Crazy Digginz – It’s all Mine! Slot Review
Three framed miner portraits hang on the rock wall of a lamp-lit mine shaft, each one wired to the reels like a switch. Crazy Digginz – It’s all Mine! makes a quiet bet that most slots don’t: it puts almost everything interesting in the hands of its characters and leaves the paytable to fend for itself. When none of the three miners shows up, this is a plain 20-line game with modest line pays. When one does, the whole board changes shape under it. A wide-eyed yellow bird on a stick watches it all happen, and he’s the only thing down here with no job.
Pulse 8 have built the slot around those three miners, and it runs on a 5×3 grid with 20 paylines, 96% RTP and very high volatility, with bets from 0.20 to 20.00. Hit frequency sits at 26.45%, so this isn’t a game that pays its way spin by spin. It’s the miners you come down the shaft for.
Base Game & Features
The base game is a 20-line affair across five reels and three rows. Wins pay left to right on adjacent reels, and only the highest combination on each line counts. Standard wilds appear on reels 2, 3 and 4, substituting for everything except the bonus symbols, and they don’t carry a payout of their own.
The three miners on the wall are the special wilds, and each does a different job when it lands. All of them appear on reels 2, 3 and 4, all substitute for everything but the bonus symbol, and none pays on its own. What separates them is what they do to the other symbols around them.
The Three Special Wilds
ALLMINE, the collector, hoovers up value. It collects a x1 multiplier from every high symbol without a multiplier attached, gathers all the win multipliers sitting on high symbols, then adds up the high symbols it has collected and applies that sum as a multiplier to itself. One ALLMINE on a busy set of reels can carry a serious number.
FLINT, the spreader, hands multipliers out instead. It randomly distributes multipliers to all symbols except the bonus symbols, so a single FLINT landing can leave half the win lines carrying boosted values.
MORPHO, the upgrader, takes the other route: it randomly upgrades medium or low symbols into random high symbols, lifting the quality of the reels rather than their multipliers. Where ALLMINE and FLINT make wins bigger, MORPHO makes them more likely to be worth having.
On top of the three wilds, Crazy Mode can trigger at random in the base game and in free spins, and when it does the special wild rewards are increased.
Symbols and Pays
The paytable splits into crystals, pickaxes and royals, with the Red Crystal leading it. Values are multiples of the line stake:
- Red Crystal: 2.5x for three, 4x for four, 20x for five
- Green Crystal: 2x for three, 3x for four, 15x for five
- Blue Crystal: 1.5x for three, 2.5x for four, 10x for five
- Pickaxe (coloured): 1x for three, 2x for four, 5x for five
- Pickaxe (plain): 1x for three, 2x for four, 4x for five
- A: 0.5x for three, 1.25x for four, 2.5x for five
- K and Q: 0.5x for three, 1x for four, 2x for five
- J and 10: 0.25x for three, 0.75x for four, 1.5x for five
High symbols are the three crystals, the pickaxes and the royal letters below them. The crystal tier is where the real line-pay value sits, and it’s also the tier the special wilds interact with, which is no coincidence.
Crazy Digginz – It’s all Mine! Free Spins & Bonus Features
The bonus symbol is a scatter, and it’s active on all five reels in the base game. Land three, four or five of them and the free spins round begins, with the number of spins awarded at random, up to 12. What matters more than the spin count is which of the miners joins you:
- 3 bonus symbols unlock ALLMINE
- 4 bonus symbols unlock ALLMINE and FLINT
- 5 bonus symbols unlock ALLMINE, FLINT and MORPHO
The entry route decides how much of the game you actually get to play, which makes the difference between three scatters and five much bigger than a few extra spins. Each unlocked miner works the reels for the whole round, not for a single appearance.
During free spins the special wilds don’t stay put. They jump between reels 2, 3 and 4, so a wild that misses on one spin can still be in position when the reels settle on the next. Bonus symbols stay active too, but only on reels 1, 3 and 5. Land three more of them and the round retriggers, activating any special wild features that weren’t yet unlocked.
All bets in the round are the same as the triggering spin.
Buy Bonus
The Buy Bonus is available in the base game and triggers the free spins round directly. It’s played at the current bet, and it isn’t available above a certain bet threshold, so the option disappears as stakes climb.
Win Booster
The Win Booster is a permanent toggle rather than a purchase. Activating it doubles the total bet and increases the chance of landing special wilds, bonus symbols and high symbols in the base game. It doesn’t touch line pays, so what you’re buying with that extra stake is frequency, not size. It stacks with everything else the base game already does, including random Crazy Mode triggers.
Our Honest Verdict
Overall Rating: 7.3/10
Most of your time down this shaft is spent waiting. You dig through spin after spin of plain 20-line play, and then one of the three miners lands and suddenly the board is worth looking at. That’s the whole reason to be here: no other game hands this much of its personality to its characters.
The unlock ladder is the best thing about it. Three, four or five scatters don’t just award more spins, they hand you a progressively richer game, and the jumping wilds give the top tier a rhythm nothing in the base game can touch.
The worst thing is the empty stretch in between. A 26.45% hit rate and very high volatility mean the miners stay in their frames for long spells, and the line pays won’t carry a session on their own. This is one for players who like character-driven chaos and have the patience to wait out the quiet. Anyone after steady wins will find the shaft colder than the portraits suggest.
