Lamplighter

Press one lamp and its neighbours have opinions.

Pressing a lamp flips it and its four neighbours. Turn the whole street on before your oil runs out. It always has a solution, and each street gets harder.

How to play

• The order of presses doesn't matter.
• Pressing a lamp twice does nothing, so don't waste oil.
• Try working from the top row down.
