Grab more Gold! is a twenty-line mining slot from 3 Oaks Gaming, using five reels with four rows. Gold nuggets carry money values that the Miner collect symbol gathers when they appear together. Mystery symbols can reveal a fixed prize when a collect symbol is present. During free spins, hooks can bring in a missing Miner and dynamite can supply missing money symbols. Collect symbols also advance a progress meter, adding spins and increasing the multiplier at successive levels. Super Free Spins use larger money-symbol values, rather than changing the game into a separate jackpot table.
