This bonus offers you a free spin, which means that you can wager on a particular game for free. They're used for different things. In a casino free spins can be a bonus that introduces players to a new game. It's sometimes also used as a reward: You keep playing the same game and receive free spins for that. Free spins offered by a casino are usually limited either by the number of spins or the time they are valid for.

Online gambling sites depend on bonuses to attract new players. Competition is fierce, there are operators in the thousands, and sites need to offer added value to players. Without these special deals, visitors will simply move on to the next site. Most of the promotional offers are of course connected with a player's registration. New users are usually offered the most generous deals. Some operators match a player's initial deposit, for example. The player makes a deposit of $30 and has $60 to wager on games. Sometimes the bonus is just a percentage, sometimes it's a fixed sum.

Players who stick with a favorite site for a longer time will receive loyalty rewards. These are actually quite similar to the offers made to newcomers, but usually not quite as generous. Again, usually the player can choose from several plans including percentages of the deposit made as well as fixed sums.

Rewards for playing the slots are almost as old as the gambling machines themselves. Special buttons or levels on the slot allow the player a free spin for playing the game over and over again, and of course these are added to today's video slots as well. Although mostly connected to the actual number of pulls, there sometimes are special buttons. Many casinos have free spin rewards every week, every day, every month or connected to some special event. Christmas is a popular excuse to add gimmicks to a game, so are official holidays or traditions such as Halloween. In any case, it's worth keeping your eyes peeled and look out for the best ones.
