Shorting your play time in gambling is the best strategy in gambling, apart from knowing how to manage your bankroll, don't spend too much time on a casino game, the longer the time you spent the more you lose, this is the truth that many gamblers won't accept at first until they realize it later.
That's true. Because in order to play longer, a gambler needs a decent bankroll (unless you're lucky to win and never got busted early). Everytime I gamble, I have a set budget and that's the only amount that I should use in playing. If I lose early, there's no extension and I have to stop. But sometimes I was able to play for like an hour or two because i'm lucky in the game that I chose.
It's fine to stay long if you're still using your set budget and not keep on depositing just to sustain your eagerness to keep playing. Discipline and self control are important so you won't go beyond your limit.
