Let's begin with a little bit of basic knowledge about slot machines.
Modern Slot Machines work on a computer program that randomly selects winning combinations. Winning percentages and odds are set by manufacturer and are calculated by millions of spins made with computer simulations.
A Slot Machine is a mechanical device employing three, four, five, or more circular reels of varying dimensions. Each of these reels has several symbols, either painted on or attached to it. Most common designs are Cherries, Bars, Jackpot Symbol, and Number 7.
Theme Machines are very popular, using red, white, and blue 7's symbol which trade on American patriotism. To better understand Slot Machine Strategies and how Winning at Slot Machines can be easy, you must first know what kind of Slot Machine you are playing and understand Slot Machine Strategy.
Three Reels vs. Four Reels
Common sense should dictate that it is far easier to line up three matching symbols for a Slot Machine win, than four. To get four of anything is very hard, even on liberal Video Poker. On a Reel Slot Machine, three 7's can be achieved much more often than four 7's on a Four-Reel machine. Look for Three Reel machines to play.
Progressive Slot Machines are usually Four-Reel machines which offer an open-ended jackpot that increases in value after each pull on every machine within a linked group. The top jackpot can be won only if maximum number of coins is played and all winning symbols correctly line up on pay line. Progressive Slots do not pay off very often, however if you want to play a Progressive Slots, pick one whose Primary and Secondary jackpots are at a high level.
Two-Coin vs. Three-Coin Machines
In a Two-Coin machine, for top jackpot, or maybe even top two or three jackpots, second-coin play will pay considerably more than just double one-coin jackpot. For example: top jackpot payoff on a Two-Coin machine is three 7's, paying $1,000, same three 7's pays only $400 if you played only one coin. The Three Coin machine will show much higher payoffs for top jackpots with three coins played. Three-Coin machines might look more lucrative in their payoff than Two-Coin machines, but don't be fooled! The player also has to bet more to get higher payout. Consequently, player will lose more money. One final piece of advice: whatever slot you play, Two-Coin, Three-Coin, Four-Coin, etc., always play maximum number of coins. If you don't, you are not maximizing your winnings.
