You have played 40 out of 40 games in squad battles for this week. There is a counter to the right top corner that says that. You can keep playing the games for coins but You wont be given any more points towards the squad battle rank. Two featured squads ( some celebrity and TOTW ) do not count to the 40 number so technically there is 42 games that You can play to get rank points. Also you have to remember if You refresh the squads when You did not play all the games from last refresh You will loose the chance to earn more pints and the counter will go up.
