A game that's more difficult than it might seem, this one is based on clicking sequentially numbered circles to clear each level. The oval buttons to the right are ordered in increasing level of difficulty: easy, medium, hard. They correspond to the number of circles you must click within the time limit to clear a level. For example, when the game begins, click on the circle with 1, then 2, then 3... not too difficult, eh? You try it.
