A high-roller bonus is an incentivized promotional offer that is geared towards attracting premium players. It is usually offered to players who are willing to make larger deposits and wagers than what is considered as the average. These offers can take the form of welcome bonuses, deposit bonuses, reload bonuses and various other promotional offers.
In order to benefit from a high-roller bonus, players need to meet the qualifying criteria which will usually be more stringent than for regular bonus offers. Moreover, qualifying deposits will usually require far larger amounts. On the other hand, when players do qualify, they can expect premium rewards in the form of extra bonus money, free spins, loyalty points and even luxurious gifts.
