Fun but too many glitches

Great games. Needs more variety like blackjack. If you win plus trigger the bonus round on slots you dont win the regular credits only bonus ones. If I buy extra credits it loses the credits I already had: had 1100, buy 75000, credits =75000 not 76100... Please fix the glitches!!
