• The option to share Cogismo logic problems with your friends. Both iPhone and Android versions of the app are available

• Both online and offline play are supported. You could do all 270+ of these addictive puzzles while your phone is in flight mode

• English language in-app help, a two minute in-app tutorial, and a website with tips on how to solve these brain games

"Cogismo is a great concept. It's tough! Very tough" - Tom Cutrofello, puzzle app reviewer at GottaSolveIt.Blogspot.Com

The Rules :

1) When you tap on a cog:
- that cog will rotate 90 degrees clockwise; and
- the number being displayed on the cog will be incremented by one.

2) The cogs have teeth. When a tooth on a rotating cog strikes a tooth on another cog, then the other cog will behave just as if you had tapped on it (i.e. it rotate and be value being displayed will be incremented by one).

3) The puzzle is solved when all nine cogs are displaying the number zero.
