Letou's "Tennis Bet Boost" feature is designed to enhance betting opportunities for tennis fans by offering improved odds on specific matches or tournaments. When a player selects eligible tennis bets, the Bet Boost feature automatically applies a higher payout percentage than the standard odds, providing an incentive for bettors to engage with the sport. This feature typically highlights prominent matches or events and may vary based on ongoing promotions, encouraging users to take advantage of potentially more profitable betting opportunities within the tennis market.
