Those wondering about getting $250 => Laticia wants $200 , the taxi to Latiicia's house is $50 hence the $250. If your maximum is $295 , then you even have $45 to spare. I don't understand why the issue there.
Those of you that are having problems beating Laticia at the game => Laticia will always have more than 17. If your card is below 17 , then click Hit me until you are between 18-21. Sometimes you will of course lose because it all depends on luck but it is not as difficult as it sounds once you figure it out. You can keep playing all the time until you beat her without her asking for additional money.
