Trying to become a ninja takes a pretty long time you have to play and win at least 80 times untill you get the black belt all you have to do is pick a card and say you have picked water and the other penguin picked fire u would win!

Fire Beats Ice

Ice Beats Water

Water BeatsFire

Just keep playing until you win! When u are black belt play sensei after about 5 gos you would of won just dont give up
