Pool betting is a type of betting where everyone puts their money into a shared pot. The key difference from regular fixed odds betting is how the winnings are decided.
In fixed odds betting, you're betting against the bookmaker, and they set the odds. You know exactly how much you'll win if your bet is successful.
In pool betting, everyone's stakes go into a common pool. The operator deducts costs and a profit, and then splits the remaining money among the winners. The payout, or "dividend," isn't fixed beforehand—it depends on how many people picked the winning option. If fewer people chose the winner, the payout is bigger because it's divided among fewer people.
