Kissing Circles
Descartes · 30 levels
Fill the gaps of a fractal with whole-number circles.
How to play
- Every circle shows its bend: bigger bend, smaller circle. The big outer circle bends the other way, so its bend is negative.
- A gap between three touching circles takes the circle with bend 2 × (sum of the three) − the circle on the other side.
- Tap the right bend in the tray to grow the glowing gap's circle. A wrong bend costs a spark ✦; lose all three and the gasket resets.
The circle on the other side touches the same three circles. Watch the minus signs: taking away −1 adds 1. A hidden “?” circle sits in a gap too, so work it out first.
