and dont forget puzzles are item lvl 31 so you can get a toon to lvl 31 and use it to gamble rings. monk, crus, dh and wd are best bcs they only have 3 rings in the loot pool at 31. the other classes wiz, necro and barb have 4.
if you do this you will have so many puzzles youll not even bother with killing greed just tap all the piles of gold grab all the gold and gems and just ignore everything else
