Octoplay released Doom’s Digging Machine on July 12 2024. The slot has a mining theme where you go on a journey to gather precious minerals. 

This review will teach you about the game setup and bonus features.

Game setup 

Once you open the game, you will notice 5 reels and 6 rows. Winning combinations are determined by scatter pays on a default RTP of 96.7%.

To get going, you must place a minimum bet of €0.10 or a maximum bet of €200 for a shot at the maximum win on low/medium volatility. The maximum win is worth 5000x.

Winning combinations are made up of 9 regular paying symbols. The symbols are a diamond, triangle, heart, pentagram and octagonal shapes. The other symbols are a bone hand holding a gem and three gem-encrusted skulls. 

Landing 8 matching symbols rewards 0.2x to 10x while landing 12 or more matching symbols rewards 2x to 50x. 

There are no wilds.

Bonus features

Mystery artefacts

There are two Mystery Artefacts. The 2x2 and 3x3 reward 3x and 5x multipliers respectively. Each artefact shows matching symbols and rewards a global win multiplier for all winning combinations until the spin ends. 

When more than one artefact lands during the same spin, the multipliers are added up to a maximum of 10x. 

Free spins

Landing 3 scatters unlocks the Free Spins round which rewards 10 Free Spins. Each extra scatter landed exceeding 3 scatters rewards you with an extra 5 Free Spins up to 30 Free Spins. 

Each scatter landed after the feature unlocks rewards you with 1, 2, 3, 4, 5 or 10 Free Spins and increases the win multiplier by a similar value. 

The win multiplier does not reset during the Free Spins round. 

Feature buy

You can skip the hassle of the base game and head right to the Free Spins round using Feature Buy. You must place 150x the bet to unlock Free Spins which you will play at an RTP of 95.87%.

Verdict

Doom’s Digging Machine adds to the portfolio of mining slots. Other familiar slots include Dead Canary, Fire in the Hole 2 and Gold Digger. 

However, Doom’s Digging Machine brings the same theme of low/medium volatility. Additionally, it adds bonus features such as the Mystery Artefact and global win multiplier. 

Finally, its cartoony and retro appearance add to the attractiveness of the slot.
