Types of Slot Bonuses

The best online casinos offer generous bonuses for both new and existing players, most of which you can claim and use on online slots. Our experts have summarized some of the most common slot bonuses below.

Welcome Bonus

A casino welcome bonus is a promotion for new players to entice them to sign up at an online casino. You can get many of the rewards listed below as a welcome bonus, including free spins, deposit bonuses, and no deposit bonuses.

Free Spins

When you claim a free spins bonus, an online casino will reward you with a set number of spins on particular slot games. Sometimes, your winnings from free spin offers can be limited, but these promotions still give you a chance to spin slot reels and make a profit.

Deposit Bonus

A deposit bonus, or a deposit match bonus, is where an online casino will equal a percentage of your deposit with bonus funds. For example, an online casino could offer a 100% deposit match of up to $300. If you deposit $200, you’ll get $200 in bonus funds, giving you $400 to use on slot games. Most deposit bonuses are available as a part of a welcome offer and will have wagering requirements.

No Deposit Bonus

Unlike other promotions on this list, you don’t need to make a minimum deposit to claim a no deposit bonus. Instead, your online casino will reward you for opting in or completing your registration. These bonuses are great for beginner players who want to try out gambling without risking their money.

Reload Bonus

A reload bonus is very similar to a deposit bonus, as the online casino will match a percentage of your qualifying deposit with bonus funds. These promotions are often available for existing players to boost their bankrolls.


With a cashback bonus, an online casino will pay you back the money you’ve lost playing eligible slot games with bonus funds. You can use these bonus funds to continue playing slot games and withdraw any profits once you complete the wagering requirements.

Slot Bonus Terms and Conditions - What You Need to Know

Nothing is truly free in the online casino world. Every online casino promotion will have terms and conditions to consider, which you’ll need to abide by while redeeming your slots bonus. Many casinos use reasonable T&Cs to ensure players can’t take advantage of generous bonuses. Below are some of the most common terms for slot bonuses.

  • Wagering requirements: As discussed, wagering requirements tell you how many times you need to use your bonus funds before withdrawing. The higher the wagering requirements, the harder it is to walk away with a profit. Low wagering requirements are best if you want to make the most of your slot bonuses.
  • Game exclusions: Some bonuses are only eligible for particular games, whereas others may exclude certain game types like progressive jackpot slots. The best promotions are available for the broadest possible range of games.
  • Payment method restrictions: Many online casinos will prevent you from claiming a bonus if you use ineligible payment methods. Fortunately, the most commonly accepted payment options are bank cards like Visa and Mastercard.
  • Minimum deposit: Many slot bonuses have minimum deposits you need to meet before you can claim your offer. The best slot bonuses will have low minimum deposit requirements, so players on any budget can enjoy them.
  • Maximum bonus amount: The maximum bonus amount tells you the most value you can get from an offer. Top slot offers will offer you thousands of dollars worth of bonuses to play with.
  • Time limits: Many online casinos will put time limits on you using your promotions. You’ll never get through your bonus funds if you claim an offer with massive wagering requirements and only seven days to complete them. Look for the offers that give you time to enjoy your promotions.
