Official Belatra materials describe Crystals Digger as a 6×5 cascading slot with a Pay Anywhere system, while some listings also label the format as cluster pays. The supplied data lists 90.39% RTP and a 0.20 to 100.00 bet range, so confirm the live paytable in the casino lobby before playing for real money.
How Crystals Digger works
Crystals Digger runs on a 6×5 grid and uses a Pay Anywhere system instead of fixed paylines. Wins are formed by matching symbol groups anywhere on the screen, and each successful hit clears away before new symbols drop into place through cascades.
That means the base game is less about line tracking and more about whether one hit can roll into the next. The mining theme suits that structure well, because the board feels like it is constantly being dug open for another layer of gems, multipliers, or bonus progress.
The main feature trigger comes from scatter symbols. Four or more scatters award 10 free spins, extra scatters can extend the round up to 300 total games, and reel multipliers can sharply increase the value of a good sequence once the bonus starts.
Main features
- 6×5 grid with Pay Anywhere wins and cascading symbol refills
- Four or more scatters trigger 10 free spins with retriggers
- Free spins use win multipliers to lift stronger cascades
- Craft Bonus gives direct access to the main feature route
- Wheel of Fortune jackpots add a separate upside layer
Who will enjoy this slot
- Players who prefer cascading grid play over fixed-payline slots
- Belatra fans looking for multipliers, free spins, and jackpot hooks
- Users who like feature chasing more than steady base-game rhythm
- Sessions built for medium-high variance rather than low-risk grinding
Crystals Digger combines medium-high volatility with a listed RTP of 90.39%, so bankroll swings can feel sharp when cascades and bonus entries do not arrive. Keep stake size controlled and use the tools in our Responsible Gambling guide.
Bonus structure and payout profile
The payout profile is built around chained movement rather than static payline math. A base hit can remove symbols, refill the grid, and set up another win immediately, so even ordinary spins have some carry-over potential when the symbol spread lands well.
Free spins are the main bonus engine. They begin with 10 rounds from four or more scatters, retrigger through additional scatters, and apply win multipliers that can turn a simple cascade sequence into the best stretch of the session. The feature cap of 300 free games shows where the slot saves most of its upside.
Outside free spins, Crystals Digger also layers in a jackpot Wheel of Fortune and bonus buy access. Even with those extras, the listed max win of 2000x keeps the ceiling below more aggressive grid slots, so the game feels more like a feature-led medium-high variance title than an extreme top-win chase.
Crystals Digger compared with similar Belatra slots
| Slot | Provider | Format | RTP | Volatility | Best fit |
| Crystals Digger | Belatra Games | 6×5, Pay Anywhere | 90.39% | Medium-high | Players who want cascades, multipliers, and buy-bonus access |
| Big Bang | Belatra Games | 8×8, Cluster Pays | 96.11% | High | Players who want a larger grid and a stronger long-run RTP |
| Big Wild Buffalo | Belatra Games | 5×3, 25 paylines | 91.51% | Medium-high | Players who prefer classic reel structure with Hold and Win |
Compared with those games, Crystals Digger is the more compact mining-grid option. It keeps the feature set busy with cascades, multipliers, retriggerable free spins, jackpots, and bonus buy access, but its 2000x ceiling makes it less of a pure max-win hunt than some larger-format alternatives.
