Standard play in the Double Digger slot takes place on 5 reels, 3 rows and 243 ways to win. Create winners by landing 3, 4 or 5 matching symbols an/or wilds on adjacent reels, starting from the leftmost reel. You can take the number of ways to win up to 1,944 by activating the Extra Bet.

Bet levels here range from between 10p and £340 per spin in standard play mode. This increases to 25p and £500 per spin with Extra Bet active and the extra symbol positions added. Use the Coins icon to adjust your stake. The maximum bet will be reduced at most slots sites though so expect it to be around the £50-£100 mark.

Theme: dig deep for dazzling diamonds

Theme: Mining

High-Value Symbol: Miner

Compatibility: Mobile, Tablet, Desktop

double-digger-slot-base-game

With a mining theme, the design in the Double Digger slot is quite simply put together but works well all the same. Mountains, greenery and a railroad leading into the mine for the backdrop to the reels. The soundtrack bounces along nicely, punctuated by the clanging of axes and shovels. It works well.

On those reels, you’ll find 6 lower value gemstones, a pickaxe, dynamite, a torch, a miner’s helmet, and a wheelbarrow full of gold. The bearded miner is the most rewarding standard symbol. He pays 1, 2 or 5 x your total bet if you land 3, 4 or 5 in combination.

The Gold Wild symbol substitutes for all the standard symbols. Unusually, it can also trigger a feature. I’ll look at this in detail below. Other symbols to keep an eye out for are diamonds. These come with cash and jackpot values attached. Here’s what the symbols pay:

  • Purple Gemstone: 3, 4 or 5 = 0.2, 0.5 or 1 x bet
  • Green Gemstone: 3, 4 or 5 = 0.2, 0.5 or 1 x bet
  • Green Club Gemstone: 3, 4 or 5 = 0.2, 0.5 or 1 x bet
  • Red Diamond Gemstone: 3, 4 or 5 = 0.2, 0.5 or 1 x bet
  • Pink Heart Gemstone: 3, 4 or 5 = 0.2, 0.5 or 1 x bet
  • Purple Spade Gemstone: 3, 4 or 5 = 0.2, 0.5 or 1 x bet
  • Pickaxe: 3, 4 or 5 = 0.4, 0.8 or 2 x bet
  • Dynamite: 3, 4 or 5 = 0.4, 0.8 or 2 x bet
  • Torch: 3, 4 or 5 = 0.4, 0.8 or 2 x bet
  • Miner’s Helmet: 3, 4 or 5 = 0.4, 0.8 or 2 x bet
  • Wheelbarrow: 3, 4 or 5 = 0.5, 1 or 3 x bet
  • Miner: 3, 4 or 5 = 1, 2 or 5 x bet
  • Wild: Substitutes for all standard symbols
  • Diamond: contains cash or jackpot values
  • +5: Free spins trigger during Double Wild feature
  • Multiplier: Available in free spins only

Double Digger Mobile

double-digger-mobile-slot

You can go digging for jackpots on smartphones and tablets as well as on desktop and laptop computers. The Double Digger mobile version has been fully optimised for play on iOS and Android handsets.

Double Digger Bonus Features

The features, and the way they are triggered, are a little unusual in Double Digger. It’s wilds rather than scatters that can help activate the bonus features. They can also deliver special bonus and jackpot prizes.

Extra bet feature

The Double Digger slot comes with an optional Extra Bet feature. If enabled, you will extend reels 3, 4 and 5 by 3 rows which increases the number of ways to win from 243 to 1,944. This increases your chances of landing diamonds and Free Games symbols. Costing 2.5 x your total bet, payouts and fixed jackpots remain the same as it playing without the Extra Bet feature.

Double Wild feature

The Double Wild feature triggers when you land Wilds on both reels 1 and 2 on the same spin. It can deliver a variety of outcomes.

