This is a very addicted trivia game.
In every round there is a moving ball move from origin to the edge , and a static ball put in random position within the circle.
When you press screen , the moving ball will cycle a circle , if the circle can collide with the static ball , you get 1 point.
Looks easy but difficult to get high score , you need judge the distance between static ball and origin , then press screen at the correct time when the moving ball has a same distance to origin.
Leaderboard supported , challenge with your friends!
Two theme of game : day and night , to protect your eye.
