About this Slot
Storm Caller is a Greek mythology slot from Darkbyte with an RTP of 95.5%, medium volatility and a maximum win of 25,000x. The game uses six reels, four rows and 4,096 ways to pay.
Bolt Wilds substitute all paying symbols and apply a multiplier ladder ranging from x1 to x500. When multiple Bolt Wilds land on a single way, their multipliers multiply together. A Charged Wild is created when a bolt strikes an existing Bolt Wild, applying a multiplier between x2 and x1000 to the wild beneath it.
Cloud Strike fires a bolt down a reel column after the spin ends. This bolt may convert one cell in the struck column into a mystery symbol via Mystery Rain.
Storm Arc lands on any reel and multiplies the entire spin value if a win is formed. During free spins, Storm Arc adds to the Storm Meter instead of multiplying the spin.
Thunder Scatter controls the free spins tier and can land on reels or trigger cloud strikes. Landing three scatters activates Temptest with 8 free spins and between 1 and 3 strikes. Four scatters trigger Maelstrom, awarding 10 free spins where double and triple strikes are common. Five scatters launch Godstorm with 12 free spins and up to 2 strikes; the multiplier ladder is richer with larger values appearing more frequently. Six scatters naturally landed activate Olympus Rage with 15 free spins using a royal ladder and premium-only Mystery Rain. Olympus Rage retriggers grant 4 additional spins per 3 or more scatters, up to a maximum of 24 extra spins.
Bonus buy options are available: Storm Watch (1.25x bet), Storm Chase (1.5x bet), Temptest (100x bet), Mystery Storm (128x bet), Maelstrom (150x bet) and Wrath of Zeus (200x bet).
