Dig Your Way to a 30,000x Max Win With Six Feet Under
If you're looking for a cheerful slot to brighten your day, Six Feet Under probably isn't the one to choose. NoLimit City has taken a decidedly darker approach with this underground adventure, where dirt-covered reels, unsettling imagery and a collection of explosive devices set the scene for some seriously unpredictable gameplay. It's grim, it's grubby, and it certainly isn't short on personality.
Fortunately, there's more to this slot than its macabre setting. Played on a 6x6 grid with up to 46,656 ways to win, Six Feet Under revolves around uncovering valuable Gems by blowing away the dirt that conceals them. Different Bombs clear different sections of the grid, while cascading wins increase Gem values and create opportunities for further rewards.
With an extremely volatile mathematical model and a maximum win of 30,000x your stake, this is a game that takes you on a potentially rewarding, if decidedly risky, underground expedition.

How to Play Six Feet Under
Six Feet Under takes a different approach to slot gameplay. Rather than relying solely on matching symbols across fixed paylines, it uses a 6x6 grid with up to 46,656 ways to win. Winning combinations are formed by matching symbols across adjacent reels, starting from the leftmost reel, with the number of possible combinations depending on the symbols available on each reel.
There's a catch, though: parts of the grid can be covered in dirt. These blockers appear randomly on the lower rows at the start of each spin, obscuring positions that might otherwise contain useful symbols. Some dirt-covered positions conceal regular symbols, while others hide Bombs, Scatters or Gems.
That's where the explosives come in. When a Bomb detonates, it clears dirt and symbols in a particular pattern, potentially exposing valuable Gems or creating new winning combinations. Winning symbols are removed through the cascading mechanic, allowing new symbols to fall into the grid for another chance to win.
Gems are particularly important because they carry monetary values that can be collected when the dirt covering them is removed by a Bomb. Their values can also increase as the game progresses through avalanches, giving you a reason to pay attention to what lies beneath the surface.
However, Six Feet Under is an extremely volatile slot. You might uncover valuable Gems and trigger a rewarding sequence, or spend several spins shifting dirt without much to show for it. The potential rewards are substantial, but the unpredictable nature of the game means it's worth approaching with a clear budget.
Six Feet Under Symbols & Payouts
Six Feet Under has a selection of conventional paying symbols, but the more interesting elements are the special symbols and hidden items that drive its gameplay.
Low-Paying Symbols
The lower-paying symbols consist of card ranks from 10 through Ace. They're presented in a ransom-note style that fits the game's unsettling atmosphere.
Landing six matching royal symbols pays between 0.5x and 0.9x your stake, depending on the symbol. These payouts are relatively modest, so the real attraction lies in the higher-paying symbols and the special features that can uncover Gems.
High-Paying Symbols
The premium symbols include boots, a backpack, a music box, a helmet and a camera.
A six-of-a-kind combination of these symbols pays between 1.1x and 2.5x your stake, depending on the symbol involved. While they offer better payouts than the card ranks, they're not the main reason to play Six Feet Under.
Instead, much of the excitement comes from the Bombs, Gem values and cascading sequences that can turn an ordinary-looking spin into something more rewarding.
Wild Symbols
Wild symbols substitute for all regular paying symbols, helping you complete winning combinations.
They're useful for creating wins on the 6x6 grid, although the game's main attraction is its collection of Bombs and Gems. These mechanics give Six Feet Under a more distinctive identity than a conventional slot built around matching symbols.
Scatter Symbols
Scatter symbols are used to trigger The Descent bonus round. Landing three Scatters in the base game activates the feature, but there's an important detail to remember: Scatters hidden beneath dirt don't count towards triggering the bonus.
The Descent has its own rules, with dirt gradually filling the grid until the round ends. The number of Scatters involved in triggering the feature can also influence which Gem values are available during the bonus.
Gem Symbols
Gems are the stars of Six Feet Under. Each Gem has a base value of 1x, 2x, 3x, 5x, 10x, 20x, 50x, 100x, 200x or 1,000x your stake.
