why the battery runs down when I play a game, even if he is at the charging cord. ??

I have been swapping the original power cord of 80 cm for a power cord 150 cm

 

it is a 10 Iconia Tab A3-A40

That happens when the AC charger has not enough power (ampere) to handle the tablet consumption and if the USB cable is a cheap one or  the battery controller has a low setting on the amount of power charge to prevent overheating.

 

using an higher ampere output charger will not solve your issue, since the battery controller will controll the amount of power charge to prevent overheating (and you can't set this)

 

if you device is under warranty i would suggest to contact Acer support service, just to be sure it's not  an hardware fault.
