This is a great free brain training and concentration game. What you have to do is to switch off all the lights.
It is not as easy as it sounds. You switch one and the one next to it switches off too. So you have to be carefully not to leave only one light on. If you can’t find the right combination and play more than 5 minutes the game automatically ends.
If you make more than 200 moves the game ends as well.
