Winning makes us happy, while losing always leaves us regretful, that's gambling.

If you're feeling unlucky several times, it's best to stop gambling for a week or move on to another game. Because luck sometimes only comes once, and you might find another advantage in another game. Honestly, I've gotten really bored of playing slots and rarely play them anymore, as that's the cycle I've always experienced. I now prefer card games or roulette, which I find more profitable.
