From the accent, in Japan,there is Ninja who undertakes their mission secretly.
To complete the hard job, they never give up their hard training.

Now, I would like to show you one of their trainings, The Ninja kick, on the app.

The Ninja kick is a training not to touch a sharp prickle which is partially located on the ball as it roles.

As they do the training, they train their stronger spirit, quick and good reflexes, and their eyesight to recognize things that moves so quick.

They have to be very serious about it or they will injure themselves and risk at their life as a Ninja...

I wish you all overcome this sever training and become a real Ninja!

[How To]
When the game start, the ball which has a prickle starts rolling.

You press "蹴(Kick)" then, Ninja kicks the right side of the ball.
Kick the ball when it has no prickle on the right side.

As you kick perfectly, the level will be advanced. Rolling speed will be faster, or the number of prickle will be more so it will be more difficult.

Train hard, and let me see your result at a higher level!
