Go to playstore look for the redeem option ,enter the code in the card,go to coc buy gems ( make supercell richer ,and greedier) enter your google password and BAM you got gems and supercell make a fat profit thanks to you and they continue to hide dead bases 4ever,but dont worry is not your fault is their
