About this Slot
Sphere City is a space, gems and sci-fi themed slot from AVA STUDIO with an RTP of 95.42%, high volatility and a maximum win of 10,000x.
The Core Wild substitutes for symbols S1 through S9 only, and does not replace Bonus or Hit symbols. The Nexus Frame is a highlighted grid zone that appears randomly during the base game and remains active throughout free spins.
Three Bonus symbols trigger the Nexus Bonus, which awards 10 free spins and starts with a 2×4 frame. The Nexus Bonus carries any base game wins into the bonus total.
Four Bonus symbols trigger the Nexus Hypercore, which also awards 10 free spins but starts with a 3×4 frame instead.
During free spins, the Nexus Frame is always active. A four-level ladder tracks Bonus symbols collected during the feature. Every 3 Bonus symbols advance the ladder by one level, adding one frame column and 3 additional spins with each advance. The frame can expand up to a maximum of 6 columns.
The Rift feature activates when a transformation creates a winning line. If the Rift occurs outside the frame, the entire reel turns wild with a multiplier applied. If the Rift occurs inside the frame, it transforms a full block.
