A first glance at Drill That Gold leaves the impression of just one of many standard slots out there. A miner appears on the right, with plenty of gold nuggets behind him. You also see a 5×3 game panel with a wooden plank frame sitting in the centre of everything. The graphics are clear, and reel symbols are amazingly easy to understand. Guitar chords play in the background as you spin, which is nice if you enjoy background music. The slot is also very well animated.
There are ten pay symbols and 20 fixed paylines where the winning combinations land to aid in the drilling action. The ten to ace playing card rank tiles are on the lower side of rewards, paying from 0.8 to 2x your stake. The premium bunch of symbols includes a digger, a diamond, a miner, and a carriage with gold, and these pay anything from 3.2 to 10x your stake. The slot also comes with a TNT wild symbol. This appears on all the reels and substitutes for the regular symbols to create potentially better winning combinations.
Drill Feature
In the Drill Feature, a stack of miners hit and transform into a silver drilling symbol. This drilling symbol expands going upwards and becomes a wild. This can then reveal a cash prize as lucrative as 100x your stake.
Spin Modifiers
These act on non-winning spins, turning them into winning spins valued of at least 10x your bet size. Spin Modifiers may also produce enough bonus symbols to trigger the Gold Spins Bonus Round.
Gold Spins Feature
You can trigger this feature with three, four, or five bonus symbols. You receive six, eight, or ten free spins, respectively. During this round, a new golden drill may also appear. Like the silver drill, the golden drill also expands while guaranteeing cash prizes worth 5x, 10x, 15x, 25x, 50x, 75x, 100x, 200x, 500x, or 1,000x your stake. The miner symbol hits during this bonus round as well. This nudges up or down, revealing a full stack of miners for a chance with another silver or golden drill.
Ante Bet
The Ante Bet Feature comes with a guaranteed golden drill in the base game. However, you’ll incur an extra 25% on your current bet to enjoy this option.
