Nolimit City’s Six Feet Under: A 6×6 Slot Where Bombs Blast Away Dirt to Dig Up Gems
Six Feet Under, released by Nolimit City on October 20, is a slot where bombs blast away the dirt covering the lower part of the grid to dig up hidden gems. It features six bomb types, The Descent bonus where dirt slowly fills the reels, and xTra Spin, with a max win of 30,000x the bet.
Key Takeaways
- After an exclusive early access period from October 13, 2026, it officially launched on October 20.
- 6 reels and 6 rows, RTP 96.05%, hit frequency 21.90%, and a max win of 30,000x the bet.
- Gems covered by dirt only pay once a bomb explodes and clears the dirt, and their value rises with every avalanche.
- The Descent bonus runs until dirt covers the whole grid, and by the official figures it triggers about once every 233 spins.
The October release from Nolimit City is the story of a man who wants to keep his friends close ‘forever’. The official launch post introduces the game by noting that nobody thought to ask what he meant by ‘forever’. As the title suggests, the setting is six feet underground.
What Kind of Game Is Six Feet Under?
The grid has 6 reels and 6 rows. On each spin, some positions on the bottom rows are randomly covered with dirt, and that dirt can hide Bonus symbols, bombs or gems. The base mechanic is cascading reels, where winning symbols explode and new ones drop in, and the wild substitutes for other paying symbols.
| Release date | October 20, 2026 (early access October 13) |
|---|---|
| Reel layout | 6×6, cascading |
| RTP | 96.05% (base game 60.41% + bonus 35.64%) |
| Hit frequency | 21.90% |
| Max win | 30,000x the bet (about 1 in 93 million) |
| Bet range | 0.20 – 100 |
| Bonus buy | Available (Nolimit Boosters) |
What stands out is that 60.41% of the 96.05% RTP comes from the base game. Rather than packing the returns into the bonus, the design pays back steadily through bombs and gems in the base game.
What Makes It Feel Like Nolimit City?
First, the theme. The official launch post itself says the game deals with yet another disturbed mind, following Mental II and Serial. Nolimit City’s Head of Product, Lars Söderberg, explained that the team wanted to explore a much darker side of friendship and ended up with something fairly disturbing. The presentation is grim, but the tone is closer to black comedy.
Second, the choice that comes after a round ends. Of Nolimit City’s signature x features, the one in this game is xTra Spin. When a round ends, you may be offered one more spin that keeps the dirt positions holding symbols and any Bonus symbols in place. The price depends on the remaining symbols and the active feature, and the offer only appears when that price is no higher than the round’s win. Reel-based xMechanics such as xWays or xBomb are not used.
Third, Side Hustle. It is an optional add-on bet that raises the spin cost to bet on a specific outcome, with 9 options including each of the six bomb types exploding, The Descent reaching 12 or more total spins, a spin ending with no dirt, and a base game spin with no win, and several can be placed at once. The history of the xMechanics is laid out in our full analysis of Nolimit City xMechanics.
How Do Bombs and Gems Work Together?
There are six bomb types, and each explodes in a different pattern. The Small Box Bomb clears 3×3, the Teddy Bear Bomb clears a cross reaching up to 2 positions in each direction, and the Big Box Bomb clears 5×5. The Glass Can Bomb clears 3 rows, its own and the ones above and below, while the Gasoline Bomb clears 3 reels, its own and the ones to the left and right. The Cake Bomb clears its row, its column and both diagonals at once.
When an explosion clears the dirt, the gem underneath is revealed and pays its value multiplied by the base bet. Gem base values come in 10 tiers: 1x, 2, 3, 5, 10, 20, 50, 100, 200 and 1,000x. At the start of each new avalanche, every gem’s value grows by its own base value, so the longer a cascade runs before the dirt is cleared, the more the gems are worth. The Shovel fills empty dirt positions on its reel with gems and turns existing gems into higher-multiplier gems, and the Toolbox does the same across all reels.
How Do You Get Into the Bonus?
Three Bonus symbols start The Descent spins. It matters that Bonus symbols buried under dirt do not count. By the official figures, the bonus opens about once every 233 spins.
The Descent starts from an empty grid. With every drop, sticky dirt lands along with regular symbols, and the round ends when the grid is full of dirt. Each Bonus symbol beyond 3 removes the lowest gem type, so triggering with 4 means no 1x gems, and with 5 there are no 2x gems either.
The bonus buy comes in the form of Nolimit Boosters. The Bonus Booster at 3x the bet guarantees a Bonus symbol hidden under the dirt, and the Pure Spin at 8x lets only gems with a base value of 5x or more land. According to the official game page, the Greedier Spin fills every dirt position with gems of 50x or more for 300x, and the Greediest Spin fills every dirt position with 1,000x gems for 3,000x.
Who Is It For?
A hit frequency of 21.90% means something lands roughly once every five spins. However, wins of 100x or more come about once every 663 spins, and the 30,000x max win is about 1 in 93 million. The official launch post also rates the game as ‘Extremely Volatile’. Small wins come often, but the big results are concentrated in the moments when dirt full of built-up gems is cleared all at once.
That makes it a fit for players who enjoy the bomb explosions themselves and like watching gem values swell with every cascade. If the digging theme feels familiar, it is worth comparing with Fire in the Hole or Misery Mining from the same studio. On the other hand, players who want to see the bonus often in a short session may find the swings large.
Can You Try It in the Demo First?
Six Feet Under is already officially released, so you can play the free demo on AI Slot right away with no sign-up. Spending the first few hundred spins watching which bombs explode over which gems, and how fast the dirt fills up in The Descent, is a quick way to understand the structure. This game is also one of the titles in the Nolimit City Max Win Legend posters program.
Mental II and Serial, both mentioned in the official launch post, share the same dark subject matter. More games from Nolimit City are gathered on Nolimit City free slots.
