Hey what kind of tablet are you playing on? I would do a hard restart, here is how you do it on a ipad or an android device. 

If you have an ipad: 

Press and hold the Sleep/Wake button until the red slider appears.Drag the slider to turn your device completely off.After the device turns off, press and hold the Sleep/Wake button again until you see the Apple logo.

I hope this works for you
