The reset/"restart" button is at upper right.
An interesting game. Should not have double arrows on each side, since the side arrows only turn the board one way. Should have a one-way arrow on each side, to show which way it turns. The timer should count up, not down, with lower time=better score. On Kong, people spend time in chat. The reset/restart button is not clear enough. The ball is too hard to find at the beginning. The ball looks too much like the star and the checkpoint. So, it needs some interface work. But it is an interesting game. 3/5 as it is, but could be 4/5.
