Dig Dig Digger - official features and review
Dig Dig Digger builds an Egyptian excavation around the book-style expanding-symbol mechanic. The Golden Shovel has a dual role, while the bonus can collect several different expanding symbols. Understanding the expansion thresholds matters more than the size of the animated gold piles.

The shovel's two jobs
Released by BGaming on July 16, 2021, Dig Dig Digger uses a five-reel, three-row grid with 10 paylines. The current official profile lists 94.94% RTP, very high volatility and a maximum multiplier of 7,500x. Those figures describe the published product profile; they do not establish the configuration of every available build or predict an individual bonus result.
Ordinary line wins run from left to right across consecutive reels. If several lines win together their awards are added, with the highest eligible combination paying on each individual line. The Golden Shovel Scatter also acts as a Wild, substituting for symbols in a line. Its Scatter role is separate: three or more in one spin trigger 10 free spins.
The difference is useful when examining an apparently unremarkable result. A Shovel can help a line without launching the bonus, while a sufficient Scatter count can start the feature without an ordinary line connection. Scatter payments use the total bet, whereas regular line awards use the bet per line. Read the paytable on the same basis as the award being evaluated.
Expansions do not need adjacent reels
At the start of free spins a regular symbol, excluding Scatter, is randomly selected as a special expanding symbol. If enough instances land on different reels, they expand to cover their reel positions. Unlike ordinary line wins, these special symbols do not need to be on adjacent reels for the additional award. That difference is the central bonus rule, not a general permission for all ordinary symbols to pay anywhere.
The directly linked June 2, 2021 rules specify two thresholds. High and medium symbols, identified as Digger, Vase, Key and Scarab, require at least two different reels. Low symbols A, K, Q, J and 10 require at least three. Therefore the required count depends on which symbol has been selected; a two-reel low-symbol appearance should not be evaluated using the premium-symbol threshold.
Three or more Scatters during free spins can retrigger the feature, with no finite retrigger limit stated. The rules also allow the special expanding symbol to be selected up to nine times during the bonus through retriggers, and previously selected special symbols remain active until free spins end. The accumulation creates the feature's interest, but neither another selection nor a retrigger is guaranteed.
Purchasing access and risking a settled win
Buy Bonus, where available, offers 10 free spins with a choice of one to nine expanding symbols. The displayed price depends on the selected option and bet. Chance x2 is a different paid setting that raises the stake to improve bonus-entry chances. The two purchase features cannot be active together. The linked rules leave separate RTP fields for the nine purchase levels and Chance x2 unfilled, so 94.94% should not be assigned to all those modes without live configuration evidence.
A main-game win can also make Gamble available. Guessing the card colour correctly doubles the risked win; guessing the suit correctly pays four times that amount. A wrong guess loses the amount put at risk. Collecting avoids that additional wager. This optional round is not a method for repairing a losing base-game session.
Dig Dig Digger is strongest when the distinction between regular lines and special expansion awards is kept clear. Its bonus offers more development than a single-symbol book round, at the cost of very high volatility and potentially expensive purchase choices. Compare the active paytable and displayed prices, set a budget and treat promotional win screens as illustrations. The verified rules support no strategy that makes selected symbols or Golden Shovels arrive on demand.