You’ll notice that diamonds on reels 3, 4 and 5 come with cash values attached. In standard play, these are worth 1 to 15 x your total bet. With the Extra Bet feature live, the values range from 0.4 to 6 x your total bet.

When the Double Wild feature is active, the amounts attached to the diamonds are awarded as prizes as long as they appear adjacent on reels 3, 4 or 5. For example, Wilds on reels 1 and 2 plus diamonds on reels 3 and 4 would pay all the values attached to the diamonds on reels 3 and 4. If you land 2 wilds on reels 1 and 2 and diamonds on reels 3 and 5, only the reel 3 amounts are awarded.

As well as cash values, diamonds can also come with 4 possible jackpots attached. Again, these are awarded if they’re on an adjacent reel when the Double Wild feature has been activated. Here’s what on offer when Extra Bet is on or off:

Free Games feature

double-digger-slot-free-games-feature

Like the diamond prize and jackpots, the Free Games feature is triggered via the Double Wild feature. If any free games symbols make up a winning combination with the wilds, they award the same number of free spins.

The free games symbols appearing on reels 3, 4 and 5 contain the following amounts +3, +4, +5, +7 and +10. For example, wilds on reels 1 and 2 in combinations with a +3 symbol on reel 3 and a +5 symbol on reel 4 will get you 8 free spins. The free spins play out with 1,944 ways to win. Also, the Double Wild feature can trigger during the free spins, just like in the base game.

Joining the action are Multiplier symbols which can appear on reel 5. The multiplier is triggered when the Double Wild is active and you land free games and/or diamond symbols on reels 3 and 4. The multiplier is then applied to the value of any active diamond prizes.

Retriggers are possible too. Land the Double Wild and then free games symbols to add those extra free spins to your total. There’s no limit to how many times you can retrigger them.

Double Digger Verdict: wilds key to excavating prizes

3.7/5
Based on our expert’s review. Reviewed by
Double Digger Slot

Double Digger is a mining-themed slot where wilds excavate diamond prizes, jackpots and free spins. With up to 1,944 ways to win, this explosive game offers 5,428.9 x bet max wins.

Pros
  • 5,428.9 x bet max wins
  • Up to 1,944 ways to win
  • Unique gameplay
Cons
  • Below average RTP (95.89%)
  • Not many bonus features

The gameplay in the Double Digger slot is a little unusual and takes a bit of getting used to. I recommend taking it for a spin in free play mode if possible, just to get accustomed to the Double Wild feature and what it can potentially deliver.

Basically, you need to land Wilds on reels 1 and 2 in order to excavate all diamond prizes on the other reels. In the Free Games feature, you’ll play with 1,944 ways to win which helps you land accumulative Multiplier symbols and scatters for more free spins.

When you have got your eye in, there’s some decent stuff on offer here courtesy of the diamond prizes, free spins and multipliers. Visually, it’s rather appealing too. With 5,428.9 x bet max wins, I recommend trying the Extra Bet feature.

Whilst it may cost 2.5 times higher per spin, you play with 1,944 ways to win in the base game. This will lead to more Free Games and diamond symbols. Also, triggering a bonus feature will be 1 in 84 spins on average compared to 1 in 132 spins without it. Winning 1,000 x your total bet or higher will take approximately 1.56 million spins. With Extra Bet, it’s 1 in 2.7 million.

In conclusion, the Double Digger slot comes together rather nicely overall, though. The gameplay is different and there’s scope to excavate some decent wins.

With lots of mining-themed slots around, Double Digger has its work cut out. You have Big Time Gaming’s Bonanza Megaways as the standard for starters. The sequel, Bonanza Falls, introduces a Megadozer mechanic. It comes with a 96.51% RTP rate and 93,540 x bet max wins.

Personally, I love Nolimit City’s mining games. Fire in the Hole 2 (4.8/5 rating) and Misery Mining (4.9/5 rating) offers explosive win potential (65,000 x bet and 70,000 x bet max wins respectively) as well as unique mechanics and innovative gameplay.
