The rocky surface of a red planet forms the backdrop to the action here. On the reels you’ll see orange, blue, purple and red crystal as well as 3 bits of machinery. The Space Digger logo is the top standard symbol. It pays 0.3, 1.2, 3.5 or 10 times your total stake if you land 2, 3, 4 or 5 across a payline.
The digging machine is the wild. Land this fully stacked to trigger the Wild Digger feature - the stacked wild then shifts 1 reel to the right with each winning spin that follows until it drops off the end of reel 5.
Land the Bonus symbol on reels 2, 3 and 4 on the same spin and you’ll trigger the Hidden Gems Free Games feature - you’ll then receive 8 free spins with a stacked wild added to reel 1. Just like in the base game, if the wild forms part of a winner it shifts 1 reel to the right.
If part of a wild lands during the free spins, it nudges to fill the whole of the reel. It too then walks across the reels towards the right side of the reels. You can land multiple stacked wilds here. If any wilds are visible on your final free spin, they’ll be in position when you return to the base game.
There’s a slightly retro feel to the visuals in Space Digger which are nicely done. It’s backed by an electro-style backing track which is a good fit. The stacked wilds are central to the straightforward gameplay. Get a good number of those in the Hidden Gems Free Games feature and the action can really get moving.
Space Digger is a simple, entertaining game. Despite the good features, you can only win 250 times your stake on each spin or free spin. If you fancy digging, head underground with Cascading Cave (also by Playtech) which offers top payouts of 10,000 times your stake.
