in session.

Maximum pay-outs

All in all, it is possible for players to win as much as 100x their total bet with the Rumble Rumble slot. It is not the most entertaining video slot ever developed, and it began its life as a land-based slot (which offered considerably better winnings).

Just why Ainsworth decided to cut down the value of the prizes for their mobile/online version is unknown. As we’ve said, to win the top prize you need to land 5 scatters in any positions on the reels.

Summary

Rumble Rumble is a primitive slot machine. Normally, when a casino software developer brings one of their land-based hits to the online and mobile casino world, they jazz it up a bit.

Ainsworth seems to have done the exact opposite, they have left it largely as it was, but reduced its appeal in other areas, such as by lowering the amount you can win. If you happen to be playing in a mobile casino which offers Ainsworth games, then this slot might be worth a quick look.

We wouldn’t actively go looking for this game, though, as it doesn’t offer too much in return for your hard-earned cash.
