Sports betting bonuses present a lucrative opportunity to boost one’s bankroll; however, choosing a bonus requires careful consideration. Similar to casino comps, bonuses are designed to attract more customers to an online sportsbook. While the sports betting industry has experienced notable advancements, the fundamental principles remain unchanged. Bookmakers leverage bonus offerings as a primary marketing tool to promote their services.

We have provided a subjective ranking of the most reputable sportsbooks and their bonus offerings. It is important to note that the sportsbook ranked number one may not necessarily offer the largest “true bonus” percentage, even if they offer a maximum bonus cap of $2500. The “true bonus” can be calculated by determining the percentage divided by the rollover requirement.
