Combine three descending numbers to create sums of 10 or 20. Create enough combinations to fill all of the balls at the top of the screen. One ball is filled if the sum is 10 and two balls are filled if the sum is 20. The health bar at the bottom of the screen reduces when you create a sum that is over 10 (and not equal to 20) or let a number fall below the dotted line.
Left click on the numbers to combine them.
