Reels
Reels are the vertical columns in a slot game that spin when a game round starts. Each reel displays various symbols, and once they stop, the arrangement of symbols determines if a winning combination is formed according to the game’s paytable.
Most online slots use 3, 5, or 6 reels. Generally, more reels mean more paylines or ways to win, often resulting in higher volatility.
3 reels slot: typically classic slot with simple gameplay.
5 reels slot: the most common format in modern online slots.
6+ reels slot: slots that use modern reel mechanics like cascading or expanding.
