We are aware that some of our players may be experiencing an abnormal drop in their coin balance in 8 Ball Pool.
We are advising everyone to play a quick match or play a mini-game so that this visual bug is reverted and you are able to see your correct coin balance once again!
We're really sorry for the inconvenience this might have caused you and if you still need help, please don't hesitate to contact Player Support!
We'll be glad to help! :)
