I to like to play craps as a cover for blackjack. I would have your wife make only these 5 bets which are the ones I have taught my wife when she started out. 1-pass line with odds.2-come bet with odds.3- dont come bet without odds. 4-place the 6. 5-place the 8. When taking odds take the maximum you can afford to cut down the house edge. Hope this helps. LOL
only bet pass line with an odds bet as high as the table allows. those are the only 2 non sucker bets you can make. dont pass betting is more complicated..
