I can help you a little card buddy.
My tips -
1. stay away from the fixed betting games, like BJ and roulette. You cant raise your bet, and as the house has a 52% advantage, you will not end up ahead.
2. I also advice against the one line slots. Not enough time to hit a win for the amount you will need to put in.
3. I go for the multi line bonus slots, like tomb raider and beach party, mermaids millions e.t.c, ill explain why.
There are multiple lines, so lots of ways to win. There are free spins, hit these spins adn allw ins are tripled, and if u bet the fixed maximum, the spins win is between $50 and $150 normally. There are bonuses, wild symbols, its all there for a win.
HOWEVER, if you find a slot you like. sont stay on it. When you get that win that puts you above your starting balance by $50. leave it instantly, ive stayed at the same slot for ages and ages and never got a run of any of them, but if i move they all seem to pay out a biuggish win pretty soon after starting your frist spin.
SO to sum up
Avoid card games and video poker, play multi line video bonus slots, choose one, play it till you are $50 up ish, then leave and find another. Keep this up till the time runs out, or if its our Platinum Play bonus, then simply stop when you are $200 up i suggest
