Chani I keep a Pages document for Diggy info, when I need to note tile colours, tile numbers, tile images to link up to solve a puzzle.
With the crazy puzzles that SEEM to go in circles, I would try different things like trying to go back to see if it went somewhere new. Two steps same direction, then backup, go alternate blue link. Stuff like that. I solved the puzzles - hey, I am in Greece and only have last Poseidon mine to complete, with first Ares mine having just opened.
