An underground mining adventure
The action unfolds far below ground, where a mighty digging machine bores through rock in pursuit of glittering ore and hidden treasure. BGaming leans into a warm, cartoon-tinged industrial style, so the setting feels adventurous rather than gritty. Gold nuggets, cut gems and mining gear populate the reels, reinforcing the excavation fantasy on every spin.
Features and how they work
The grid runs 5 reels by 3 rows across 10 fixed paylines. Landing three Golden Shovel Scatters awards 10 free spins with unlimited retriggers, and the Shovel also substitutes for regular symbols to complete wins. As the free spins begin, one standard symbol is drawn at random to become the Expanding symbol: it stretches to cover its entire reel and pays on non-adjacent positions. Two staking tools round it out - Buy Bonus purchases direct entry to the round, while Chance x2 raises the stake to lift the natural trigger rate.
RTP, volatility and top prize
BGaming lists a default theoretical RTP of 94.94%, a long-run average rather than a promise for any single session; the figure can differ across certified or operator-selected configurations, so the value displayed in the game client is always the authoritative one. Volatility sits at the very high end, meaning rewards are rarer but potentially large. The maximum win reaches up to 7,500x the total bet.
Why add it to your lobby
For operators, Dig Dig Digger delivers the familiar book-style expanding mechanic in a fresh, non-Egyptian mining wrapper, adding welcome variety to a crowded portfolio. Its very high volatility and 7,500x ceiling create strong big-win storytelling for promotions, while the Buy Bonus caters to feature-hunting audiences. The title is HTML5-native for smooth mobile play and supports both crypto and fiat balances for flexible integration.
