Welcome Denise. You will find lots of useful information here.
Tip No. 1 - Read the Terms, especially if you use bonuses.
Tip No. 2 - Expect to lose, enjoy your play. Winning is a perk, not the usual outcome.
Tip No. 3 - Never borrow money to gamble (that includes your credit cards. If you can't pay the balance off without a win, don't play with one)
Tip No. 4 - Set yourself a cashout goal at the beginning of every session. You are more likely to withdraw if you do. It can be modest (2 x your deposit), or largish (10x your deposit), or a dollar value ($100 ahead for instance). It need not be the same goal every deposit, depending on your circumstances. It can even be a length of time. But you will make more cashouts if you have a goal.
Tip No. 5 - If you have questions, ask support via chat or email - and keep copies of the responses.
Happy spinning, and good luck.
