Six Feet Under: Digging for Gems

Six Feet Under is a Nolimit City slot released on 20 October 2026, after an exclusive early access period that began on 13 October 2026. It plays on 6 reels with 6 rows and uses cascading reels: winning symbols explode and new ones fall into place, which can award further wins.

The twist is underground. On every spin, positions on the bottom rows are randomly filled with dirt, and some of those dirt positions hide a symbol: a Bonus symbol, a Bomb or a Gem. Nothing buried pays until something digs it out.

The theme matches the name. The game's lead character makes friends badly, and his friendships tend to end with the other person in the ground, and Nolimit City frames it as Best Friends Forever, with the forever taken literally.

Nolimit City lists the RTP at 96.05% and the hit frequency at 21.90%, so roughly one spin in five returns a win. The game page names volatility as a field but shows no figure for it in text.

The max payout is 30,000 times the base bet. Nolimit City puts the probability of reaching it at 1 in 93m and the odds of triggering the free spins at 1 in 233 spins.

Bets run from €0.20 to €100.00 per spin. The page confirms a feature buy-in and a bonus mode, both covered below.

Dirt is the game's defining layer. It sits on the bottom rows at the start of each spin, and only Bombs clear it, so the symbols hidden beneath it stay locked until an explosion reaches them.

Above the dirt, the game plays as a cascading slot. Winning symbols are removed, new symbols drop in, and every drop is a fresh chance for a win or for a Bomb to land where it can do damage.

The Wild symbol substitutes for any other paying symbol, helping to form the wins that keep a cascade sequence going.

Bombs remove paying symbols and dirt in a pattern that depends on their type, and six types can land. The Small Box Bomb clears a 3x3 area and the Big Box Bomb clears a 5x5 area.

The Teddy Bear Bomb explodes in a cross, removing up to 2 symbols in each of the four directions. The Glass Can Bomb clears its own row plus the rows directly above and below, while the Gasoline Bomb does the same for its own column and the columns either side.

The Cake Bomb is the widest pattern: it removes everything in its row, its column and both diagonals passing through its position. On a 6x6 grid, a well-placed Glass Can, Gasoline or Cake Bomb can reach dirt right across the board.

Gems are where the money is. Each Gem has a value, and when a Bomb removes the dirt covering it, that value is multiplied by the base bet and paid.

Gem values grow while they wait. At the start of each avalanche, every Gem's value increases by its base value, and the possible base values are 1x, 2x, 3x, 5x, 10x, 20x, 50x, 100x, 200x and 1,000x. As an illustration of that rule, a Gem with a 5x base that sits through three avalanche starts would have grown by 15x before being uncovered.

The Shovel adds Gems. When it lands it removes itself, places random Gems in empty dirt positions on its reel and upgrades Gems already on that reel to a higher multiplier. The Toolbox does the same across all reels at once.

The Descent is the Nolimit Bonus, triggered by landing 3 Bonus symbols. Bonus symbols still buried in dirt do not count towards the trigger, so a Bomb has to free them first or they need to land in the open.

The round starts with an empty reel area. Each new drop adds dirt symbols as well as regular symbols, and that dirt is sticky. The round ends when the reel area has filled with dirt, so the bonus lasts as long as Bombs and wins keep clearing space.

Extra Bonus symbols improve the round. For each Bonus symbol above 3 that helps trigger it, the next lowest value Gem type cannot land during The Descent, so a 4-Bonus trigger takes the lowest Gem type out of the round from the first drop.

Six Nolimit Boosters are listed. Bonus Booster costs 3 times the base bet and guarantees a Bonus symbol hidden beneath the dirt.

Pure Spin, Purer Spin 50x and Greedy Spin are each described on the game page with the same wording: a cost of 8 times the base bet, with only Gems of a base value of 5x or higher able to land. Their names suggest they differ, so check the in-game rules for the exact effect of each before comparing them.

Greedier Spin costs 300 times the base bet and fills every dirt position with Gems worth 50x or more. Greediest Spin costs 3,000 times the base bet and fills every dirt position with Gems worth 1,000x.

Side Hustle is an optional add-on that raises the cost of a spin in return for a fixed win if a chosen outcome happens, paid on top of other wins. Several can be placed at once, and the cost and payout depend on the bet chosen.

There is one Side Hustle for each Bomb type exploding. The others pay if The Descent runs to at least 12 free spins, if a spin ends with no dirt left, or if a base game spin ends with no win at all.

xTra may offer an extra spin to buy when a round ends. It keeps every dirt symbol that holds a symbol, plus any Bonus symbols from the previous spin, and it is priced on the active feature and the remaining symbols. It is offered only when its cost is no more than the total win.

The Happy Birthday rule caps the game: once the total win passes 30,000 times the base bet, the round ends and the capped amount is paid.

Nolimit City offers a free demo of Six Feet Under on its own game page. Watch the bottom rows first: count the buried symbols at the start of each spin and see which Bombs land close enough to reach them.

Track Gem values across a cascade sequence. Because each Gem grows by its base value at every avalanche start, a long chain of wins above the dirt can be worth more than an early Bomb that uncovers Gems at their starting value.

In The Descent, note how quickly sticky dirt fills the grid and how often Bombs clear it. With a listed hit frequency of 21.90%, most spins return nothing, and a demo session shows how the rules work, not what a future spin will pay. Play is for adults aged 18 and over only.

Land 3 Bonus symbols to trigger The Descent, Nolimit City's free spins bonus, which it lists at odds of 1 in 233. Bonus symbols still buried in dirt do not count.

How do Gems work in Six Feet Under?

Each Gem hides under dirt with a base value of 1x to 1,000x. At the start of every avalanche, each Gem's value rises by its base value, and when a Bomb clears the dirt above it, the value is multiplied by the base bet and paid. Shovels and Toolboxes add Gems and upgrade existing ones.
