would be a game your wife won't ever complain spending money about,
especially if you can hold your promise to play ONLY with it from now on
and forget about the real casinos.
It is one game that you can surely
beat if you have good memory (or if you cheat). It can hardly turn you
into the next millionaire gambler, but it can surely eat the time until
the next airplane while keeping the real money in your pocket.
