Demon Beats

Demon Beats Review

NetEnt released Demon Beats in October 2026. You're following a rock band whose tour has taken them to a temple full of demons. The drummer may be possessed, and the gig quickly turns into a fight to get out.

The grid has five reels and four rows. A win needs matching symbols across three or more reels, starting with the first one. Their position on each reel doesn't matter. The winning symbols are then cleared away and replaced through an Avalanche.

Things can change quite a bit from there. Colossal Symbols and expanding Wilds can turn up along the way. The regular multiplier tops out at 32x. Multiplier Upgrade is a different story, with 1x, 4x, 16x, 64x, 256x and finally 1,024x.

Demon Beats - Reels Screen

I found the Battle Feature one of the stranger parts of the game. A Battle Symbol left behind after a losing spin can bring Wilds or Colossal Symbols onto the reels until the symbol is covered. It can happen during the base game as well as Free Spins and Super Free Spins, so it isn't something you only see after reaching the bonus.

Three Bonus Symbols are enough for eight Free Spins, with as many as 14 available from six. A Super Bonus Symbol among them changes the round to Super Free Spins. The big difference there is the multiplier: it can still reach 1,024x, but unlike regular Free Spins, it doesn't reset.

Demon Beats has a 96.08% RTP and a maximum win of 10,000x the bet. NetEnt also includes its Elevate menu, where you can increase the chance of reaching the bonuses or pay to start particular features directly. Super Free Spins is the most expensive option at 300x the bet.

Demon Beats Features

There's a lot packed into Demon Beats, but most of it comes back to what happens after the reels stop. Symbols can disappear, bigger ones can break apart and the multiplier can move up before the spin is finally over. The two Free Spins modes take the same idea much further.

Avalanche

A win clears the symbols that made it and another set drops down. If that produces something else, the spin carries on.

I've found this is also the easiest way to follow the multiplier. Each successful step pushes it higher, so a longer Avalanche is worth watching beyond the individual wins it produces.

Wilds

Wilds replace regular symbols in winning combinations, but some can grow and cover more space on the reels.

One detail I wouldn't overlook is what happens when a sequence runs out of wins. A normal Wild can stay where it is. A Colossal Wild doesn't; it disappears.

Colossal Symbols

These are the oversized symbols you'll sometimes see taking up several positions. When a Colossal Symbol wins, both the big symbol and regular copies of the same symbol explode.

They can also crush symbols underneath them. This happens when there isn't a level surface for the Colossal Symbol to fall onto after other symbols have disappeared.

A losing spin doesn't always mean they're finished either. Colossal Symbols can explode together with their matching symbols even when no win has formed.

Multipliers

You'll see the multiplier below the reels. It begins at 1x and the next stops are 2x, 4x, 8x, 16x and 32x.

Wins move it forward, and an exploding Colossal Symbol can do the same. Getting it to 32x isn't permanent, though. A dead spin with no Colossal or Battle Symbol remaining can send it straight back to 1x.

Multiplier Upgrade

This is where that 32x ceiling can disappear. Multiplier Upgrade may be added randomly after the first base-game spin and gives you a different set of values: 1x, 4x, 16x, 64x, 256x, and 1,024x.

It's a huge jump at the upper end. The last step is 1,024x rather than 32x, using the same multiplier ladder found in the bonus rounds.

Battle Feature

A Battle Symbol can become important when a spin finishes without paying. If there are no Colossal Symbols around, it can start the Battle Feature.

This brings up to three Wilds or two Colossal Symbols onto the grid. The aim is to cover the Battle Symbol completely, either when those symbols land or as a Wild expands over it. Once it's covered, the battle ends.

Battles aren't restricted to the base game. I like that part, because the same mechanic can interrupt Free Spins and Super Free Spins too.

Free Spins

You need at least three Bonus Symbols. Three start you with 8 spins, four give 10, five give 12 and six give 14.

The multiplier is much more interesting here. Its six positions are 1x, 4x, 16x, 64x, 256x and 1,024x. You can still see the Colossal Symbols, Wilds and battles during the round.

