My WiiU is frozen, what should I do?

We played Minecraft in multiplayer for two and suddenly the picture is frozen. I can't finish the software either. Simply unplug is certainly not good for the console. What should I do?

Unplug

Next time, hold the powertaste other wii u printed and then it is off

Is not there a reset button? If there's one on the console then you should press it. Whether long or short, I do not know. But actually does the same thing as plug out and in. You can try both. You should just be careful that you do not accidentally lose data.

Nope, just not
