There is a new math game available from CTY, it is called Descarte's Cove. It consists of 6 CDs and is recommended for kids in grades 6-8.

Anyone here familiar with this game?
Specific questions - how long does it take to master each level? I know that IT DEPENDS, but rough estimates would be appreciated.
How do you/your kids like the game? How is it different from what you have seen before? Does the fact that it was developed by CTY make it a "gifted" game?
