Let our expert online gambling review guide you through the maze that the free Rumble Rumble video slot seems to be.
One Crazy Horse
The first thing you notice is the size of the screen - don't turn off the computer, there's nothing wrong and you haven't struck upon the mobile optimised format. The slim game is because the Free Spins Bonus round features expanding reels which wouldn't fit on the screen in standard landscape layout. The downside to this is that the paytable etc can be difficult to view.
The next thing that strikes you is the bright, clashing colours and flashing squares. This is not an online slot that is aiming for subtlety or finesse. You can appreciate that, in a room full of land-based AWPs screaming for attention, it's difficult to make a game stand out of the crowd. Someone needs to tell Ainsworth that competition amongst online slots is played by a different set of rules now.

Always Read the Paytable
To understand the purpose of those flashing blue and orange neon squares on reels two and four we need to review the paytable.
High-paying symbols are stag, stallion, eagle, wolf and rock mountain, which payout between 800 and 2,500 coins for 5 OAK on a max bet.
Low-paying symbols are the house playing cards 9 through A that gamers who are fans of software by Ainsworth will be more than familiar with.
Then there are the interesting symbols, which really get this online slot stampeding. There are the Wild Symbols, the word WILD, which offer 5,000 coins for 5OAK on a max bet and substitute all except Wild Coin and Fire Bull. There are the Scatter Symbols, Gold Coin and Wild Gold Coin, which both offer the fabulous 1,000,000 coins for landing 5OAK on a max bet.

Fire Bull On Two Reels Goes Stacked
Finally, there's the Fire Bull symbol who lands on Reels 2 and 4 only. When he lands in a blue flashing square a flamboyant voiceover yells, 'Sweet zone!' and the reel turns into a Stacked Wild. When the Fire Bull lands in the central red flashing square, the voiceover shouts, 'Super sweet' and three full reels are converted into Stacked Wilds.
The pace on the free Rumble Rumble video slot is fast, furious and in your face. The variance is fairly high and RTP is 94%, both of which we'd expect from software by Ainsworth. Landing Fire Bulls in the flashing squares can be fairly frequent (so, you've gotta love that voice or use the mute button!), but achieving win lines of the highest paying symbols is more challenging.

Free Spins and Expanding Reels
Three Coins or Wild Coin Scatter Symbols will trigger the 8 Free Spins bonus round. The reels will extend from 5x3 to 5x9, stretching the entire length of your screen (you might even have to adjust screen size to accommodate the bet settings at the bottom).
There are still only 100 paylines in play, but, if, during Free Spins, your Fire Bull lands on a blue or red flashing square the number of Wild Symbols you get increases enormously, which increases winning potential, too.
