The very first slot ever played was nothing more than three rattling barrels with cards glued to them; if the gambler hit a winning combination, then they had to tell the bar manager who would pay them with bevereges or a meal.
Today gamblers betting online can be overwhelmed by the thousands of different slots titles available. Online slot machines varie from the classic 3-reel game to multi-line video slots.
Online Classic Slots
Classic slot machines borrow on the simple three-reel format that characterized the first slot machines. Generally these games have only one pay-line down the center, and gamblers must line up three matching symbols in the game window in order to win.
Online 5-reel Slots
5-reel slots were the first variation made on the classic three-reel . The end result is more symbols, more possible combinations and more pay-lines. To get the big prize, 5-reel slot gamblers must line up all five symbols on a paying line, though often combinations of as few as three or even two consecutive symbols still pay.
Online Bonus Slots
A bonus slot is any machine that offers a side prize for achieving a certain combination. At times the bonus game is just a series of free spins, other times it’s an animated scene that ends in a randomly generated prize, and still other times it’s its own interactive mini game. Online slot machines offering bonuses generally have a special bonus reel that must appear in a predesignated area or order to initiate the bonus game.
Online Progressive Slots
Progressive slots are any slot machine that is connected to a system wide jackpot – they can be any of the above types. Progressives are generally connected to a group of same or similar slot machines that are arranged in banks.
The progressive jackpot grows with every wager, but to win it a gambler must be betting max credits. While most progressive jackpots are worth a few thousand dollars, some online progressives frequently get up to a million or more.
Online Video Slots
Video slots were the first slot machines to replace the actual reals with a computerized screen. Though most video slots still emulate the look and feel of a classic slot, some spin side to side or drop blocks instead of spinning reels. Video slots allow gamblers to bet on 20 or more different pay-lines and also paved the way for in-game bonuses.