These values are awarded when a Bomb explosion removes the dirt covering a Gem. At the start of each avalanche, every Gem's value increases by its base value, creating the potential for more valuable collections as the sequence continues.
The higher-value Gems are particularly important because they can contribute significantly to the game's maximum win potential. However, finding them is only part of the challenge. You also need the right Bombs and feature interactions to uncover them.
Six Feet Under Bonus Features
NoLimit City has packed Six Feet Under with features that revolve around destruction, collection and increasing Gem values. The Bombs are the main attraction, but Gem Upgraders, The Descent and several optional extras give you different ways to approach the game.
Bomb Symbols
Bombs are central to the gameplay, and each type has a different explosion pattern. Rather than simply removing a single symbol, these explosives clear specific areas of the grid, potentially revealing hidden Gems and removing dirt blockers.
There are six Bomb types in total.
| Bomb Type | Explosion Pattern | What It Does |
|---|---|---|
| Small Box Bomb | 3x3 area | Clears a square section around the Bomb |
| Teddy Bear Bomb | Cross pattern | Removes up to two symbols in each of the four directions |
| Big Box Bomb | 5x5 area | Clears a larger square area |
| Glass Can Bomb | Three rows | Removes symbols in its row and the rows immediately above and below |
| Gasoline Bomb | Three columns | Removes symbols in its column and the adjacent columns |
| Cake Bomb | Plus and diagonal patterns | Clears its row, column and both diagonals passing through its position |
The different explosion patterns help keep the gameplay varied. A Small Box Bomb clears a relatively compact area, while a Big Box Bomb can affect a much larger portion of the grid. Other Bombs focus on rows, columns or diagonal lines.
The important thing is what these explosions uncover. Clearing dirt can reveal Gems and other useful symbols, while removing paying symbols can also contribute to the cascading action.
Of course, an explosion doesn't guarantee a valuable reward. The grid might contain something worthwhile beneath the dirt, or the Bomb might simply clear space without producing a significant payout. That uncertainty is part of what makes Six Feet Under such a volatile experience.
Gems & Cascading Wins
Gems are more than decorative items in Six Feet Under. They carry values that can be awarded when Bomb explosions remove the dirt covering them, making them a key part of the game's reward system.
The available base values range from 1x to 1,000x your stake. At the lower end, the Gems offer relatively modest rewards, while the highest-value types have the potential to contribute considerably more.
The cascading mechanic adds another layer to the process. When winning combinations land, the paying symbols are removed and new ones fall into the grid. At the start of each new avalanche, the base value of every Gem increases its current value.
This means that a sequence of cascades can make the Gems more valuable as the action continues. The longer a useful sequence develops, the more opportunities you may have to uncover Gems with increased values.
However, the game doesn't guarantee a long cascade or a valuable collection. You'll need the right combination of symbols, Bomb explosions and Gem values to see the feature pay off.
Gem Upgraders: Shovel & Toolbox
Not every useful feature in Six Feet Under involves blowing things up. The game also includes two Gem Upgraders that can improve the values available on the grid.
The first is the Shovel. When this symbol lands, it removes itself and adds random Gem symbols to empty dirt positions on the same reel. Any Gems already present on that reel are upgraded to Gems with higher values.
The Toolbox works in a similar way, but its effect extends across all reels rather than being limited to one.
These features give you another way to improve the grid's potential without relying entirely on Bomb explosions. Adding Gems to empty dirt positions can create new opportunities for collection, while upgrading existing Gems increases their potential value.
The distinction between the two is straightforward: the Shovel focuses on one reel, whereas the Toolbox affects the entire grid.
The Descent Bonus Round
Landing three Scatter symbols in the base game triggers The Descent, Six Feet Under's main bonus round. Remember that Scatters hidden beneath dirt don't count towards triggering the feature.
