CONTROLS: Drag circles with your mouse. Click a circle to select it.
Selected circles can be moved with the arrow keys (for higher precision)
GOAL: In Level n, all n circles with radius from 1 to n must be in the big circle without touching each other or the big circle border.
If the circles with radius 1 to n are not located in the big circle, the big circles border will be red.
Otherwise it will be green.
If two circles touch each other, there will be a line between their centers.
The problem is solved if the background becomes green.
