Crazy Digginz

Pulse 8 Studios sends players underground with Crazy Digginz, a mining-themed video slot built on a 5-reel, 3-row grid with 20 fixed paylines. Stakes run from 0.20 to 20 per spin, Crazy Digginz plays out on a high-volatility math model, and the hit frequency lands at 26.45%. Four RTP configurations circulate depending on the market: 96.02%, 94.14%, 92.10%, and 86.79%.

Card royals from 10 through A form the low-value tier, paying 3x to 5x for five of a kind, while pickaxes, hammers, and coloured gems occupy the higher rungs, worth 8x to 40x the stake for a full line of five. A standard wild lands only on reels 2 through 4 and substitutes for every symbol except the scatter and the three Special Wilds.

Those Special Wilds - Allmine, Flint, and Morpho - each carry out a different job when they land on reels 2-4. Allmine gathers up any multiplier value sitting on the high-paying symbols across the grid and attaches the combined total to itself. Flint scatters multiplier values at random across every symbol bar the scatter. Morpho reaches into the medium- and low-paying tier and bumps a couple of symbols up into random high-paying ones. Only one of each can appear per spin, and all three substitute for anything except the scatter.

A separate random trigger called Crazy Mode can fire in either the base game or the free spins, and while it's running the Special Wilds work harder: Allmine doubles the multiplier value it collects, Flint hands out 8x to 14x multipliers instead of its usual smaller range, and Morpho upgrades two symbol types at once rather than one.

Three, four, or five scatter symbols award 12 free spins, and which Special Wilds are active during the round depends on how many scatters triggered it - three unlocks Allmine alone, four brings in Flint as well, and five arms all three at once. Landing three scatters during the free spins retriggers the round, and the wilds awarded at the start stay in place on reels 2-4 for the rest of the feature.

Where local rules permit it, a Win Booster doubles the base stake in exchange for a better chance of Special Wilds, scatters, or high-paying symbols turning up, and a separate buy option sends players straight into the free spins for 79x, 299x, or 1,999x the stake depending on whether three, four, or five scatters are purchased. Crazy Digginz carries a maximum win of 68,000x the stake and was released by Pulse 8 Studios in February 2023.
