Expanding symbols are symbols that grow to cover more spaces on the reels, often filling an entire reel or connecting neighboring positions to create bigger wins.
They expand when a symbol lands during a spin or as part of a feature like free spins or wild reels, typically triggered by specific symbols or game rules.
RTP is a fixed figure for the game, but expanding symbols can alter hit frequency and volatility, changing how often big wins occur.
They can appear in the base game or during bonus features such as free spins, depending on the game’s design.
Forms include full-reel expansions, stacked expanding symbols, and giant symbols that span multiple reels, each offering different win opportunities.
Expanding symbols can produce large wins, but jackpots are separate features and not guaranteed by expansion alone.
Expanding symbols generally can occur at any bet level when the feature triggers; some games may vary how often they appear with different stakes.
