Go mining for treasure on a distant planet in Space Digger. Created by Playtech, it’s a 5 reel, 15 payline video slot where stacked wilds walk across the reels whenever they form part of a winning line. Trigger the feature and you’ll receive 8 free spins which start with a stacked wild on reel 1. Play on your PC, tablet or mobile devices from between 10p and £500 per spin.
With planets and moons in the background, the action here takes place on the rocky surface. The 4 lower value crystal symbols are joined by 3 higher paying pieces of machinery. The top award comes from the Space Digger logo. Land 5 of them on a payline then you’ll pocket an award of 10 times your bet.
The digging machine wild is central to the action here. Land the machine fully stacked and you’ll play the Wild Digger feature – it then turns the whole reel wild. This stacked wild then shifts 1 reel to the right whenever it forms part of a winning combination. If it’s not part of a winner, it stays in position until it does. The stacked wilds keep shifting until they drop off reel 5.
The main feature is the Hidden Gems Free Games feature – to trigger it, you’ll need to land the Bonus symbol on reels 2, 3 and 4 on the same spin. On offer are 8 free spins. A stacked wild is added on reel 1. This shifts across the reels just like in the base game.
If you had any stacked wilds in play on the triggering spin, then they too are in play during the feature. If any part of a wild digging machine lands in the free spins, it nudges up and down to fill the whole reel. This too then shifts to the right on each subsequent winning free spin. Any stacked wilds that are left when the free spins are over are carried back to the base game.
Space Digger has the feel of a 1950s sci-fi movie. The visuals impress, backed by an electronic backing track which fits the theme nicely. There isn’t a huge range of features but the stacked shifting wilds can deliver plenty of action, especially if you land more than 1 of them during the free spins.
Saying that, it’s low variance with top wins of just 250 times your bet per spin or free spin. If you enjoy the galactic theme, there are better video slots out there – such as the volatile Opal Fruits from Big Time Gaming.
