No, you cannot directly block someone on Coin Master. But there are ways to limit their interaction with you. One option is to unfriend them on Facebook. This will prevent them from appearing in your Coin Master game.
Another method is to activate ghost mode. This mode makes your profile invisible to others, limiting their ability to attack or raid you. This can be very useful if you want to play without interference.
If these methods don’t fully solve your problem, consider adjusting your privacy settings on Facebook. Make your Coin Master activity visible only to certain friends or just yourself. This way, you can control who interacts with you.
These workarounds are not perfect but can help make your Coin Master experience more enjoyable. Choose the method that best fits your needs and play without unnecessary interruptions.
