A 200% deposit bonus is an enticing promotional offer commonly found in online casinos and betting sites, where players receive double the amount of their initial deposit as bonus funds. For instance, if a player deposits $100, they would receive an additional $200 in bonus money, giving them a total of $300 to play with. This type of bonus enhances the gaming experience by providing more opportunities to win, but it often comes with specific wagering requirements that must be met before withdrawing any winnings. Always read the terms and conditions to maximize your benefits.