The bonus begins with an empty grid. As new drops occur, dirt symbols and regular symbols are added to the playing area. The dirt symbols are sticky, meaning they remain in place as the round progresses.
The Descent continues until dirt fills the reel area, bringing the feature to an end. Throughout the round, the aim is to uncover valuable Gems and make the most of the available opportunities before the grid becomes completely blocked.
There's also a connection between the number of Scatters involved in triggering the feature and the Gem values available. For each additional Scatter above the initial three that contributes to triggering The Descent, the next-lowest Gem value is excluded from the bonus.
This means that triggering the feature with additional Scatters can remove some of the lower-value Gem types from the selection. However, it doesn't guarantee that you'll collect a high-value Gem or achieve a substantial payout.
The Descent is a fitting centrepiece for the game. The grid gradually fills with dirt, adding pressure as the round progresses, while the hidden Gems give you a reason to keep watching for valuable discoveries.
Extra Spins
Six Feet Under also offers an Extra Spins feature that may give you the opportunity to buy another spin when a round ends.
The additional spin retains dirt symbols containing symbols, along with any Scatters from the previous spin. Its cost is calculated based on the active feature and the symbols remaining on the grid.
There's a condition attached, though. You'll only be offered the Extra Spin when its cost is less than or equal to your total win.
This feature can give you another chance to continue a promising sequence or make use of the symbols already on the grid. However, the cost depends on the situation, so it's important to check the amount before deciding whether to continue.
NoLimit Boosters & Bonus Buys
If you prefer to take a more direct approach, Six Feet Under includes several optional features that let you influence the symbols or bonuses available.
The options vary considerably in price and purpose, ranging from a relatively inexpensive Booster to high-cost spins focused on valuable Gems.
| Feature | Cost | Effect |
|---|---|---|
| Bonus Booster | 3x your stake | Guarantees a Scatter hidden beneath the dirt |
| Pure Spin | 8x your stake | Only Gems worth 5x or more can land |
| Purer Spin | 80x your stake | Only Gems worth 50x or more can land |
| Greedy Spins | 30x your stake | Fills all dirt positions with Gems |
| Greedier Spins | 300x your stake | Fills all dirt positions with Gems worth 50x or more |
| Greediest Spins | 3,000x your stake | Fills all dirt positions with Gems worth 1,000x |
These options let you choose between different approaches. The Bonus Booster focuses on improving access to The Descent, while Pure Spin and Purer Spin exclude lower-value Gems from the available selection.
The Greedy Spins options take things further by filling the dirt positions with Gems. The more expensive versions focus on progressively higher values, with Greediest Spins offering Gems worth 1,000x your stake.
Six Feet Under also offers paid entry options for The Descent and Lucky Draws, with listed prices ranging from 60x to 2,965x your stake, depending on the option selected.
These features can be tempting, particularly when you're aiming for the higher-value Gems, but their prices can be substantial. A feature buy doesn't guarantee a profit, and the cost of entry can be lost if the resulting outcome isn't favourable.
Side Hustles
Side Hustles are optional side bets that sit on top of your regular stake. Each one is tied to a particular outcome, such as a specific Bomb exploding or a certain event occurring during The Descent.
If the required condition is met, the side bet pays a predetermined multiple. If it isn't, the side bet doesn't pay.
Here's a breakdown of the available options.
| Side Hustle | Additional Cost | Payout if the Condition Is Met |
|---|---|---|
| Explode Small Box Bomb | 2x your stake | 20.55x |
| Explode Teddy Bear Bomb | 2x your stake | 22.9x |
| Explode Big Box Bomb | 0.8x your stake | 42.5x |
| Explode Glass Can Bomb | 0.8x your stake | 41.85x |
| Explode Gasoline Bomb | 0.6x your stake | 61.4x |
| Explode Cake Bomb | 0.6x your stake | 60.85x |
| 12 Freespins | 0.8x your stake | 532.55x |
| No Dirt | 0.1x your stake | 136.3x |
| Dead Spin | 10x your stake | 12.25x |
The Bomb-related options pay when the specified Bomb explodes. The 12 Freespins side bet pays if the total number of spins in The Descent reaches at least 12, while No Dirt pays if the spin ends without any dirt remaining.
