Florida Para-Mutual Wagering Bond ($50,000) Parimutuel betting differs from fixed-odds betting in that the final payout is not determined until the pool is closed � in fixed odds betting, the payout is agreed at the time the bet is sold. Parimutuel gambling is frequently state-regulated, and offered in many places where gambling is otherwise illegal. Parimutuel gambling is often also offered at "off track" facilities, where players may bet on the events without actually being present to observe them in person.
