Bonus Rounds in 12 Bolts of Thunder
There are a number of bonus features in 12 Bolts of Thunder to look out for:
Wilds
There is a wild symbol in the slot that is represented by a pair of wings in a W shape on a shield. It works similarly to most wilds and can replace all symbols to create winning combinations apart from the bonus and hammer symbols.
Hammer Win Feature
If you manage to land Thor's Hammer symbols on the middle reels during the base game, there is an improved reward.
The payout increases with the number of Hammers visible, starting at 2x for four Hammers and going up to 1,000x the stake for a full set of 12 Hammers.
Free Spins
To trigger the free spins bonus round in the game, you'll need to land three, four, or five scatter symbols anywhere on the reels - and you'll be given six, nine, or twelve free spins, respectively.
During the free spins bonus round, the Hammer Win feature is there to add even more winning potential. Every time you land a win with a Hammer symbol, it will take you an extra step up the Hammer prize ladder to bigger and better levels. If you manage to get to 12 Hammers at the top level, you'll receive the maximum win of up to 30,000x your stake. What's more, each Hammer Win during free spins will also award you three extra free spins.
