What exactly is a Bonus Slot:

To actually understand what a Bonus Slot machine is, you should first know the difference between casino bonuses like Free Spins and Bonus Slots with features like free games.

A Bonus Slot with a free game Booster is a feature that gives you some bonus spins and a special game mode while the main game is in progress. These modifiers usually get triggered when you successfully perform certain actions, like landing a specific symbol in combination, etc.

You don't need to comply with any extra requirements or conditions for these bonuses as the bonus games are a part of the main slot game. Hence, you keep all the winnings you get during the gameplay.

Online Bonus Slots compared to Casino Bonuses

Casino bonuses like Free Spins on certain specific online slots are a promotion tool used by online casinos to attract players. Most online casino operators offer lucrative welcome bonuses to players who sign up with them for the first time. These welcome packages usually contain some Free Spins, which you can use on certain fixed slot titles.

You get these Free Spins when you complete the registration and verification process at a casino. These bonuses often come with some requirements that you should meet before you can enjoy the bonuses. These requirements contain prerequisites like minimum deposits, etc.

Usually, most Free Spins in offers like these contain a minimum deposit requirement. However, some online casinos also offer Free Spins that are a part of no-deposit bonuses. In offers like these, you just need to create a gaming account at the iGaming venue, and you'll immediately get the spins. As this bonus doesn't require you to add funds, there is no need to worry about making a deposit.

These features let you freely explore modern online slots without having to worry about your deposited money. The interesting thing about these Free Spins is that even though you are not putting anything at stake, you'll get real money in the form of winnings if you land successful combos on the games. Some casinos also let you use these spins on multiple titles, and you get a good general idea of how an online casino actually is.

Free Spins offerings are not just limited to new players. Loyal and existing customers can also enjoy them. Online casinos keep on offering exclusive bonus bundles and limited-period offers to their customers so that they also get some freebies and stay loyal to the venues. These bonuses are usually given on a weekly or monthly basis. There is no specific way or format in which online casinos offer such bonuses, and it depends on a particular venue. To get the complete details about such bonuses, you'll have to visit the casino's promotions section.

Remember that these promotions come with certain terms and conditions which you'll have to comply with in order to use these bonuses. Wagering requirements are usually there in almost every Free Spins bonus. These requirements ask you to gamble a certain amount of money on the online casino before you can take your winnings out via different banking methods.

Before starting your gambling session, the first thing you should do is to check the venue's license. If the casino is licensed by the concerned iGaming authority, then the place is safe to gamble.
