The single-roll bets are just ridiculous: an 'any 7' bet pays 4:1 and provides the house a whopping 16% beginning.
As being a guideline though always stuck to the basic bets you know and for one of the most part don't use the proposition bets and you'll be fine. http://customer.cntexnet.com/g.html?payclick=0&url=http://aiki-evolution.jp/yy-board/yybbs.cgi%3Flist=thread
