Six Feet Under online slot game

Six Feet Under is an online slot from Nolimit City, released in October 2026. The game stars a serial killer who takes "friends forever" very literally, burying his loved ones six feet underground. Regular combinations barely pay anything here, and what matters are the buried gems, which pay multipliers of your bet. To dig them up, you'll need bomb symbols.

Six Feet Under - Right for You?

• Play this if: You enjoy digging-up-treasure mechanics, very much in the style of the Fire in the Hole series from the same provider.
• Better skip it if: Going several spins without a win drives you crazy.
• Minimum bankroll: 100 EUR.

Six Feet Under: Slot Overview

Theme and First Impressions

The premise, a murderer who buries his friends so the friendship can last forever, would sound grim coming from another studio. But it works here, thanks to the same black humor Nolimit already showed us in Serial and Disturbed. Both the visuals and the sound have that trademark Nolimit City feel. It's creepy, but never takes itself too seriously, and we're big fans of it.

How Six Feet Under Plays: Base Game

In the base game you get a 6x6 grid. On every spin, the bottom rows are randomly covered with dirt, and hidden under that dirt are gems that pay a multiplier of your bet. To dig them up, you need bomb symbols landing on the upper rows.

The slot also has a cascade feature, so when you land a win, the winning symbols explode and new ones drop in. With each new cascade, the gems go up in value.

There are no classic paylines or clusters. Instead, you get up to 46.656 ways to win, formed by matching symbols on adjacent reels starting from the left.

Only the gems and Bonus symbols are important in this game. The basic combinations pay very little and often just get in the way, as this paytable for a 1 EUR bet shows.

Six Feet Under - Bonus Features and Free Spins

As usual with Nolimit City slots, Six Feet Under comes packed with special features.

Bombs

Bombs clear pay symbols and dirt in their own patterns:

• Small Box Bomb: explodes in a 3x3 pattern.
• Teddy Bear Bomb: explodes in a cross shape, removing up to 2 symbols in each of the four directions.
• Big Box Bomb: explodes in a 5x5 pattern.
• Glass Can Bomb: smashes 3 full rows, its own plus the ones directly above and below.
• Gasoline Bomb: same idea, but with 3 columns, its own plus the ones to the left and right.
• Cake Bomb: combines the cross and the diagonals, clearing its entire row, its column, and both diagonals running through its position.

Gems

Each gem carries a value, and when a bomb clears the dirt covering it, that value is multiplied by your base bet and paid out. The possible base values are 1x, 2x, 3x, 5x, 10x, 20x, 50x, 100x, 200x, and 1.000x.

On top of that, at the start of every cascade, each gem goes up in value by its own base amount. For example, if a 50x gem survives three cascades, it's worth 150x.

Gem Upgraders

The slot also has two symbols that boost gems:

• Shovel: when it lands, it removes itself and randomly adds gems to the empty dirt positions on its reel. Any gems already on that reel get upgraded to higher values too.
• Toolbox: works just like the Shovel, but affects all reels at once.

The Descent

The Descent triggers when you unearth at least 3 Bonus symbols. The round starts with an empty grid, so landing gems is much easier. That said, each new spin adds more dirt along with the symbols.

In theory, the feature is infinite, since it only ends when the entire board is buried. In our tests, though, we usually got between 8 and 12 spins before that happened.

Also, for every extra Bonus symbol beyond 3 that triggers The Descent, one low-value gem is removed from the round.

Side Hustle

These are side bets that make each spin more expensive and let you bet on a specific outcome:

• Explode Small Box Bomb / Teddy Bear Bomb / Big Box Bomb / Glass Can Bomb / Gasoline Bomb / Cake Bomb: pays if that specific bomb type explodes on your spin.
• 12 Freespins: pays if The Descent reaches 12 cascades or more.
• No Dirt: pays if the spin ends with no dirt left on screen.
• Dead Spin: pays if the base game spin ends with no win at all. In other words, you're betting on losing.

We tested some of these and didn't love them. They're too volatile and push the cost per spin up fast. On top of that, we confirmed the game's RTP drops when they're active.

Bonus Buy

For the impatient, there is the bonus buy menu:

Nolimit Booster (base game modifiers):

All of these options sit around 96% RTP, so there's no "cheat" option here. Still, we're of the opinion that buying bonuses just speeds up how fast your balance moves, in one direction or the other.

What to Expect When Playing Six Feet Under Slot

We played 200 spins on Six Feet Under at 1 EUR each using the demo, on both mobile and desktop.

The best part of the session was The Descent, which triggered four times:

• The first, surprisingly, came around spin 4 with four Bonus symbols and paid us 92,15x.
• The second on spin 166, also with four Bonus symbols, for a 59,80x win.
• The third on spin 172, with three Bonus symbols and a modest 4,60x.
• The fourth on spin 191, also with three Bonus symbols, paying 40,10x.

As for the base game, we found it too slow. We went through stretches of 5 to 20 spins without a single win, not even a basic combination. Our biggest base game win outside the bonus was a modest 10x.

In the end, we finished at 10.085,80 EUR, having started with a 10.000 EUR demo balance.

Win Potential and Volatility

The ceiling here is 30.000x your bet. Decent, but not the highest Nolimit City offers. Fire in the Hole 3, for example, can pay up to 70.000x.

The theoretical RTP is 96,05%, just above the 96% we use as a benchmark. Bonus buys can nudge that figure up or down a few decimals, but it never drops below 96%. With Side Hustle active, though, it can fall to less than that.

This is an extreme volatility slot, so you'll need a healthy bankroll and plenty of time. During our session, we went through long stretches where the balance bled out spin by spin, broken up by sharp recoveries when bombs uncovered big gems or The Descent kicked in.

Mobile Performance

The game ran smoothly on both Android and iPhone. Best of all, it adapts well to smaller screens and the touch controls respond nicely, something important in a slot where you're constantly choosing between so many options.

Best Alternative Slots to Six Feet Under

Since Six Feet Under builds on Nolimit City's digging and controlled-chaos mechanics, it makes sense to compare it with Fire in the Hole 3 and xWays Hoarder 2, two of the studio's flagship titles.

If you're chasing the biggest possible win and don't mind maximum risk, Fire in the Hole 3 is the obvious pick. If you prefer the xWays and xSplit mechanics so many of us enjoy, xWays Hoarder 2 gives you more mileage per session in exchange for a slightly lower ceiling. Six Feet Under doesn't have the biggest top prize or the longest feature list, but its mix of bombs and growing gems is unique in the catalog.

Final Verdict: Is Six Feet Under Worth Playing?

What we liked most about Six Feet Under is how the bombs, gems, and cascades play off each other. Plenty of times, when everything looked lost, one well-placed bomb cleared most of the board and saved the spin.

Its biggest weakness is how punishing the base game is. Regular symbols pay very little and, while they help build cascades, they mostly just get in the way.

This slot is best suited to seasoned high-volatility players with a bankroll that can handle thousands of spins. If you're planning to play on a tight budget hoping for a lucky hit, chances are the game will eat your balance first.
