Freezing game on halftime

How long are you playing the game for before this happens? Also what troubleshooting you did to date? What is your phone make/model, and its free storage? Did you clear the cache (you should be able to do it from app settings since you marked Android).

Make sure you link your account to EA account or FB before you start troubleshooting further.

It happens time to time, I always clear my cache.. I have a lot of free storage on my phone. I linked my acc to EA acc. 

I noticed that the game does slow down over time due to probable memory leaks (a common issue in many applications), so when it looks like its slowing down, just restart the game and carry on.

I do restart game but I still  lose  cups too
