Doom’s Digging Machine Slot Conclusion

“Archaeology holds all the keys to understanding who we are and where we come from.” Octoplay has created a high-tempo gaming experience, providing a fun archaeology theme with an unusual sci-fi twist. This is not the first time we’ve seen this humorous mix of themes from Octoplay, with Crop of the Dead being a recent example, mixing zombies with farm life. We have a soft spot for great background music, and this game provides a screeching tune, which does not suit everybody, but we liked it, as it was perfect for this quirky theme.

Regarding the stats, this low-volatility game offers a max win of 5000X the bet and a below-average RTP of 95.70%, which is not very exciting numbers but should attract players looking for more frequent but smaller hits. The scatter pays mechanic is the highlight of this game, and we’ve previously seen this eventful feature in games like Crop of the Dead, a game that offers the same formula of Cascade feature, Multipliers and Free Spins. The main difference between the games is the significantly higher win potential of Crop of the Dead, offering a max win of 10,000X. While playing Doom’s Digging Machine, we made some great wins thanks to the Mystery Artefact, carrying multiplier values up to 5X, which is collected in the Global Multiplier and applied to all wins. This generous multiplier is persistent during the Bonus Game and was the reason behind some decent wins, especially when we managed to retrigger additional Free Spins.

To summarise, this game offers a playful vibe that should attract players looking for a low-volatility gaming experience. We appreciated the scatter pays mechanic in combination with the Global Multiplier, a formula for success. With that said, it feels like we’ve seen this game before and wish the provider would shock us with some new innovative gameplay, but if you like previous releases from Octoplay, such as Barhalla and Flaming Frenzy, this game is worth a peek.

Doom’s Digging Machine is a slot with a humorous vibe, offering a multiplier value of up to 100X.
