You may not have updated your page and that's why you thought you had 4 Rounds left when you didn't. You can always check the number of Rounds played in theaccount history; for that you must go to the "My account" section at the top right of thehome page, then toaccount history". 😉
slt why I am told that I have 4 free rounds left when when I want to Play well it just tells me that I have already played all my free rounds? not nice it is useless to have 15 if you can only Play a few of them... help me please
