Race towards victory and big wins in Bullshark Games’ latest release, Astro Rumble!

Zoom past opponents and leave behind a trail of galactic dust as you race towards the finish line of Astro Rumble – a 5×4 Video Slot with fixed pay lines and up to 10,000x your bet in prizes.

As you put the ‘pedal to the metal’, look out for Pot of Wild, Multiplier, and Nitro symbols, each offering an exciting boost that aids you in the final lap. Alternatively, in Free Spins, special collect features will grow your rewards with every spin.

The illustrious Space theme in Astro Rumble is something we’re used to seeing in the iGaming industry. We’ve defied gravity on many occasions in games like Space Miners, Space Attacks Dream Drop, and even in our very own Buzz Thrill release, but it’s our first time competing in a galactic race for wins.

Utilising a fixed RTP of 96.39% and a high (4/5) volatility rating, Astro Rumble can produce up to 10,000x in max win potential. With this figure in mind, let’s get our heads in the game and zoom our way towards big wins!

Base Game & Features

Astro Rumble is a highly volatile 5×4 Video Slot with 14 fixed pay lines. Wins are outlined when 3, 4, or 5 identical symbols land from left to right, on adjacent reels, starting from the leftmost reel.

The game consists of 11 paytable symbols, including Scatters & Wilds, with the potential to award payouts between 0.1x and 20x your bet. Wild symbols present on all reels and substitute for all paytable symbols, while Scatters are responsible for triggering Free Spins.

Pot Features

During gameplay, up to 3 Pot Features can trigger above reels 2-4 of the main reel set. Once active, the following Modifier Outcomes trigger:

  • Nitro: Allows up to 10 Nitro symbols to appear within the triggering spin. Alternatively, during Free Spins, all Nitro symbols that appear will be added to their respective pot after each spin.
  • Wild: Awards up to 10 Wilds onto the reels during a single spin. Wild symbols that appear on top of another will add +1 to the Multiplier Pot. Alternatively, in Free Spins, all Wilds are collected, and the previous wild remains in the pot for the next spin.
  • Multiplier: Guarantees up to 10 (x2-x100) Multipliers will be added to random paytable symbols for each spin. Winning symbols with Multipliers will apply their values to the total win before the next spin. Alternatively, in Free Spins, each Multiplier adds +1 to the pot throughout spins.

Cosmic Boost

Triggering the Cosmic Boost feature is done so within the base game, at random. Once available, between 1 & 3 Pot Features activate within the triggering spin. Please note that Scatter symbols are not available during this feature.

Featurespins & Bonus Buy

Players outside the UK jurisdiction can access 4 Bonus Buy/Featurespins options from the following:

  • Bonushunt Featurespins: Guarantees that each spin is 5 times more likely to trigger a Free Spins feature for 3x your bet per spin.
  • Cosmic Featurespins: Guarantees a spin with the Cosmic Boost feature active for 50x your bet per spin.
  • Rocket Race: Triggers the mode with 8-10 Free Spins and progressive pots for 100x your bet.
  • Galactic Rush: Triggers the mode with 12 Free Spins and all 3 Feature Pots available for 300x your bet.

All 4 of the Bonus Buy/Featurespins options include a theoretical RTP between 96.32% and 96.28%.

Astro Rumble has a fixed max win potential of 10,000x your bet. If a game round should exceed this figure, the current mode will end, and the player returns to the base game with the 10,000x max win in tow.

Astro Rumble Free Spins

Triggering the Rocket Race mode requires 3-4 Scatter symbols to land in the base game, awarding 8-10 Free Spins, respectively.

At the start of this round, a single Pot Feature with a fixed value between 2 & 5 is awarded. Otherwise, the game follows the same mechanics found within the base game. Finally, landing 2-5 Scatters awards an additional 2-5 Free Spins, respectively.

Galactic Rush

In addition to the Rocket Race mode, the Galactic Rush feature can be triggered by landing 5 Scatter symbols in the base game, awarding 12 Free Spins.

During this time, all 3 Feature Pots start the round with a random value. Otherwise, the game retains the same mannerisms as the Rocket Race mode.

Our Honest Verdict

Astro Rumble from Bullshark Games takes us out of our usual environment (of breathable air and gravity) and places us in a competitive, galactic setting to participate in a race for big wins of up to 10,000x your bet.

Bullshark Games’ interpretation of space leaves little to be desired via the game’s design and aesthetics. The base game backdrop reveals an orange dirt track, a stadium, and a couple of planets floating nearby. However, in Free Spins, the backdrop is gleaming with bright stars and the flash of neon lights.

With only the Feature Pots available in the base game, there are many pin-dropping moments, particularly without any interaction from the Cosmic Boost feature. These pots are responsible for applying Wilds, Nitro, and Multiplier symbols onto the reels.

The Nitro modifier is an enhancement of the highest-paying symbol, appearing on the reels in higher consistencies once active. This is particularly rewarding on its own; however, when paired with the Multiplier and Wild pots, they can generate astronomical payouts.

Statistically, Astro Rumble is a standard addition to Bullshark Games’ growing portfolio, offering a fixed RTP of 96.39% and a high volatility score. This maths model, accompanied by the 10,000x max win potential, makes Astro Rumble a great option for Bullshark followers.

All in all, Astro Rumble is an impressive release from Bullshark Games, operating exciting mechanics, features, and a quirky space-racing theme.
