1. You light up-process one of the inner lights - going counterclockwise so that it will match a lit one outside. Example: yellow.
2. Do the next inner light clockwise until you get the same colors side by side lit outside (anywhere): For example - yellow and yellow. They should be in pairs only.
So inside and outside are now yellow:yellow.
3. You do the next adjacent light (click until a reaction outside is seen - can be other colors will cause reaction too). Find out that yellow (from previously lit) and a new one you're working on (maybe green) will light up - yellow and green outside.
So inside (rhe last 2 will be yellow:green). You then light up or look for yellow:green outside.
4. Work on the next one beside green now and so on.... until the whole circle of lights are lit.
