If you like either the theme of the game or the developer’s style, there are plenty of options. For Twist Gaming titles, with similar bonus features for example, we recommend Lab of Lunacy or Carp Diem; both slots that our test team happened to love.
If you’re thinking more gold-digging slots, then you’ve got Gemstones Gold, Misery Mining, Crystals Digger, Dynamite Miner, and so forth at Stake. And there are even games called Gold Digger and Gold Digger Megaways carried by other operators, that’s how popular this specific theme is.
