The game has a very stylish design, while the gameplay is fast-paced and entertaining. There is a wide range of coin sizes on offer, making the game accessible to all players, and the overall low volatility helps to create high levels of engagement (the RTP is 95.35%). Packed with a range of special features, it is easy to see Space Digger becoming one of the highlights in the Playtech slots portfolio.

How to play

Space Digger is a 5 reel, 20 payline video slot with all wins paying left to right (except for latter wins, which pay anywhere on the reels). All wins are multiples of the total bet, and bets range in size from £0.10 to £500.

  • Wild Digger symbol substitutes for all other symbols except the scatter
  • Wild symbol can nudge and expand to fill the entire reel
  • Expanded wild symbol triggers the Wild Digger feature
  • 5x Wild Digger symbols = 12.5x total bet (up to £6,250)
  • Space Digger logo symbol is the scatter
  • Hitting 3x scatter symbols on reels 2, 3 and 4 triggers the Hidden Gems free spin feature
  • 5x scatter symbols = 10x total bet (up to £5,000)
  • 5x digger drill symbols = 4x total bet (up to £2,000)


The maximum possible jackpot payout on Space Digger is £125,000 when betting the maximum. This can be won during the Hidden Gems Free Spins bonus when stacked digger wilds appear on all 5 reels and all 20 paylines.

The biggest potential win during base play is £6,250 for hitting 5x digger wild symbols on a payline when betting the maximum.

Special features

Wild Digger Feature

When a wild symbol expands to fill an entire reel, the Wild Digger feature is triggered. Expanded wild symbols are locked in place, and move one reel to the right on each subsequent spin until forming part of a winning combination. The Wild Digger feature is in play both during base play and the Hidden Gems Free Spin feature.

Hidden Gems Free Spin Feature

The Hidden Gems Free Spin feature is triggered by hitting 3x scatter symbols on reels 2, 3 and 4. Triggering the feature awards 8 free spins, which begin with a wild digger symbol on reel 1 so that the Wild Digger feature is automatically in play, while any stacked wilds that were on the reels when the free spins were triggered remain in play.

During the free spin feature, wild symbols can nudge to create stacked wilds, and stacked wilds that form part of a winning combination remain in play for the next spin. Any stacked wilds remaining on the reels at the conclusion of the free spins bonus carry over back into base play.

Graphics and Sounds

Set in a futuristic world where planets in outer space have been colonised and are being mined for precious gems, Space Diggers has echoes of a variety of different sources, such as the NetEnt slot Starburst, characters from Transformers, and even old-school arcade games like Space Invaders.

The design is stylish featuring a stark lunar landscape, with a sun and moons in the background. The sound track and sound effects are suitably eerie and help to create a sense of suspense and excitement throughout the game.


It is easy to see why this new release from Playtech might become one of the most exciting new slot games of recent times. There is a good deal of variety in the gameplay, with the wild symbols, in particular, playing a prominent role. Expanding wilds that can move across the reels is a feature that is not unique, but at the same time it doesn’t appear all that often, and so this aspect of the game is sure to draw players’ attention. The free spins round is relatively straightforward, but the way in which the stacked wilds carry over from base play into the free spins round is a good innovation. The only mildly negative reaction that the game has received is that the maximum potential jackpot of 250x the total bet is on the low side, and is not really comparable with other similar games.

This quibble aside, Space Diggers looks set to be a smash hit, and so why not check it out for yourself at our recommended casinos.
