Six Feet Under

Six Feet Under comes from Nolimit City, a provider known for building its releases around dark settings, and this slot follows that pattern. It includes a variety of special symbols and features designed to create more winning possibilities, with the aim of making sessions more rewarding and enjoyable.

Gameplay Features and Bonuses

Six Feet Under runs on a 6×6 grid with up to 46,656 ways to win, an RTP of 96.05%, high volatility, and a maximum win of 30,000x the bet. Most of its features revolve around one idea. Dirt covers part of the grid, valuable symbols hide beneath it, and the player needs explosions to uncover them.

Dirt on the Reels: At the start of every spin, random positions on the bottom rows fill with dirt. Some of these dirt positions conceal a symbol, which can be a Bonus symbol, a Bomb, or a Gem. Whatever sits underneath stays hidden until something clears the dirt above it.

Cascading Reels: Winning symbols explode and disappear after each win, and new symbols fall into the gaps. Every cascade can produce another win, and the sequence continues until no new combinations form.

Wild Symbol: The Wild stands in for any paying symbol.

Bombs: Bombs are the main tool for clearing dirt. When one explodes, it removes paying symbols and dirt in a pattern that depends on its type.

• Small Box Bomb: Clears a 3×3 area.
• Teddy Bear Bomb: Clears a cross shape, reaching up to 2 positions in each of the four directions.
• Big Box Bomb: Clears a 5×5 area.
• Glass Can Bomb: Clears its own row plus the rows directly above and below.
• Gasoline Bomb: Clears its own column plus the columns on each side.
• Cake Bomb: Clears its full row, its full column, and both diagonals that pass through it.

Gems: Each Gem has a base value of 1x, 2x, 3x, 5x, 10x, 20x, 50x, 100x, 200x, or 1,000x. A Gem only pays when a Bomb removes the dirt covering it, at which point its value is multiplied by the base bet and awarded. Gems also grow during a sequence, since every new avalanche adds the base value again to each Gem’s current value. A Gem that stays buried through several cascades is therefore worth more once it is finally exposed.

Shovel: The Shovel removes itself from the grid and places random Gems into empty dirt positions on its reel. Any Gems already on that reel are upgraded to a higher multiplier.

Toolbox: The Toolbox follows the same rules as the Shovel, but it affects every reel at once.

The Descent: 3 Bonus symbols trigger The Descent, provided all three are visible. Bonus symbols still hidden under dirt do not count toward the trigger. The round starts with an empty grid. Each new drop brings regular symbols along with dirt, and the dirt is sticky, so the grid gradually fills up.

The Descent ends once every position is covered in dirt. Each Bonus symbol beyond the first three also removes the next lowest Gem value from the round, which leaves only higher-value Gems available to land.

Nolimit Boosters: The game offers several paid options, each with a fixed cost based on the base bet.

• Bonus Booster: Costs 3x the bet and guarantees a Bonus symbol hidden beneath the dirt.
• Pure Spin: Costs 8x the bet and allows only Gems with a base value of 5x or higher to land.
• Purer Spin: Costs 80x the bet and allows only Gems with a base value of 50x or higher to land.
• Greedier Spin: Costs 300x the bet and fills every dirt position with Gems worth 50x or more.
• Greediest Spin: Costs 3,000x the bet and fills every dirt position with Gems worth 1,000x.

Side Hustle: Side Hustle is an optional add-on bet that raises the total cost of a spin. The player picks a specific outcome to bet on, and if it happens, a fixed win is paid in addition to any other wins from that spin. Both the cost and the payout depend on which outcome is chosen, and players can run several Side Hustles at the same time. The game offers nine Side Hustle options:

• Explode Small Box Bomb: Pays if a Small Box Bomb goes off during the spin.
• Explode Teddy Bear Bomb: Pays if a Teddy Bear Bomb goes off during the spin.
• Explode Big Box Bomb: Pays if a Big Box Bomb goes off during the spin.
• Explode Glass Can Bomb: Pays if a Glass Can Bomb goes off during the spin.
• Explode Gasoline Bomb: Pays if a Gasoline Bomb goes off during the spin.
• Explode Cake Bomb: Pays if a Cake Bomb goes off during the spin.
• 12 Free Spins: Pays if The Descent reaches a total of at least 12 spins.
• No Dirt: Pays if the spin finishes with no dirt left on the grid.
• Dead Spin: Pays if a base game spin finishes with no win.

xTra Spin: When a round ends, the player may be offered one extra spin for a price. The extra spin keeps every dirt position that holds a symbol, along with any Bonus symbols from the previous spin. Its cost depends on the active feature and the symbols remaining, and the offer only appears if that cost is equal to or lower than the total win.

Happy Birthday: The maximum payout is 30,000x the base bet. If the total win goes beyond that amount, the round ends and 30,000x is awarded.

Design and Soundtrack

The action takes place in an underground tunnel. Its dark brown dirt walls are crossed by pipes running through the middle, and crystals show through the soil in scattered spots. The card ranks from 10 to A are written on scraps of paper, which suits the improvised feel of the setting.

The other symbols are items an explorer might carry or leave behind, including boots, backpacks, music boxes, helmets, and cameras. The soundtrack matches the underground atmosphere and keeps the mood consistent throughout.

Disorder and Bangkok Hilton are two other Nolimit City titles worth trying for players who want a similar setting and comparable gameplay mechanics.

The Bottom Line

Six Feet Under rewards patience more than quick hits, because Gems gain value with every avalanche but only pay once a Bomb clears the dirt above them. That link between Bombs and buried Gems drives most of the larger wins, and the Shovel and Toolbox add more Gems to the same chain. The Descent works on a closing clock, with sticky dirt filling the grid until the round ends, so extra Bonus symbols that remove low Gem values matter a great deal. High volatility and a 30,000x maximum win fit that design, and Boosters from 3x to 3,000x let players choose their level of risk.
