Thunderer

Thunderer is a Greek mythology slot from Mythik with 96% RTP, high volatility and a maximum win of 25,000x.

The game features cascading reels that trigger symbol upgrades and bonus play extensions across multiple bonus rounds. Expanding wilds grow down their reel until they hit the bottom, another wild or a special symbol. Wild Explosions expand into a 2x2 block of wilds, while Golden Wild Explosions expand into a 3x3 block. Wild Multiplier symbols act as wilds with values ranging from 2x to 1000x, boosting any connected wins. Max Lightning acts as a wild and guarantees the maximum win whenever a winning way includes it.

Mystery symbols reveal as the same random symbol type. Splitter splits winning symbols to create additional ways, adding one extra way per split. Wild Flame transforms one random symbol type into wilds, and Fire Pot removes all royal symbols from the board.

Three scatters trigger Thunder Plays with 10 bonus plays. During this round, symbol hits fill a power bar; when the bar fills it resets and upgrades the lowest symbol.

Four scatters trigger Zeus's Gift with 10 bonus plays. The winning symbol multiplier starts at 1x and doubles with each win. Three scatters landing during this feature award 5 extra plays.

Five scatters trigger Treasure Temple with 10 bonus plays. Each winning connection grows one random reel by 1 position, up to a maximum of 8 positions per reel. Five consecutive tumbles in one play awards an extra feature.

Six scatters trigger Fire Plays with 10 bonus plays. When a symbol hits, the grid multiplier at that position doubles; only multipliers under winning symbols count, and multiple multipliers on one win add together.

Bonus Builder increases the likelihood of triggering a bonus round by over 5x. Multi Blast activates a multiplier grid where special wilds land more often. Zeus Special awards 3 guaranteed random special symbols.
