Bridges - online puzzle game
now... i was asking my self how can i construct a matrix that would solve a particular puzzle.
I've been breaking my head over it for hours!!!
problems I encountered:
1. n1 can connect to an n2 only if they share the same X or Y value
2. a face cannot cut another face. once a face has been created it cannot be crossed.
how would you do it? or at least, how would you start??
