*** Ranked first in France and Brazil ***

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! Colorful ones are switched off, black ones are switched on. Can you find a way to get a white board in a minimum number of moves?

Crix comes with 160 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?

BEST there is...

I'm an avid fan of logic puzzles & an "app junkie." Have had Crix for several months & it has a permanent place among my fav puzzle apps; it's the BEST there is of this type of game!

I LOVE the graphics with glowing, cycling colors and AMAZING REPLAY VALUE!!!

With 4 difficulty levels AND 4 options to change the pattern the surrounding circles turn on/off, it continues to keep me entertained whether I pick it up for a few minutes or a few hours.

Very responsive & active developer, maintaining game with updates & new levels to keep app fresh - something many find difficult to come across! (I promise I am in absolutely no way associated with this dev!)



Good brain teaser

There's definitely a problem though... For some reason the bottom row won't recognize my tapping it. Everywhere else does. And it's not my phone because it works just fine in every other app and such. I have to press the bottom row like 20-40 times in order for it to recognize my tapping it.


Mind-boggling fun

This game is a great way to pass the time if you're bored. The levels become incredibly challenging and it makes you feel like a genius when you finally finish one you've been stuck on. A simple and entertaining game for all to enjoy.
