Go round space jet-ball stations as much as possible and get higher score.
Jet-ball is a kind of pinball.

You have 5 balls in a game.
Use jetting devices to blow the ball off by tapping somewhere on the screen.

The game has five kinds of stations.
You visit them as a course which is repeated with additional gimmicks.
Clear some conditions to pass the stations.

The conditions are
1st station : making "GO!" by touching the green panels
2nd : breaking all four magic balls
3rd : putting the ball in a center tub by kick-up boards
4th : touching green columns ten times

To go to the next station, put the ball in the red zone.
Then you get 10000 points.
(Touching the green panel , robot guard and green column is each +100 points.)

The 5th station is nothing to do.
Though you lose 20000 points and minus 2 station counts if the ball touches a rockfall. It only depends on your luck.

According to the count of passed stations, the tourist grade is displayed with high score at the game over.

As additional notes,
1. When the ball gets out of the stage, a next ball appears from a certain position on the stage.
(The ball's move is affected by the previous ball's.)

2. When the ball is brought to a standstill, please try double-tapping which adds a little force to the ball.
(The count of passed stations is displayed at the same time.)

3. If you like to restart during the game, please long-press somewhere on the screen (about 3 seconds).
A “RESTART” button appears when your finger is lifted.

I hope that you will enjoy it!
