This is a simple puzzle to test your boolean logic skills. Eight dots sit in a circle, some on and some off, and most of them connected to other one or more other dots. Tapping on a dot jolts its connections, toggling all dots it is connected to while leaving the dot you touched unchanged. Your job is to toggle all the dots to the off state. Sound simple? Not really. When you give up you can watch the puzzle solve itself in embarrassingly few steps.
The full name of this puzzle is "Dastardly Doctor Devios Disturbingly Diabolical Dots"
