Are you ready to rock your way to big wins? Spinberry’s latest creation, Heavy Metal Wilds, is the ultimate thrill for online casino game enthusiasts and music lovers alike. This online slot combines the electrifying energy of heavy metal music with an adrenaline rush you’ll only find playing on the best online casinos for real money. Whether you’re a fan of head-banging tunes or just looking for fun and interesting casino games online, Heavy Metal Wilds promises a high-voltage slot game adventure.

Game Overview

Heavy Metal Wilds is a unique online slot game that stands out with its rock and roll music theme. This game offers an immersive experience where shredding guitars and booming drums meet casinos, wilds, and free spins slots. With an impressive range of on-theme symbols, including guitars, microphones, skulls, and raised horns hand symbols, every spin resonates with the spirit of rock and roll.

The game rolls out on a sleek minimalist 5×4 grid and players can score wins through 20 paylines. The RTP (return to player) on Heavy Metal Wilds is a bit lower than the average online slot machine, sitting at 95.13%, and features medium-volatility variance. The highly volatile soundtrack more than makes up for it, though.

It also means this game is suitable for a wide range of players. Whether you enjoy a steady gameplay experience or you’re an adrenaline junkie looking for big wins, the game strikes a neat balance between frequent smaller wins and the chance of landing larger payouts.

How To Play

Getting started with Heavy Metal Wilds is as easy as hitting a power chord on a guitar. You’ll set your stake and hit “Spin” to get going. There is also an auto-spin feature that allows you to select between 10–500 spins that the game will automatically perform for you.

The betting range is really generous, offering increments of between $0.10–$250 per spin. So, if you’re just starting out on online slot games, you won’t have to break the bank, but if you’ve got the paper to make it rain, you can go wild.

Your goal is to align at least three identical symbols on a payline. Wins are determined by the paytable, where different symbol combinations offer different payouts. Some combinations will also trigger bonus features, and successful spins are rewarded accordingly.


Heavy Metal Wilds is a modern-looking online slot machine that uses shades of black and metallics to pay tribute to the live music atmosphere you’d find at a festival. The game’s graphics are designed to reflect elements of heavy metal music, even using edgy font choices to represent classic card symbols.

The soundtrack is a blend of electrifying guitar riffs and rolling drum beats that set the perfect backtrack for playing casino games online. Your grid sits on top of a smokey scene that looks like something from the front row of a stadium concert. This immersive audio-visual combination makes Heavy Metal Wilds quite a rock ‘n roll spectacle.


If you’re looking for an online slot machine that offers more than just the standard gameplay experience, then Heavy Metal Wilds might just be what you need. This game is packed with features that can elevate your gaming sessions. It comes with a re-spin feature that triggers when a full reel contains the same picture symbols.

Triggering this feature turns the whole reel into stacked wilds that lock in place for the re-spin to maximize your winning chances. If you land another full reel of picture symbols, you’ll lock in another stacked wilds reel, and your re-spins will continue for every reel full of picture symbols.

Heavy Metal Wilds also packs a free spins feature that activates when you land nine or more scatters across reels 2, 3, and 4. Nine scatters will get you eight free spins, 10 or 11 scatters will award 10 free spins, and 15 scatters will get you 12 free spins.

During Free Spins, win lines pay both left to right and right to left, as well as center-winning combinations. You are also still able to trigger the re-spin feature during this round, so wins can really start to pile up.

If you want to trigger eight, 10, or 15 Free Spins instantly, you can also use the Buy Feature and purchase them using your credits. There’s also the Feature Spin mechanic that allows you to trigger eight free spins during a single-mode, one-payline pre-game by matching three scatters.

Bonuses and Jackpots

Heavy Metal Wilds isn’t classified as a jackpot slot as it doesn’t feature a progressive jackpot. But it still offers the potential for substantial payouts of up to 800x your stake. If you think of that generous betting range, this really adds up. If you max your winnings on a max bet of $250, that’s a hefty $200,000 you could take to the bank.

There are a couple of ways to push your winnings in this game. The gamble feature allows you to gamble your winnings in a mini-game where you choose the color or suit of a card drawn from a deck. If you get the correct color, your gamble amount is doubled, and if you guess the correct suit, it’s quadrupled. You can gamble up to five times or until you’ve reached the max win. But remember, if you get it wrong, you’ll lose your winnings.

When your balance drops to less than the stake amount from the last spin, the Bet Chance feature is activated. In this mini-game, you spin a dial, and if your landing position is green, you win a free spin on the last stake amount. However, landing on red means you lose and the game will take your remaining credit.

Similar Games

If you enjoy music-themed slots, there are a number of other epic titles to try out. Other games you should explore are Rock ‘n Lock by renowned game developer Red Tiger or even a game like Jimi Hendrix from the NetEnt Rocks series and play with the legend himself.
