About this Slot
Heimdall Hammer is a mythology-themed slot by Golos Games with an RTP of 96.7%, high volatility and a maximum win of 25,000x.
Two hammer types land as special symbols with multipliers. The Green Hammer lands with a multiplier, transforms the reel it occupies into a Wild, and converts symbols below it into Wilds as well. During the bonus round, the Green Hammer's multiplier grows multiplicatively and remains sticky throughout the feature. The Blue Hammer also lands with a multiplier, transforms its reel and symbols below into Wilds, and then awards a respin. The Blue Hammer's multiplier grows additively as it drops. Only one hammer type appears per spin.
Multiplier Boosters land as x2, x5 and x10 symbols, increasing the value of all hammers currently on the board. These boosters remain active during the Free Spins round.
The Bonus Game triggers when three or more Bonus symbols land. It awards Free Spins and uses a separate reel strip. Green and Blue Hammers stay sticky throughout the feature. Multiplier Boosters continue to function during Free Spins, and additional Bonus symbols can retrigger extra spins.
Four bonus buy options are available. Bonus Boost costs 5x the bet, Super Spins costs 100x the bet, Bonus Game costs 300x the bet, and DEGEN Spins costs 500x the bet.
