Six Feet Under

By Zena Grantham | Updated 22 October 2026

Six Feet Under is a horror-themed video slot from Nolimit City, released on 20 October 2026. Making friends can be difficult, especially when your idea of a lasting relationship involves a shovel and a freshly dug grave. Nolimit’s latest creation introduces a deeply disturbed character who takes the phrase ‘best friends forever’ a little too literally.

With a sinister graveyard theme, twisted humour, and a maximum win of 30,000x the bet, Six Feet Under makes it clear that some friendships are better left buried.

Technical

Six Feet Under features a six-reel, six-row grid, with up to 46,656 ways to win. Winning combinations require at least three matching symbols on consecutive reels, starting from the leftmost reel. The slot features a cascading system, where winning symbols disappear, and new ones fall into the empty spaces, potentially creating further wins from a single spin.

Betting ranges from £0.20 to £100 per spin depending on your jurisdiction. In the UK, gambling regulations cap players’ spin stakes at £2 per spin for 18- to 24-year-olds and £5 for players aged 25 and over.

The default Return to Player (RTP) is 96.05%, though alternative versions at 94.02% and 92.07% are also available. With a hit frequency of 21.90%, winning combinations occur approximately once every 4.6 spins on average. Nolimit City has assigned Six Feet Under an extreme volatility rating, so payouts will be infrequent and vary considerably in value.

The maximum win is 30,000x the bet. Six Feet Under is fully compatible with desktop and mobile devices, including smartphones and tablets, with no download required.

Design

Nolimit City is no stranger to disturbing themes, but Six Feet Under takes a more restrained approach to its sinister storyline. The action unfolds beneath the surface, on a six-by-six grid that resembles an excavation pit surrounded by crumbling earth, exposed rock, and wooden supports.

Torn playing-card symbols appear among an assortment of unusual objects, including a helmet, boots, explosives and coloured gemstones. The latter provide a welcome splash of colour against the dark surroundings, while the bold red logo adds a suitably ominous touch.

Despite the macabre premise, Six Feet Under lacks the visual impact associated with Nolimit City’s more provocative creations. The underground setting serves its purpose, but without a prominent central character or unsettling imagery, it looks rather bland. Given Nolimit’s reputation for pushing boundaries, this grave could have been dug a little deeper.

Symbols

The lower-paying symbols feature the familiar playing-card ranks 10, J, Q, K and A, printed on torn scraps of paper. Wins require at least three matching symbols on consecutive reels starting from the left, and six-of-a-kind combinations award between 0.5x and 0.9x the stake.

Higher-paying symbols include personal belongings: a boot, a red bag, a music box, a bike helmet, and a camera. You need three or more matching symbols to form a winning combination, with payouts ranging from 1.1x to 2.5x the stake for six matching symbols across the reels.

Beyond the regular symbols, a skull pierced by a wooden stake is the Wild, and an oxygen tank is the Bonus symbol. Six different Bomb symbols and colourful Gems displaying cash values complete the line-up, which we will explore later.

Features Overview

Who would have thought digging graves could be so time-consuming? Nolimit City has plenty planned for its latest underground venture, packing in features to keep even the most dedicated gravedigger busy. The line-up includes Reel Area & Cascading, Bombs, Gems, Gem Upgrades, The Descent Bonus, Extra Spin, Nolimit Booster, Feature Buy (Nolimit Bonus) and Nolimit Side Hustle..

Reel Area and Cascades

Grave digging isn’t quite as straightforward as it first appears, with random positions across the lower part of the grid buried beneath soil at the beginning of each spin. Hidden beneath are various symbols, including Bombs and Gems, waiting to be uncovered as the action progresses.

Winning combinations trigger a cascade, removing the contributing symbols, allowing those above to drop into the empty spaces. New symbols enter from the top, potentially creating further wins. Each successive cascade increases the Gems’ value, giving players another reason to keep digging.

Bombs

Grave digging takes an explosive turn, with six Bomb symbols that can clear dirt and symbols from the reels. Each has its own explosion pattern, determining how much of the grid is affected and what might be uncovered beneath the surface.

The six Bomb types are:

Small Box Bomb: Explodes across a 3×3 area.

Teddy Bear Bomb: Creates a cross-shaped explosion that extends up to two positions in each direction.

Big Box Bomb: Clears a larger 5×5 area of the grid.

Glass Can Bomb: Removes symbols and dirt across three complete rows.

Gasoline Bomb: Clears three complete columns.

Cake Bomb: Explodes across its entire row, column and both diagonals.

Depending on their positions, the explosions can uncover hidden Gems and other symbols, while clearing space for further cascades. Different blast patterns give each Bomb a distinct role, though the Cake Bomb is highly destructive when positioned toward the centre of the grid.

Gems

Six Feet Under holds more than dirt and buried belongings waiting to be discovered. Hidden beneath the surface are colourful Gems, each worth 1x, 2x, 3x, 5x, 10x, 20x, 50x, 100x, 200x, or 1,000x the stake.

