Slot Machines do not have any code which can be cracked to win. Today Slot Machines are computer-programmed to choose a winning combination in a random manner. The manufacturer of these machines establishes the winning percentages and odds are computed by millions of spins made with computer simulations. A Slot Machine is a totally automated machine. It has three, four, five, or more circular reels of different sizes. The usual symbols painted on the reels are Cherries, Bars, the Casino Jackpot Symbol, and the Number 7. The colors red, blue and white 7’s symbols are popular with theme machines.

Three Reels vs. Four Reels

Getting an array of three matching symbols to win on a Slot Machine is easier than four. You can win on a three-reel machine more than a four-reel one.

Two-Coin vs. Three-Coin Machines

In a Two-Coin machine, to receive the top two or three jackpots, the second-coin play will pay considerably more than just double the one-coin jackpot. The payoffs on The Three Coin machine are much more for the top jackpots than for the Two-Coin machine. But here the player has to bet more to get the higher payout but on the other hand, will also lose more money. Whatever slot you play, Two-Coin, Three-Coin, Four-Coin, etc., to maximize your winnings you should play the maximum number of coins.

Progressive Slots

Progressive Slot Machines are usually Four-Reel machines that offer an open-ended jackpot that increases in value after each pull on every machine within a linked group. You need to play the maximum number of coins and all the winning symbols correctly arranged on the pay line to win the big jackpot. It is advisable to play on a machine where the Primary and Secondary jackpots are at a high level.

One Payline vs. Three Paylines

Most Slot Machines have the Centerline marked as a pay line. For you to win, the winning combination has to line up on that center payline. But some machines show Three Paylines: at the top, center, and bottom of the window indicating you can win on any of the three Paylines that has a winning combination. The chances of winning on a Three Payline are higher and you can get double and triple wins if winning combinations appear on more than one payline at the same time. One shortcoming is that the payoffs are generally very small and the top jackpot is paid only if you line up the proper winning symbols in the correct sequence on the bottom payline. Another disadvantage is that Three-Payline machines are always three-coin machines. Some machines offer five, or even eight Paylines but, once again, you have to play five or eight coins per pull. It is most profitable to play the Two-Coin maximum, Three Reel, and One Payline Slot Machines.

Double-Up Symbols

A few Slot machines contain Double-Up symbols on their reels which have a circle or a diamond in a circle with the words “Double” painted across it. This indicates that the payoff amount is double and these Double Symbols can be substituted for any other symbol. You will find such machines either at the end of the casino or mixed among a group of bad machines.
