A 200% deposit bonus is an enticing promotional offer commonly found in online casinos and betting sites. When players make a deposit, the platform matches it with an additional 200% in bonus funds, effectively tripling the initial amount available for play. For example, a $100 deposit would yield $300 in total funds to wager with. This bonus enhances the gaming experience, providing players with more opportunities to explore games and increase their chances of winning. However, it's essential to review the terms and conditions, as wagering requirements may apply before cashing out any winnings.
