Types of Bonuses

There are several types of casino bonuses offered to real money players. These generally apply to specific scenarios, like the first deposit. The purpose of these bonuses is to reward players and encourage them to bet. Winnings can be withdrawn in adherence to the wagering requirements in the terms and conditions.

No-Deposit Bonus

If you're short of cash and want to access online bonuses, players can sign up for a no-deposit bonus which allows you to play for a day or two. Once your total "winnings" have been calculated, you must keep playing to release the money. Typically, you'll have to "wager" the winnings a certain number of times. Clearing this type of bonus can be easy for regular slots players.

Welcome Bonus

New depositors at an online casino can also use slots to work off a welcome bonus. A welcome bonus is a "match deposit" paid by the casino. If you deposit $100, and the casino matches it 100%, you can win back $100 free. You will have to wager the $100 first, usually 20-40 times, but most online slots contribute 100% of their play towards the bonus amount.

Leaderboard Tournaments

Casinos love to pit slots players against each other. In a standard tournament, you might have to accumulate the most profit from 20 consecutive winning spins. Whoever gets the most "profit" wins the leaderboard. A real money jackpot will be spread out among the top five or ten leaderboard finishers.

High Roller Bonus

Players who want to deposit a large amount of real money can benefit from exclusive deals aimed towards high rollers. These have higher limits, allowing players to get more bonus funds for free. If a standard welcome bonus reaches $100, a high roller bonus can exceed $1,000.

Reload Bonus

Existing players can continue to receive regular bonus deals, often in the form of reload bonuses. These apply to the deposits made after claiming the welcome bonus. Reload deals are usually sent by email to registered players or promoted on the website.

Game-Specific Bonuses

New game releases or special events sometimes come with exclusive bonuses for one or more gaming options. For example, players can receive free spins for a selected online slot machine to trial it before spending real money. Bonus funds can also be awarded for specific games.

Device-Specific Bonuses

Nowadays, more players enjoy their favorite games on mobile devices. Casino operators look to reward customers by offering mobile-exclusive bonuses. These can only be claimed from a compatible smartphone or tablet on the site, or through the casino mobile app, if available.

Percentage Deposit Bonuses

Percentage deposit bonuses are widely available. They give players extra funds based on their deposits. In many cases, the percentage can increase and even exceed 100% for big deposits. Clients are encouraged to make larger transactions for the best deals.

Casino Bonus Terms and Conditions

Before making a deposit to claim a bonus, it is highly recommended that players scrutinize the related terms and conditions. These should be clearly displayed and present the general rules of getting the offer. Here, you can check important factors such as the wagering requirements, the minimum deposit needed to get the bonus, and whether certain banking methods are excluded.

Some bonuses might require promo codes or might only be available on certain days. The terms and conditions will include the games on which the bonuses can be used and if there are any restrictions.

How Wagering Requirements Work

Wagering requirements, also known as playthrough rates, are included in the terms and conditions of most casino bonuses. They prevent players from withdrawing the bonus and running away with it! Instead, the funds must be used to bet on eligible games until the requirement is met.

When it comes to slots, this is usually between 35 and 50 times the initial bonus. Other games generally have lower contributions or none. For example, a 100% bonus of $100 with a 50x wagering requirement means that the player must bet a total of $5,000 before withdrawing their real money winnings. Normally, the wagering must be completed within 30 days.
