I rarely win, BUT I seem to have an uncanny ability to pick slots for DH to win on. I swear, when we walk past a bank of slots, I scan them and many times tell him to "play that one". More often than not, he will win on it.(meaning he gets quite a bit more out totally than he puts in).
Sometimes if I am wandering around I find him and tell him to come play a certain slot. If he's already on one he likes, he says"no, wait a minute"..but I insist...he wins...I NEVER say "I told you so"!
