We will be direct about this one. Dig Dig Digger has the lowest published return of any BGaming game covered on this site, and it is classified very high volatility. That is the least favourable combination of the two numbers that matter, and it is worth being clear about before anything else.
The combination
94.94% return. Very high volatility.
Low return means you lose faster on average. High volatility means the outcome of any given session is wildly uncertain. Together they mean long empty stretches at a worse price than the alternatives.
Compare within the same studio and the same mechanic:
| Dig Dig Digger | Book of Cats | |
|---|---|---|
| RTP | 94.94% | 96.99% |
| Volatility | Very high | Very high |
| Mechanic | Expanding-symbol free spins | Expanding-symbol free spins |
| Lines | 10 | 10 |
| Max win | 7,500x | 8,202x |
Same studio, same format, same line count, similar ceiling. Two full percentage points of difference in return. On $1,000 of turnover that is about $20 of expected difference, and there is no compensating advantage in the Dig Dig Digger column.
If the expanding-symbol format is what you want, Book of Cats is the better-priced way to get it.
How it plays
Three scatters trigger ten free spins, and the scatter also acts as a wild. As in any book-format game, a random symbol is selected to expand for the duration of the round, and the round retriggers.
The mining theme is executed well and the game has a following. Neither of those things changes the maths.
What the ceiling means here
7,500x, reached through a high-value expanding symbol across a retriggered round. As with all games of this shape, the ceiling is a computed maximum rather than a target — the distance between a typical feature and the maximum is several orders of magnitude.
The buy and chance options
Available where permitted. On a game returning 94.94%, a bonus buy is the least favourable version of an already unfavourable transaction: you are paying a fixed price to access a feature whose expected return is below 95%. Nothing about buying improves that number.
Who it suits
Honestly, few people, on the numbers alone. If you specifically like this game's theme and presentation and you are playing for entertainment with money you have already written off, that is a legitimate reason and no table of percentages overrides it.
But if you arrived here comparing options within BGaming's catalogue, Book of Cats offers the same mechanic at a materially better price, and Aztec Magic Megaways offers a higher ceiling at a better return again.
