High Roller
A gambler who consistently wagers large amounts – a big spender in the betting world. High rollers often receive VIP treatment from casinos due to the sums they bet.
A **high roller** might bet \$50,000 on a boxing match. For instance, a wealthy fan drops a “dime” (or ten dimes) many times over – such high-stakes bettors can even move odds with their heavy action.
