Ah, good old Nintendo-style arcade games from the 1990s. The graphics are dated, but everything retro has a cult following now. And the possibility to earn a certain amount by playing such a game makes things way more interesting. In 2017, Thunderkick took that concept and released Flame Busters. The slot quickly gained popularity thanks to its retro design paired with an innovative concept. Here you’ll learn everything about Flame Busters’ features, and how and where to play this slot.

How to Play

Playing online slots is never rocket science. They are quite intuitive, so players don’t have to study the rules of the game for hours. Thunderkick’s Flame Busters is no exception. To play the game, you need to follow the next simple steps:

  1. Find the game in the lobby of the online casino

  2. Click on it, and wait till the slot completes loading

  3. Check out the rules and playtable

  4. Select the size of your bet

  5. Hit the spin button and start playing

While Flame Busters may look like a retro arcade game, it is a typical slot with five reels and three rows. The slot has 243 fixed betways for you to land winning combinations on. The Flame Busters slot offers fourteen bet options. The minimum wager is just €0.10, while the maximum stake is €100. The bet size is reflected in the amounts earned from winning spins.

Flame Busters RTP and Volatility

8.8 

The Flame Busters slot has medium volatility and an RTP of 96.1%.

The theoretical return-to-player ratio in Flame Busters is 96.1%, which means that players have a good chance to get winning spins. On the other hand, it’s a medium variance slot, which means that players will face dead spins from time to time. The slot is perfectly balanced, as it is easy enough to land winning combinations, but hard enough to keep players interested.

Theme

8 

The Flame Busters slot is designed as a retro video game, thus the graphics deliberately look dated. As the title suggests, the slot is about firemen. The grid is presented in the form of a building, with two firefighters on the right side of the grid, and one on the left side. The fire erupts in the windows of the building during the spins. When firefighters extinguish the flame, a new symbol is revealed in the window.
The primitive, funky electronic soundtrack accompanies the game. Whenever you get a winning spin, you can hear an electronic bubbling noise as the winning amount is counted.

The Flame Busters slot is packed with interesting symbols. The card symbols are presented as coins, and they are low-value characters. Nonetheless, they play an important role in the special feature, which we are going to discuss a bit later. Other symbols include a goat, pirate, wizard, robot, and firefighter with a cat. A firefighter with a cat is the highest-paying regular symbol. Landing five of them across the payline can bring you ten times your initial bet. And surely there are special symbols:

Fire Symbol — a mystery symbol, the flame erupts replacing the symbol, and when it is extinguished, the new symbol will be revealed.

“W” Symbol — a wild symbol, substitutes all characters, except the scatter.

Alarm Bell — a scatter symbol, landing three, four, or five of them will award a player with ten, fifteen, or twenty free spins.

Mind that, the mystery symbol can change all the symbols, except the wild and the scatter.

Mobile Compatibility

Mobile Compatibility
It’s hard to find a slot that’s not mobile-friendly nowadays. The Flame Busters slot is compatible with both iOS and Android mobile devices. The main difference is that on the desktop building you see just the building and the symbols. The mobile version reveals all that occurs on the screen of an arcade machine. So, if you want to be immersed in the atmosphere of playing an arcade game, opt for the mobile version.

Bonus Rounds & Free Spins

8 

The Flame Busters slot has two special features. The first one is the Fire Drill feature, which occurs during the base game. The second one is the Bonus Games, which can be triggered by the scatter symbols.

Fire Drill

The Fire Drill feature is triggered randomly during the base game. During this feature, players have chances to earn a bit more. Coin symbols turn into Fire symbols for the next spin. The good news is, coin symbols can not change back to themselves after the ignition. Thus, they will turn into symbols of a higher value.

Bonus Game

Bonus Game is presented in the form of free spins. Landing three to five Alarm Bells on the reels will trigger ten to twenty free spins. The feature can be re-triggered by collecting scatter symbols during the feature. With each Bonus Game feature, you move one floor up. The coin ignition works during the feature as well. If you get five floors up, there’s a possibility that all the coin symbols will ignite and turn to characters of a higher value.

Flame Busters Demo play

The best option to get acquainted with any slot is to play it in the demo mode first. The demo version of Flame Busters allows you to get to know the game.

Max Win

7.9 

The promised maximum win in the Flame Busters slot is 5,280x your bet.

The promise maximum win in Flame Busters is 5,280 times your initial bet. The players can hit the jackpot during the Bonus Game feature. If you get to the fifth floor, where all the coin symbols turn into higher-paying characters, you have the possibility to get the promise maximum payout. Also, pay attention to the bet size. With the minimum bet of €0.10, your total win will be just €528. But you can win up to €528,000 if you opt for the maximum bet of €100.
