A multiplier is a slot feature that multiplies a payout by a set factor, such as 2x, 3x or 10x. It is one of the most common mechanics in slot machines and video slots, and it comes in several forms:
- Base game multipliers, often paired with cascading reels: each consecutive win in the same spin raises the multiplier, and it resets as soon as a cascade brings no win.
- Free spins multipliers: they can stay active for the whole bonus round and reset only when play returns to the base game.
- Symbol multipliers: wilds or scatters that double as multipliers and boost any win they help to form.
Multipliers have a big effect on a slot’s volatility, because they concentrate value into rarer, larger wins. That is worth checking in the paytable before playing a game, and before adding one to a casino lobby.
