CLUBPENGUIN!!!!!!
You beat the sensei by getting your black belt. You have to have that before you can beat him then after that just keep playing him like five times and the ninja room is all yours!
No, you can not beat Sensei without the black belt. if you try he will beat you every time. You have to become a black belt to play a fair game. Hope this helps! What is above is a really bad answer, but i still don't know how to beat it
You just have to go and fight him in the dojo because he will always use different cards.
To beat the sensei,you have to be a black belt. You constantly have to try again,and again to beat him,because he gets weaker every time you lose.
Its not imposible i won agenst him Brineplup ---- Aim me at 12:30 to 1:30 Joeykoen2089
You need to keep playing Card-Jitsu until you earn up to the black belt. Then, challenge the Sensei and if you beat him, he will make you ninja.
