Crix Gratuit app for iPhone and iPad

The iPhone game Crix is a collection of puzzle sets. Your goal is to turn off all the buttons. The problem is, every time you touch a button, all the neighboring ones are also switched! Blue ones are switched off, white ones are switched on. Can you find a way to get a white board in a minimum number of moves? Crix comes with 40 different layouts, of increasing difficulty. The early levels are fairly easy. They help you learn the techniques you will need to solve the later levels -- which, though simple looking, are surprisingly challenging. The random mode offers endless possibilities of layouts with a chosen difficulty. And there are other possible customizations. Can you make it?
