Lunar Disc is an IGT video slot with a six-reel layout, developed as a follow-up to IGT's earlier Solar Disc video slots. Fortune Disc is a related title in the same visual and mechanical family covered by this guide. Both are built around a central 'disc' symbol-collection meter that sits above the reels and pays off once enough matching symbols have been gathered, giving the games a distinctive look on the casino floor compared to a standard reel-only cabinet.
The signature feature of this family is a large disc displayed prominently above or beside the reels. As matching Lunar Disc (or Fortune Disc) symbols land during play, they contribute rings or segments to that meter. Once the meter fills, the disc itself spins independently of the reels and lands on a symbol, which then turns every matching symbol on the reels wild for that spin -- a mechanic designed to build visible anticipation as the meter fills over a session.
IGT built Lunar Disc as a spinoff of its earlier Solar Disc slots, carrying the same core disc-meter idea into a night-sky, moon-themed presentation. Fortune Disc sits in the same broader family of disc-meter titles IGT has released under different visual themes, giving operators a set of related cabinets that share the same underlying feature logic while offering players different artwork and music to choose between.
Because the disc mechanic rewards any matching symbol landing anywhere on the reels rather than a specific payline hit, these games tend to build toward their bonus gradually and visibly, with the meter itself acting as a running indicator of how close the feature is. That makes them a popular choice for players who like being able to track bonus progress at a glance rather than a bonus that can trigger without warning.
