Some werid happened to Hi and Ho recently - they were kidnapped into a gaint maze! In order to escape from the maze, they need to program and caculate all kinds of possible ways by their laptop! And this is the Battle of Hi & Ho!

The first thing they met, is a minefield! And the evil builder make this minefield's rule exact like the mine-sweeping game of Windows. Little Hi and little Ho need to know the exactly position of all mines so they can safely pass through. But, is this really possible?

Little Ho's analyse about week #31 is about to publish in few days!
