Online poker bonuses are promotional offers provided by poker sites to attract new players and retain existing ones. These bonuses can come in various forms, such as welcome bonuses, deposit matches, and loyalty rewards. Typically, players must meet specific wagering requirements or play a certain number of hands to unlock these bonuses. They enhance the gaming experience by providing extra funds or tournament entries, allowing players to explore different games and strategies without risking their own money. However, it's essential to read the terms and conditions to fully understand the bonus structure and maximize its benefits.
