Hammer of Thunder by Spadegaming uses a 6-6 layout with a 97% RTP and medium volatility. The top win is x66.

Bet range runs from USD 0.2 to USD 500, accommodating low- to high-stake play.

Mechanically, the title relies on cascading symbol evaluation with Avalanche mechanics and a Cluster Pays structure, allowing repeated symbol clears and multiple pay opportunities across the reel set and spins, while maintaining predictable landing patterns. Scatter symbols trigger bonus rounds, accompanied by a multiplier that can apply within those rounds, increasing potential payouts on subsequent cascades and contributing to action persistence across the session. Wilds and Sticky Wilds improve board coverage, while Respins extend chances after non-winning spins, contributing to extended play sessions and more frequent retriggers. Additionally, a random multiplier interacts with a Free Spins multiplier during triggered events, offering episodic boosts when multiple features align. Taken together, the configuration yields a mechanically driven experience with balanced payout potential and recurring opportunities.