The prizes become more valuable with every cascade, as each Gem increases by its original value. For example, a Gem starting at 5x increases to 10x after the first cascade, 15x after the second and 20x after the third.

However, uncovering these buried treasures requires a little explosive assistance. Bombs must clear the dirt concealing the Gems before players can collect their accumulated prizes.

Gem Upgrades

Not all buried treasure needs an explosion to increase its value. Six Feet Under introduces two additional features, the Shovel and Toolbox

The Shovel focuses on a single reel, adding more Gems and increasing the value of existing ones. The Toolbox extends the same treatment across all six reels, potentially increasing the number and value of Gems available for collection.

Both features offer more opportunities to increase the prizes hidden beneath the soil, though Bombs play an important role in uncovering them.

Descent Bonus

Landing three or more visible Oxygen Tank Bonus symbols triggers The Descent, but symbols still buried beneath the soil don’t count.

Unlike traditional Free Spins features, The Descent has no predetermined number of spins. The six-by-six grid begins completely empty, with regular symbols and soil appearing on each new drop. Soil stays in place throughout the bonus unless a Bomb explosion removes it, gradually filling the available spaces. Once all 36 positions are covered in soil, the bonus ends.

Additional Bonus symbols can improve the prizes available during The Descent. For each bonus symbol beyond the initial three, the lowest remaining Gem value is removed from those that are visible. For example, triggering the bonus with four Oxygen Tanks excludes all 1x Gems, while five removes both all 1x and 2x Gems. This continues with each additional Bonus symbol, increasing the minimum Gem value available during the round.

Bombs play an important role in Descent’s progression. They clear soil and open positions for more symbols to appear. The longer the grid remains partially uncovered, the more opportunities you have to discover valuable Gems before the final resting place fills.

Extra Spin

Not quite ready to call it a day? After a spin ends, you may randomly be offered an Extra Spin. Any dirt-covered symbols and visible Bonus symbols from the previous spin remain for the Extra Spin.

An Extra Spin is offered only when its price is equal to or lower than the total winnings from the previous round.

Nolimit Boosters

For those who fancy taking a shortcut with the digging, Six Feet Under offers six Nolimit Boosters. These optional purchases modify individual spins, with prices ranging from 3x to a rather eye-watering 3,000x the base bet.

The available options are:

Bonus Booster – 3x the bet: Guarantees an Oxygen Tank Bonus symbol hidden beneath the dirt.

Pure Spin – 8x the bet: Only Gems with a starting value of 5x or higher can land.

Purer Spin – 80x the bet: Raises the minimum starting Gem value to 50x.

Greedy Spin – 30x the bet: Guarantees every soil-covered position contains a Gem.

Greedier Spin – 300x the bet: Fills every soil-covered position with Gems worth at least 50x.

Greediest Spin – 3,000x the bet: Guarantees every soil-covered position contains a Gem worth 1,000x.

Feature Buy (Noliimt Bonus)

For those who would rather skip the digging and head straight into The Descent, Six Feet Under offers six Feature Buy options. Prices range from 60x to 2,965x the stake, with different starting conditions depending on the selected purchase.

The available options are:

60x the stake – The Descent (3 Bonus symbols): Guarantees entry into The Descent with three triggering Bonus symbols.

250x the stake – The Descent (5 Bonus symbols): Starts the bonus with five Bonus symbols, removing the two lowest Gem values.

600x the stake -The Descent (6 Bonus symbols): Guarantees six triggering Bonus symbols, excluding the three lowest Gem values.

1,900x the stake – The Descent (8 Bonus symbols) : Starts The Descent with eight Bonus symbols, eliminating the five lowest Gem values.

260x the stake – Lucky Draw: Randomly selects a bonus configuration rather than guaranteeing a particular number of Bonus symbols.

2,965x the stake – Lucky Draw 2 offers a separate random selection weighted towards higher-value bonus configurations.

Due to UK regulations, British players can’t access Boosters or Feature Buy options.

Verdict

Nolimit City has never been afraid to explore the darker side of slot development, although Six Feet Under doesn’t quite reach the disturbing heights of some of its previous creations. The underground setting fits the storyline, but the subdued presentation lacks the visual impact we’ve come to expect from a developer with such a provocative reputation.

Fortunately, there’s more going on beneath the surface. The combination of explosive symbols, increasingly valuable Gems and an unconventional bonus round gives Six Feet Under plenty of depth, especially for players who appreciate Nolimit City’s complex mechanics. Extreme volatility and a maximum win of 30,000x the stake appeal to players comfortable with unpredictable results and potentially long dry spells between big payouts.

Visually, Six Feet Under might not be one of Nolimit City’s most memorable creations, but there’s enough beneath the soil to warrant a closer look. And if the grave digger offers to help, run a mile in the opposite direction!
