About this Slot
Grave Voltage is a horror, zombie and sci-fi themed slot from Nexo Games with an RTP of 96.31%, high volatility and a maximum win of 10,000x. The game uses 5 reels, 4 rows and ways paylines.
Rise lands on reel 1 and triggers a collect when monster heads appear on reels 2 to 5. A full stack of Rise symbols multiplies the collected total.
Overcharge lands on reel 1 and charges the values on reels 2 to 5 with multipliers ranging from ×2 to ×6. In the base game, Overcharge lasts for one spin. During free spins, Overcharge persists across spins and builds further.
Reanimation Spins trigger when three or more Scatter symbols land. The feature expands the grid to 5×5, increasing ways to 3,125. Larger Rise stacks become possible during Reanimation Spins, and Overcharge multipliers remain active throughout the feature.
Storm Ante boosts the chance that Scatters land and increases the likelihood of triggering Reanimation Spins.
Rise Strike is a one-spin feature purchase that loads a 5×5 board with collect symbols. The feature guarantees both Rise and monster head symbols, and awards wins on regular ways additionally.
