How To Become A Ninja

It is not that hard to become a ninja using a few tricks. All you have to do is beat the other penguin's card by guessing fire,water, or snow.
It is sort of like rock paper scissors.
Water-w fire-f snow-s b-beats

if you both play the same card type, the higher number wins unless there is a small icon in the bar at the top that looks like the second screenshot

                                              that means if you play the same card type, the lowest card wins.

It's that simple to do. The trick is when you're playing a rel opponent you would choose whatever would lose to their current card. Also really it's better To just make another penguin and have it on a separate computer if you have two, and purposely lose, so you always win. It's just a matter of repeating this. Last, NEVER play on the mats or you will not gain as much experience. Good Luck!
