What Expanding symbols mean?
The symbol expands to cover the full reel. One hit can thus cover an entire vertical line at once.
Why these games?
A mechanic is listed only if it is marked in the game's own feature list. We do not infer mechanics from videos or ads.
Does this mechanic raise the RTP?
Not automatically. RTP is a game-specific figure and is stated separately on each game's page. The mechanics tell how wins are formed — not how often they occur.
