Free spins are generally a risk-free way to enjoy slot games in an online casino. However, there can be downsides. Often, free spins come with wagering requirements, meaning you must wager the winnings a certain number of times before they can be withdrawn. Additionally, there may be a cap on how much you can win from free spins. Finally, free spins are usually valid for a specific game or set of games, limiting your choices. Always check the terms and conditions of the promotion to fully understand any potential downsides.
