How Gold Mine Stacks 2 plays
Playing cards pay the smaller prizes and gemstones the larger ones, with the gold nugget wild substituting for the paying symbols. Wilds can land in stacks, and a stack that covers a whole reel triggers Wild Stack Respins.
In that feature the full wild reel locks in place while the other reels respin for free. Every new full-reel stack locks as well and keeps the respins going, and if wilds end up covering all five reels the game pays 400x the stake.
The Gold Mine Stacks Bonus
Three or more gold coin bonus symbols start the bonus with a randomiser spin, which can upgrade one coin prize by up to 20x. If the randomiser shows the safe, every prize is upgraded instead. The coins then stick, and the respins run on a three-lives tally that resets whenever a new coin lands.
Filling a reel with coins lifts every prize by one level, and the ladder has 16 levels. Triggering with four or five coins also awards one or two Super Lives. Reaching level 16 pays the 50,000x top prize and ends the round.
