Is there a way to beat the odds on a slot machine?
You can't beat the odds - the Casino has to have the odds in their favour to pay their expenses, salaries profit.  But you can improve them.  Typically higher coin machines pay out more.  So play a $0.25 machine rather than a $0.05 machine (but play more slowly or you will lose your money faster).  Also, study the pay schedule on the machine.  Some of them require you to play full coins to get the best odds.
Because of the high interest rate, over a period of time you will owe more in interest that the actual amount of your purchase. So.....unless U file bankruptcy (which will also ruin your credit), they CAN and WILL take everything you got.