Dead Spin is a little different, paying when a base-game spin finishes without a win.
These bets add another layer to the gameplay, allowing you to target particular outcomes. However, they also increase the amount you're staking, so it's worth weighing up the additional cost before activating any of them.

Six Feet Under RTP, Volatility & Win Potential
Six Feet Under is built for players who don't mind taking a few risks. Its mathematical model is classified as extremely volatile, which means results can vary considerably, with potentially long stretches of limited returns alongside the possibility of much larger wins.
The slot's highest stated RTP is 96.05%, although three RTP configurations are available. RTP, or return to player, represents the theoretical proportion of total stakes returned to players over a very large number of spins. It doesn't tell you what you'll win during a particular session, and the version available at your casino may have a different RTP.
The maximum win is 30,000x your stake, giving Six Feet Under substantial payout potential. The Gem system is central to this, with values reaching 1,000x your stake before the effects of the game's cascading mechanics and other features are considered.
Bombs can expose hidden Gems, Gem Upgraders can increase their values, and cascades provide opportunities for those values to grow. When the right elements come together, the result can be a substantial payout.
However, the extremely volatile nature of the game means there's no guarantee that these features will produce a big win. You might uncover valuable Gems, or you might spend several spins clearing dirt without much reward.
The feature buys and Side Hustles also deserve careful consideration. Some options cost hundreds or even thousands of times your stake, making them particularly expensive ways to access specific outcomes.
Our advice: If you enjoy high-risk slots, set a firm budget before playing and treat the maximum win as a possibility rather than an expectation. The game's biggest payouts may be eye-catching, but they shouldn't be the basis for deciding how much to stake.
Playing Six Feet Under on Mobile
Six Feet Under's 6x6 grid gives it plenty of room for symbols, dirt blockers and explosive effects. On a mobile screen, being able to identify the different Bomb types and understand which parts of the grid they affect is particularly important.
You'll also want to keep an eye on Gem values, as these can change during cascading sequences. The various feature-buy options and Side Hustles add further details to consider, making it useful to familiarise yourself with the rules before playing.
However, specific information about mobile optimisation, device compatibility and performance hasn't been provided for this review. Check the game through a compatible casino on your own device to see how its controls and presentation work on your screen.
Six Feet Under Slot Review: Final Verdict
Six Feet Under is a decidedly different kind of slot. NoLimit City has created a grim underground world where Bombs, dirt blockers and hidden Gems take centre stage, giving the game a clear identity that sets it apart from more conventional releases.
The Bomb mechanics are the main attraction. With six different explosion patterns, each capable of clearing a different part of the grid, there's plenty to consider as you try to uncover valuable Gems. The cascading system adds another layer by increasing Gem values as avalanches progress, while Gem Upgraders provide further opportunities to improve what's available on the grid.
The Descent bonus round fits the theme particularly well, gradually filling the grid with sticky dirt until the action comes to an end. The various Boosters, bonus buys and Side Hustles also give experienced players plenty of options, although some of these come with very high price tags.
The biggest drawback is the game's presentation. While the underground setting is suitably unsettling, the visuals are relatively drab, and the Gems themselves don't look particularly impressive. The extremely volatile gameplay also means that the experience can be unpredictable, with no guarantee that you'll uncover anything especially valuable.
Still, Six Feet Under has enough going on to appeal to players who enjoy unconventional mechanics and high-risk gameplay. Its 30,000x maximum win provides a substantial target, while the Bombs and Gem collection system give the game a distinctive hook.
Our verdict: Six Feet Under is a grim, explosive slot with an interesting approach to Gem collection and some serious payout potential. The presentation could be stronger, and the extreme volatility won't suit everyone, but players who enjoy NoLimit City's darker creations may find plenty to dig into.