More Bonus Symbols can extend it. Three add 3 spins, four add 4, and the pattern continues up to another 6 spins from six symbols.

Super Free Spins

Look for the Super Bonus Symbol when the bonus triggers. If at least one is among the triggering symbols, you go into Super Free Spins.

The multiplier still goes as high as 1,024x here. What changes is the reset. There isn't one. Once you've moved the multiplier higher, a losing spin doesn't knock it back to 1x.

Regular Free Spins can also be upgraded to this version. An upgrade with three Bonus Symbols gives 8 extra spins, increasing to 10, 12 or 14 with four, five or six.

Elevate

You don't necessarily have to wait for all of this to happen naturally. Elevate has six paid options, ranging from better bonus odds to starting Super Free Spins immediately.

The RTP changes slightly when you use Elevate. Multiplier Upgrade runs at 96.01%, while the other five options are 96.00%, compared with 96.08% for the regular game.

Theme & Graphics

Demon Beats looks more like a heavy metal show gone wrong than a typical demon slot. Their next gig happens to be in a demon-infested temple, which gives the whole game its setting. Guitars, speakers and other concert details mix with fire, skulls and the creatures hanging around the stage.

The characters are a big part of the design. They show up as larger symbols too, so the screen can change quite a bit when a Colossal Symbol drops in. I also like what happens during the Battle Feature. Wilds and Colossal Symbols crashing onto the reels fit the idea of the band actually fighting its way through the place.

The soundtrack does plenty of the work here. Heavy guitar riffs run through the game, with harder hits and effects when symbols explode or another Avalanche starts. It gets noticeably louder once more is happening on the reels.

There's a lot to look at, especially during longer sequences, but I don't think it becomes difficult to follow. The multiplier stays below the reels and the brighter feature symbols stand out well enough from the regular ones.

Demon Beats Free Play

Demon Beats free play gives you virtual credits to use on the same reels and features as the regular game. It's worth spending some time here, as there's quite a bit to pick up between the Avalanches, Colossal Symbols and the multiplier below the reels.

I'd also use the Demon Beats demo to get familiar with the two bonus rounds. Free Spins can take the multiplier as high as 1,024x, while Super Free Spins stop it from resetting between spins. The Battle Feature can show up in either round as well as the base game.

You can change the bet and play without spending real money. Any balance or wins in demo mode are virtual and can't be withdrawn. You can also play the Demon Beats demo version here, on this page.

Pros And Cons Of Demon Beats Slot

Demon Beats has more going on than the usual Avalanche slot, particularly once the multiplier starts moving. Super Free Spins are the standout for me, although getting there naturally isn't especially frequent.

Our Verdict

Demon Beats has a lot going on, but the Avalanches are what held my attention most. A spin can change several times before it's over, and the multiplier gives you a reason to care about what drops next. Getting from 1x to 32x in the base game already makes a longer sequence interesting. Once the 1,024x scale is active, the difference is much bigger.

I also enjoyed the Colossal Symbols more than I expected. They aren't just oversized symbols taking up reel space. Watching one crush its way down or explode with the matching symbols around it works particularly well with the Avalanche setup. The Battle Feature is another nice fit, especially since it isn't saved exclusively for the bonus rounds.

Free Spins are good, but Super Free Spins would be my main target. Keeping the multiplier instead of watching it fall back to 1x changes the round considerably. The downside is that Free Spins aren't particularly common at 1 in 254, and buying Super Free Spins through Elevate costs a hefty 300x the bet.

I'm less convinced by how many paid options NetEnt has put behind Elevate. It's useful to have a choice between boosting the bonus chance, starting a Battle or going straight into one of the Free Spins rounds, but six options feels like a lot. The slightly lower RTP when using them is worth remembering too.

For me, Demon Beats works best when several of its mechanics collide. A Colossal Symbol on its own isn't the attraction, and neither is another Avalanche slot with a rising multiplier. It's when a sequence keeps going, the multiplier has already climbed and a Wild or Battle changes the reels again that the game starts to stand out. Add the strange heavy-metal tour through a demon-filled temple, and this is one of the more unusual NetEnt slots I've played recently.
