Yes, most - if not all - Ghanaian online sportsbooks offer welcome bonuses to new customers as an incentive to sign up and start betting. Welcome bonuses can come in various forms, such as a deposit match bonus or free bets, and they are designed to give you extra value when you start betting. To claim a welcome bonus, you usually need to create a new account and make a qualifying deposit, while also meeting any other T&Cs attached to the bonus. It's important to note that welcome bonuses can vary between online sportsbooks, so it's always a good idea to compare offers from different operators to find the best one for you.
