The term "hit and run" is a term found throughout the world of gaming that describes when a player stops playing whatsoever immediately after a big win. Thus, instead of continuing to try their their luck some more, he or she just discontinues. Some hold this form of playing to be rather short-sighted as the player ignores the option of playing further so as to possibly achieve bigger wins. We'd recommend that you give yourself a break after a big win before you decide between playing further or just plain quitting while you're ahead, so to speak.
