Multipliers, or additional coefficients, are most often used in slot machines, but can also be used in other casino gambling games.
Multiplier – the coefficient that increases the standard payout.
In slot machines, multipliers can be used in different ways. For example, payouts for combinations with jokers can be doubled or tripled. Often, additional multipliers are used during free spins or re- runs.
Such odds are sometimes endowed with other prize functions. For example, the multiplier can be progressive.
