About this Slot
Heimdall's Watch is a mythology and fantasy-themed slot from Blooball Gaming with an RTP of 96%, high volatility and a maximum win of 50,000x. The game features a 5x5 grid with 19 paylines.
Heimdall's Strike is a base game feature that converts 2-4 randomly selected symbols into wilds on any spin, except scatters. This mechanic can land on any base spin without restriction.
Scatters trigger one of four free spins modes. Landing 4 scatters activates Thor Bonus, which awards 10 free spins. During this mode, Thor expands a full-reel wild on each spin. Chain Lightning can create extra wilds with double value during Thor Bonus spins.
Landing 5 scatters triggers Loki Bonus, also awarding 10 free spins. During this mode, Loki walks left one reel per spin, and the Loki multiplier increases as the bonus progresses.
Landing 5 scatters plus a Ragnarök scatter activates the Ragnarök mode, which grants 10 free spins and combines the mechanics of Heimdall's Strike, Thor's expanding wilds and Loki's walking multiplier. Surtr removes certain symbols before specific spins within this mode.
The game offers six buy options to access bonus features directly. The Ante costs 3x bet, Super Ante costs 6x bet, Heimdall Bonus costs 200x bet, God Spin costs 250x bet, Thor Bonus costs 300x bet, and Mystery Bonus costs 500x bet.
