Dig Dig Digger: a book slot in a hard hat
Dig Dig Digger is BGaming's 2021 spin on the book formula, trading dusty tombs for a mining site full of drills, dynamite and buried treasure. Mechanically it walks a well worn path, five reels, an expanding symbol free spins round and a buy button, but the execution is brisk and the theme lands. The number to know before anything else: the widely circulated build returns around 94.94%, meaningfully below the modern average, and we weigh that heavily in this review.
What kind of slot it is
This is a five reel, three row slot in the classic book layout, its reels stacked with pickaxes, lanterns, gems and the digger himself. Golden shovels do the scatter work that golden books do elsewhere. Sessions play out in the familiar rhythm of the genre: steady line wins, then everything hanging on the free spins round. If the book format is new to you, our slots guide covers the basics, and Play'n GO's Book of Dead is the obvious reference point players will recognise.
The expanding symbol free spins
Land three golden shovels and you receive ten free spins. Before the round begins, one paytable symbol is chosen at random as the special expander: whenever it lands during the round, it stretches to cover its whole reel and pays like a scatter, without needing to sit on adjacent reels. Draw a premium symbol and the round can reach toward the game's advertised 7,500x ceiling; draw a low royal and ten spins can come and go quietly. That lottery inside a lottery is the book genre in miniature. A buy option triggers the round directly for a premium, which our bonus guide suggests treating with care.
RTP and volatility
The commonly listed return is around 94.94%, a full point under the 96% norm, and BGaming ships configurable builds, so the info screen check is essential. Our RTP explainer shows what that point costs over time. BGaming rates the game very high volatility and our sessions agree: base play mostly marks time, the free spins decide everything, and which symbol expands decides the free spins. Our volatility guide explains why that structure produces long droughts and sharp spikes.
How to play Dig Dig Digger
Stake small and plan for a long runway, because the game's value is concentrated in a feature that arrives rarely. We would pass on the bonus buy at this RTP level; paying a premium into below average math compounds the disadvantage. Decide a deposit cap and a walk away point before the first spin, and let the tools on our responsible gambling page hold the line. Chasing a cold book slot is one of the fastest ways to spoil a bankroll. 18+.
Is Dig Dig Digger worth playing?
Strengths: a clean, fast take on a proven format, a likeable theme, a 7,500x advertised ceiling and wide availability in crypto lobbies. Weaknesses: a below average listed return, total dependence on the bonus round and nothing mechanically new. Book fans who already accept the genre's swings will find it comfortable; anyone choosing on value should compare RTP builds first. The studio's wider catalogue is in our BGaming provider review, and our casino reviews list licensed operators that carry it.
