Rumble Rumble Online Slot: Fire Bull Turns into Glorious Wild Reels to Bring Amazing Wins!
Rumble Rumble is an amazing slot machine game by Ainsworth, now being deployed to online casinos via the NextGen Gaming platform. The outcomes can be a mad rush of Wilds once the Fire Bull icon lands on special reel positions. Entire reels turn into Wild Symbols, greatly increasing the possibilities of completing matched groupings in any of the 100-payline configuration.
The win possibilities are even greater once the game advances to the Free-Spins Round. The bonus spins are played on a colossal 9 x 5 grid that further optimizes the Fire Bull-Wild Reel transformation feature.

Rumble Rumble Wild Symbol
A tile labeled plainly as WILD appears in any reel. If a WILD lands in a pay pattern along with identical regular-paying icons, it can complete or extend groupings of 2, 3, or 4 identical symbols into winning combinations. Payouts awarded will be based on the equivalent rewards of the winning symbol, since the WILD is only posing as a substitute icon.
Yet when 3 or more WILDs form a winning combination in any payline, Rumble Rumble players can expect greater returns. Winning WILD combos of 3, 4, or 5 symbols award base-game pays equivalent to x3, x10, or x50 of the coin bet per line. The reward for a 5-symbol WILD Win is higher in the free games, as the symbol awards x100 of the coin bet.
When it comes to Wild-completed wins and winning WILD combinations, the emergence of the special Fire Bull icon increases the odds of reaping multiple and/or top-paying rewards from a single spin.
Rumble Rumble Online Slot: Fire Bull Wild Transformation Feature
The Fire Bull is a special icon configured to appear only in Reels 2 and 4. Take notice of the Blue and Red Frames randomly appearing in those reels. A Fire Bull landing on either frame triggers the transformation of one or more reels into full reel WILD/s. The transformation though, depends on the color of the Frame and the Reel in which the Fire Bull emerged.
• A Fire Bull that takes position inside a Blue Frame in Reel 2 or Reel 4, turns that particular reel into a Wild Reel.
• The Red Frame is more potent, as a Fire Bull landing on a Reel 2 Red Frame transforms Reels 1, 2 and 3 into Wild Reels.
• On the other hand, a Fire Bull that finds its way to a Reel 4 Red Frame, transforms Reels 3, 4, and 5 into Wild Reels.
• The best outcome is when two Fire Bull icons simultaneously appear; one in the Reel 2 Red Frame and the other in the Reel 4 Red Frame. Such an occurrence turns all Rumble Rumble Reels into Wild Reels.
In the event that a Coin Scatter appearance coincides with the occurrence of the Fire Bull Wild Transformation, the Scatter Symbol merely becomes a Coin Wild. As such, it poses as both substitute and bonus game trigger symbols.
Rumble Rumble Online Slot: Coin Scatter Symbol
The Gold Coin icon inscribed with the image of the Fire Bull is a Scatter Symbol. As a symbol configured to appear in any reel or row, it awards Scatter Pays. In both Base and Bonus Games, three, four, or five Coin Scatters correspondingly pay a cash prize equivalent to x1, x10, or x100 the Total Bet that triggered the reward.
Moreover, at least 3 Coin Scatters trigger the Rumble Rumble Free-Spins Bonus Round.
Rumble Rumble Free Games
Eight (8) bet-free spins will be awarded as initial number of bonus games. The free round will be played in a set of 5 Colossal Reels; each reel displaying 9 layers of symbols. During the bonus round, at least two (2) Coin Scatters in view, including the Coin Wild, trigger five (5) extra free spins. However, Coin Scatter appearances across the reels are confined to the first three positions of the bonus game reels.
The Fire Bull Wild Transformation Feature remains active, but with a slight modification. Like the Coin Scatter, the Fire Bull icon can only appear in the first, second and third tiles of Reels 2 and 4.
