What is the Doom's Digging Machine slot?

Doom's Digging Machine slot graphics and theme

Octoplay opted for a cartoon-style approach to the titular character, Doom, like a villain from a Saturday morning television show. He has a rectangular head shape, disproportionately long arms and large hands. The symbols are stylised gems and fossils with magical animations for when they’re part of a winning combination.

How to play Doom's Digging Machine slot: Features, symbols, and gameplay

Playing Doom’s Digging Machine follows a traditional gameplay loop of clicking the spin button to place a bet. Every win keeps the tumble feature going, extending the round. All payouts are accumulated for a full spin and then paid at the end. 

Paylines

There is no payline in Doom’s Diggling Machine. Symbols can be placed anywhere on the grid and count as part of the winning combination if there are 8 or more of them simultaneously.

Symbols

Low-paying Symbols

Low-paying symbols in Doom’s Digging Machine are gems with rocky frames. Each one has a distinct colour and shape to set them apart from each other. They look refined and processed, compared to high-paying symbols. 

Here are the values of each gem from least to most valuable in Doom’s Digging Machine:

High-paying Symbols

Whilst low-paying symbols look refined or processed, the high-paying symbols show natural, unpolished minerals. Rather than identifying them by shapes or colours, Doom’s Digging Machine presents them with different fossils for scale. 

Here are the high-paying symbols and their values per set in Doom’s Digging Machine:

Scatter symbol

The scatter symbol in Doom’s Digging Machine is an image of the titular character laughing maniacally while pressing a big red button. Get at least 3 of them in a single spin, and you trigger the game's Free Spin bonus. The initial reward is 10 free spins, but each additional scatter symbol adds 5 more, up to a maximum of 30.

The Doom’s Digging Machine free spin bonus feature can also show the scatter symbol. Each one adds 1 more for a total of 10 max in a single spin. You also grow the global multiplier equal to the number of additional free spins won. 

Mystery Artefact

The Mystery Artefact only appears during the free spins mode. It’s usually taking up 2x2 or 3x3 positions in the grid with either 3x or 5x written on it. The number is added to your global multiplier, and if the Mystery Artefact breaks, it will reveal a cluster of any normal symbol. 

Doom's Digging Machine bonus rounds and free spins

The Doom’s Digging Machine bonus feature still uses the same grid, but the top screen now shows the global multiplier. It still features the same game mechanics as the base game, except every Scatter Mode that appears adds 1 free spin to the game mode. 

Tumble Feature

The Tumble Feature is present in both the base game and free spin bonus modes. Every winning combination disappears from the grid, and new symbols fall to fill the vacant spots. The Global Multiplier is applied to each hit before being accumulated for the total payout. 

Buy Feature

Pressing the Buy Feature on the bottom right, next to the spin button, opens a window offering the opportunity to instantly trigger the Free Spin bonus. It will give you at least 3 guaranteed scatter symbols to guarantee 10 free spins. This will still trigger the Tumble Feature and give you a payout if there’s a winning set in the spin.
