Enigmo is a cross platform game made for Mac/PC http://www.pangeasoft.net/enigmo/index.html
I Believe that i think it is a game made directly for aspies/auties/pdd-nos'ies with its very simple and intuitive gameplay, bright colors and uplifted sounds and lots of different things to play with...
The gameplay is dubiously simple, simply get the bright colorful liquids into their correct containers, faster you do it the more points you get!
I suck at doing it quickly, but its very fun to watch everything move in the way you invented it, the physics are completely dynamic so you will never invent it in the same way you did before! there will always be a slight variant!
sometimes its fun just watching all the movement

When in doubt, ask an autistic. Chances are, they're obsessed with what you need to know.

Autism Speaks will NEVER speak for me
