The transparent backgrounds on the reels of the symbols allow players to have a clear view of the mine while they spin. The symbols on the reels of this slot game include a wheelbarrow, a gold nugget, a gold bucket, the miner’s safety lamp and a trolley cart, all of which get animated when in winning combinations.
The jackpot symbol is the troll that offers the highest payout and five of these appearing on an active pay line will award a jackpot payout of 1,000 coins. The gear wheels trigger the free spins, three of which award 5 free spins, four award 10 free spins and five award 20 free spins during which time payouts are tripled. New wins result in the miner, who is the expanding wild, to occupy the entire reel, jumping up and down with joy. The expanding wilds appear on reels 1, 3 and 5 only.
Two bonus games appear on the second screen of this new online slot game, namely the Pick a Crate bonus game and the Dig for Coins bonus round.
Rival Gaming’s Diggin Deep 20 paylines slot game allows players to wager up to 10 coins per line with coin sizes varying from 0.01 credits to 0.25 credits.
