About Danger! High Voltage

Released on September 21, 2017, Danger! High Voltage is a cult BTG slot inspired by the song 'Danger! High Voltage' by the band Electric Six. RTP 95.67% (below BTG's average of 96.20%), high volatility, max 15,580x. Format 6x4 / 40 fixed paylines (vintage compared to modern Megaways). The signature mechanic: two distinct Free Spins modes to choose from before the bonus: Gates of Hell Free Spins: 7 spins with Heart-Sticky Wilds (heart-shaped wilds that stay on the grid until the bonus ends). Progressive wild build-up means potential for big wins. High Voltage Free Spins: 12 spins with Doubled Wilds (every wild doubles the wins) plus multipliers. More spins, but no sticky feature. The 15,580x max is mainly reached via Gates of Hell with a saturated wild grid, or High Voltage with stacked multipliers. No Bonus Buy available.
