Slot machines are actual free-standing "machines" easily identified by their spinning reels and pull handles. The concept is simple, drop in some coins, pull the handle and hope the reel symbols line up. Different symbols win different amounts, and there's usually a jackpot available to be won. Slot machines are a total game of chance. There are no rules to learn, and the outcome is totally random. The ease of play, the potential huge payoffs, the noise and the excitement level around the slot area all contribute to a high entertainment value for some. Slot machines come in a variety of forms with diverse symbols on the wheels and numerous payout systems. Slot machines can have from three to five reels/wheels and one to five payoff lines. In all of them the basic idea is the same, to line up particular symbols on the payout line. The less likely a combination is to occur, the greater the payoff. The most basic slot machines require you to bet one coin (a fixed amount such as a dollar), they have only three reels, only one payout line, and pay a multiple of the bet coins value (e.g. Three cherries on the payout line will result in a payout 300 times the bet coins value). The player inserts the coin and pulls a handle (or presses a button on the front panel) and waits for the wheels to stop on the payout line to see if, and how much they have won (the payout symbols and payoff values are posted on the front of the machine). The more complex machines accept more than one coin (up to five), can have up to five wheels, and many also have up to five payout lines (three across and two diagonal). .
