jaya7 — Slot categories
Themes, grids and special features are separate parts of a slot. jaya7 compares classic-symbol formats with video-slot structures here.
Context and practical meaning
Classic fruit and bar symbols retain the language of older machines. Video slots may use similar symbols alongside different lines or animation.
Paylines recognise combinations in specified positions. Cluster formats may count adjacent groups instead; their calculations should not be treated as identical.
Starburst provides a concrete video-slot example. Five reels, three rows and wins in both directions illustrate its structure.

Recognising the situation
Gem imagery around a machine conveys a theme. The rules specify the actual grid and active lines.
Stopping-reel animation presents a result. A near match does not promise a win on the next spin.
Details that change the decision
A wild can substitute for ordinary symbols, with exceptions. It should not be confused with a scatter or bonus symbol.
Respins and free spins are different features. One can repeat play after a trigger; the other may provide a separate set of rounds.
RTP is a long-run theoretical measure. It does not promise the same proportion back during an individual's short session.
