Chess, with 9 different levels, so you can test your levels exactly.

Currently first 3 levels are open and later 6 levels are in in-app purchase.

For each level, you have to win 3 consecutive times to pass. After all levels passed, you are the same level as professional Chess player.

This is also a facebook free app, the url is here:

All levels are open in facebook.

For the buttons, they are:
1) rate, to rate the app in app store
2) mail, to invite friends to play this app
3) restart, to surrender and restart a new game

4) full version, to buy the in-app full version.

This is a professional test, no undo!
