Space Digger is powered by Playtech and comes with 5 reels and 20 paylines. Playable on all devices from 10p to £500 per spin, you head to outer space where you dig for gems galore. It comes with stacked wilds that shift 1 reel until you get a winner. The free spins feature begins with 1 stacked wild with other wilds nudging to give you more wild reels.
Set in outer space, you’ll see the burning sun and gems in the backdrop – it looks rather nice. Fast-paced, you’ll see 4 different-coloured gems (orange, blue, purple and red) as well as 3 different types of diggers. All 3 of them will reward you with 0.5, 1.5 or 4 times your stake for 3, 4 or 5 across a payline. There’s the Space Digger logo which is the most rewarding – 2, 3, 4 or 5 will give you 0.3, 1.2, 3.5 or 10 times your stake.
Then you have the digger wild which appear stacked – 2, 3, 4 or 5 will give you 0.5, 2.5, 5 or 12.5 times your stake. It substitutes for all symbols bar the bonus scatter. When the digger wild appears fully on any reel, you will trigger the Wild Digger feature. When part of a win, it shifts 1 reel to the right – the digger remains on that reel if not part of a winning combination. With each win, it shifts right until it shifts off the reels.
Space Digger also comes with a Hidden Gems Free Games feature – this is played when 3 bonus scatters appear simultaneously on the 3 middle reels (reels 2, 3 and 4). With 8 free spins awarded, you will begin with a fully visible digger wild on reel 1 – this means the Wild Digger feature is automatically in play. Furthermore, any stacked wilds from the base game appear in the free spins.
Any free spin with a win from the stacked wild will make it shift 1 reel right. Furthermore, wilds will nudge up and down to fully take over their reel – thus triggering the Wild Digger feature. This could result in a screen full of digger wilds – if you achieve this, you’ll win 250 times your total stake (on each free spin). If you finish the free spins with stacked digger wilds on the reels, they will appear in the base game.
I really like Space Digger – it looks great and has shifting wild reels in both the base game and Hidden Gems Free Games feature. The disappointing bit is that a screen full of wilds will only result in a 250 times stake payout – variance wise, it’s therefore low.
This slot would have been a real favourite if the value of the symbols were 5 or 10 times higher. For a more potentially rewarding adventure into outer space, Big Time Gaming’s Opal Fruits is recommended as you can win up to 36,000 times your stake on each spin/free spin.
