Play Rumble Rumble for Free

As far as 5-reel video slots go, Rumble Rumble isn't going to throw up too many surprises to seasoned spinners. That is because the game is actually fairly generic in its design and theme, showing a familiar looking game screen that is emblazoned in flames.

On the reels, there are myriad different beasts and animals displayed as game symbols, giving the game an extra element of intrigue. There are mysterious stags, for example, as well as magnificent steeds, awesome soaring eagles, lone wolves and fiery bull icon that plays an integral role in helping spinners to create bigger winning jackpots.

The graphics of the game are suitably detailed with plenty of clarity and colour, meaning that players will be able to enjoy plenty of a eye-catching spins. Although, having said that, the game does appear to be slightly dated when it comes to the quality of the visual effects. This means that the game takes on the appearance of an old-school land based video slot rather than a cutting edge innovative online slot, which is perfectly fine for punters who are looking for a bonus filled game that has some retro charm about it.

Speaking of bonuses, this game offers up a number of symbols which are bestowed with special gameplay characteristics. There are a couple of special golden coin icons, for example, both of which are designed to feature some more bulls. One of these coins in a scatter symbol that pays wins that multiply the value of the total bet by 1x, 10x and 100x whenever three, four or five appear in any position on the reels. The other golden coin is a “wild” symbol that will help players to complete winning formations for any other symbols that pay their wins as a line bet multiplier.

The game also features a very special fire bull symbol, which gives players the chance to boost their winning totals during the base game of Rumble Rumble by adding expanding wilds on to the reels. This works in a fairly simple way, because all players have to do for the fire bull icon to work its magic is wait for it to land in any of the flashing blue or red squares that appear on the second and fourth reels.

If the fire bull fills a blue square, then it will transform that entire reel into an expanded wild symbol. If the fire bull lands in the red squares, then it will cause every surrounding reel position to take on wild properties. As you can probably imagine, this gives players the potential to make some very big prize totals with multiple wins.

Players can hope to increase their wins even more with the Rumble Rumble round of free spins. This bonus feature is triggered by players who happen to find three or more scatters, opening up a new game screen which shows a fresh set of 5 reels, this time with 9 symbol positions instead of 3. This set of free slot games still offers the chance for fire bull symbols to cause expanded wilds and there is every opportunity for spinners to make the most of these wager-less spins since two extra scatters on the reels will offer 5 more free games.

Now that you know how to play the game, it's about time we told you about the wins on offer in this slot machine. In truth, the paytable isn't that impressive with line wins that offer no more than 1,000x the value of the line bet. What's more, the available wagers per line are somewhat small with options that range from 0.01 credits to 0.75 credits. Nonetheless, with 100 paylines and frequent expanded wilds, players can easily rack up some sizeable wins.

Rumble Rumble may not offer anything new or interesting when it comes to the visual aspect, but it sure does cause a rumble or two with its unique gameplay action. As such, fans of video slots should be more than satisfied with this slot machine's bonus win potential, as long as they don't mind spinning some reels that aren't quite designed to the same standard as other contemporary games.
