I have been enjoying your Blojin game enormously (http://www.ctkmathgamesforkids.com/Relax/Blojin.shtml). A nice logic game that me and my daughter can both attempt.
But we are completely stuck at level 7. It seems to be impossible to go any further. I've also asked a couple of friends to have a go, and the've also got stuck at this point.
Is it possible to complete level 7?

Thanks for any tips?

Jose
