Six Feet Under is a dark burial story: one minute you're his new best friend, the next you've got your own little spot in the ground six feet under.

The game runs on 6 reels with 6 rows. On each spin, positions on the bottom rows fill at random with dirt, and some dirt hides Bonus symbols, Bombs or Gems. Winning symbols explode and new ones fall into place, which can award more wins. Wilds substitute for any paying symbol.

Bombs remove paying symbols and dirt. Nolimit City lists six: the Small Box Bomb (3x3), Teddy Bear Bomb (a cross), Big Box Bomb (5x5), Glass Can Bomb (3 rows), Gasoline Bomb (3 columns) and Cake Bomb (row, column and both diagonals). When a Bomb clears the dirt over a Gem, the Gem pays its value times the base bet, and every Gem's value rises by its base value at the start of each avalanche. Base values run from 1x to 1,000x. A Shovel adds and upgrades Gems on its reel; a Toolbox does it on all reels.

Three Bonus symbols start The Descent (Bonus symbols still under dirt do not count). The reel area starts empty, each new drop adds sticky dirt, and the round ends when the reels are full of dirt. Each Bonus symbol above three removes the next lowest-value Gem type from the round. Optional extras include Side Hustle add-on bets and xTra, an extra spin offered at the end of a round. What your casino offers can vary by market.
