In both online and normal casinos however, there is some truth that the higher denomination machine payoff slightly more often than the smaller denomination machines. The nickel and quarter machines usually pay the least, while the larger denomination machines pay off the most often. This makes sense, it encourages play on the machines which bring in the most money.

For simple slot machines where you simply bet one coin and pull the lever/push the button there really is no strategy, you simply pop your money in and wait for the reels to stop. Just remember to play at a level you can afford. Take your wins when you get them, accept your losses, and enjoy yourself.

These slots are the type of machines that allow for multiple coins to be played. There are two different basic types:

1. On some, you can increase your odds of winning by increasing the number of payout lines. Each coin played adds another payout line up to a maximum of five, three horizontal lines and two diagonal lines. The machine will pay out on winning sequences on all lines you've bet on.

2. On others, you can increase the payout on winning depending on your bet. For example, if one coin is played a payout might be 200 coins, 500 coins for two coins played and 1000 coins if a third coin is played. The best strategy for these machines is to play the maximum numbers of coins, because assuming you win the same number of times the additional payout percentage makes you more money.
   
   Think about stepping down a level if you want to limit your wagers, it is smarter to play a quarter machine using maximum coins rather than to play a dollar machine using one coin.
