Sol Reactor

Sol Reactor is a space-themed sci-fi gems slot from Sunnie Gaming with 7 reels, 7 rows and cluster pays mechanics. It has an RTP of 96.7%, high volatility and a maximum win of 25,000x.

Winning clusters trigger cascading reels, which remove winning symbols and allow new ones to fall into place. Expanding symbols grow to fill larger areas of the grid during cascades. A multiplier increases with each cascade within a single spin sequence.

The Charge Meter builds from wins, accumulating a minimum of 8 charge per win. As the meter fills, it unlocks bonus doors at specific thresholds. When the meter reaches 100 charge, the Ember Core bonus triggers. At 200 charge, the Corona Core bonus activates. When it reaches 300 charge, the Supernova Meltdown bonus is triggered. Mid-charge boosts reshape the grid during base play. Any charge exceeding the threshold carries over to the next fill. Each time the meter completes a 100-charge cycle, an extra spin is awarded.

The bonus round uses a Reactor Core multiplier system. Solar Flare orbs increase the Reactor Core value during the feature. The Reactor Core multiplier only increases throughout the round and never resets. Every 100 charge accumulated during the bonus triggers a random event.

Five bonus buy options allow direct access to features at set prices: Ignition at 3x bet, Solar Storm at 50x bet, Ember Core at 150x bet, Corona Core at 400x bet, and Supernova Meltdown at 1,000x bet.
