A high-roller bonus is a special type of casino bonus offered to players who bet more money. This type of bonus is likely to be a part of a loyalty program offered by the casino, or might be a welcome bonus, or could even be a stand-alone offer.
High-roller bonuses are usually much higher than typical casino bonuses, and the player must bet far more money to qualify for these kinds of bonuses. The rewards for these bonuses are often substantially higher than those found with regular casino bonuses.
