Question: Should I make the bonus bet?
Answer: Absolutely. Granted, the bonus bet is optional, and you can still have fun and win some good payouts without it. But the bonus bet adds a lot of excitement, as well as the biggest payouts, to the game. If you make the bonus bet and get a royal flush, you win the progressive jackpot, which has now passed 86,000 credits and is still growing. And even without a Royal Flush, you can win jackpots ranging from 4 credits for two pairs up to 2,500 credits for a straight flush. That's a lot of cash to be won for a small 1-credit side bet.
Question: When should I hold 'em and when should I fold 'em?
Answer: If your initial hand has a pair or better, stay in the game. Also, if you have four consecutive cards for a potential straight, or four of the same suit for a potential flush, stay and draw for the winning card. With anything else, cut your losses and fold 'em, and hope for better luck next time.
