Slot machines will be the most popular game in both online and land-based casinos. But, casinos tend to be searching for ways to keep people playing them more often and playing them longer. A proven way of accomplishing that was creating multi-line bonus games.

These multi-line bonus games were developed in Australia and came to the country in 1996. Instead of the traditional 3-reel, single-payline format, these slots usually have up to 5 reels and 25 paylines. Instead of one payline going horizontally as with traditional slots, with multi-line slots you can get a payout going horizontally, vertically or diagonally. Multi-line slots have a larger selection of symbols, since you'll find more lines, and each has another value. In land-based casinos, most multi-line bonus games are video slots.

Multi-line bonus slots have symbols called scatter symbols. These are symbols that unlock some special bonus round, a mini-game where the player has the possibility to win bonus prizes at no risk. Unlike other symbols, they don't have to be within the active payline to be counted. Bonuses are a clever way to keep people playing the game, as many people shall continue playing regardless of whether losing cash on the hopes of hitting a bonus.

professional slot game bonuses come in a wide variety. Sometimes they come within the type of free spins, extra coins to wager, free points (in the event you are playing in a point-based tournament) and more. Bonuses are the best chance players have of recouping their losses, even though on the subject of slots just about everyone will lose in the end, anyway.

The bonus rounds unlocked by the scatter symbols come in many different forms. Sometimes 3 to 5 objects appear on the screen and also the player must choose one, receiving whatever bonus is affiliated with that object. It's kind of like the old "see what is behind Door #2" game show trick. In other cases, a scatter symbol for a free spin will turn up and you are automatically given a no cost spin without playing any bonus game. Another common bonus game is a matching game, where there's a grid with hidden symbols and if you match two symbols you are given a particular bonus.

Some bonuses are offered in the type of banking. Here, players accumulate bonuses throughout the course of the game and rather than using them right away, they are banked, where they are added together and in the event the bank reaches the specific goal, it is paid out to the player. In this particular system, players are rewarded for playing the game for a longer time frame. With online slots, the bonus games are more complex. They usually share a theme with the slot and have more of an interactive type of gameplay. Some examples include batting practice in a baseball-themed game and trying to knock out an opponent in a boxing-themed game.

Whatever the sort of bonus game, multi-line bonus game online slots are wildly popular. After all, everyone loves to get free stuff. Hitting bonuses gives the players the top chance of making their money back and gives them a feeling of accomplishment, which is essential any time you are pumping a lot of coins into a machine.
