Don't let the balls touch the bottom! Click on a ball to destroy it and get a point. Higher levels have shorter wait times between balls and have balls that fall faster. Obviously, there is a cap on wait times and ball fall speeds. You have 3 lives. Each time a ball touches the bottom, you lose a life. Your level is determined by your score. Level 2 is at 5 points, level 3 is at 15 points, level 4 is at 30 points, and in general, the number of points you need to reach level a is the sum of all numbers from 1 to a-1 multiplied by 5. Quick calculation tip: The sum of all whole numbers from 1 to n is (n(n+1))/2. A snap sound will play every time you level up.
