May be this is a silly question but I do not have an algorithmic background.
I am trying to understand how this game http://www.psdevwiki.com/ps3/Scogger_HD generates an arrangement of the trunks so that there is always a way to make jump over all of them.The most significant rule is may be that the frog only move in the direction its facing.
Can someone help me understand how to randomize the location of the sprites while still ensuring there was a not obvious path around each piece.
