How do no deposit-, welcome- and reload bonuses work?
Online casino bonuses come in various forms, offering players additional funds, free spins, or other perks. Essentially, they are designed to encourage players to sign up for the casino or make further deposits.
These bonuses usually come with specific terms and conditions, such as wagering requirements or game restrictions, which players must meet before withdrawing any winnings.
What is a casino welcome bonus?
A welcome bonus is one of the most popular types of bonuses, typically given to new players when they make their first deposit. For instance, Casumo Casino offers a 100% match bonus up to £100, plus 20 free spins on Book of Dead. If you deposit £100, the casino matches it with £100, giving you £200 to play with. However, this bonus comes with a x30 wagering requirement, meaning you must wager £6,000 before being able to withdraw any winnings associated with the bonus.
Similarly, PlayOJO offers a unique approach by providing a no-wagering welcome bonus. Players receive 50 free spins upon signing up, and any winnings from these spins are paid out as cash with no wagering requirements. This means you can withdraw your winnings immediately without meeting any wagering terms.
What is a no deposit bonus casino?
A no deposit bonus is another popular offer, allowing players to receive bonus funds or free spins just for registering, with no deposit required. 888 Casino, for example, offers new players an £88 no deposit bonus. However, this comes with a x50 wagering requirement.
For returning players, reload bonuses are frequently offered to encourage additional deposits. Betfair Casino regularly offers a 50% reload bonus on weekends, where depositing £100 can give you an extra £50 in bonus funds. Reload bonuses typically come with lower wagering requirements compared to welcome bonuses.
Another standard promotion is free spins bonuses. MrQ Casino often provides 10 free spins on games like Valley of the Gods or Book of Dead. These spins come with no wagering requirements, so any winnings from the spins are paid out in cash immediately. View the best offers with just x35 wager.
Finally, many online casinos offer cashback bonuses to soften losses. For example, Casumo Casino offers a 10% cashback on net losses each week. This means that if you lose £500 over the week, you’ll receive £50 back in cash, with no wagering requirements attached to the cashback amount. Cashback offers provide players with a form of insurance, giving them back a percentage of their losses over a specific period.
Understanding the terms and conditions attached to each bonus, such as wagering requirements and eligible games, is very important. There will be terms and conditions linked to every bonus. Ultimately, you want to know the wagering requirements, eligible games, and whether the bonus has an expiry date.

Wagering Requirements and Contribution Rates
Wagering terms are strictly set by the online casino. These relate to the amount you must bet in order to release winnings and bonus funds.
The playthrough requirement usually applies to the size of the deposit only or the deposit plus bonus. Wagering requirements are also applicable to free spins, though some free spins deals may carry no terms and conditions.
Most deposit match bonuses carry strict game contribution rates. That means some games will contribute more than others towards the bonus total.
For example, imagine you receive £500 in bonus funds to play on slots and games. A typical list of game contribution rates may look like this: All slots: 100%, Roulette: 20%, Blackjack: 20%, Craps: 5%, Video poker: 5%, All other games: 0%.
That means that all slots play would go towards clearing the bonus total. However, only 20p per £1 would contribute from your roulette play, and 5p in the pound for craps play.
Bonus FAQs
Absolutely. Not only are they all registered and licensed in the UK by the Gambling Commission, but they all use the latest SSL technology to ensure total protection for all your transactions.
We recommend the Betfred casino for 200 free spins. If you want a no wager or low wager free spins bonus, visit Megaways casino.
We recommend 10bet, bet365 and Betfred casino apps that offer great deposit match bonuses and free spins. Here is list of the top casino apps for Android and iOS phones.
Bet365 is one of the UK’s oldest and best-loved online casinos, with a welcome bonus to match. You can claim 50 free spins when you sign up and bet £10 on eligible games. The free spins are valued at 20p but you can unlock winnings without meeting any wagering terms.
Spin & Win offers a more traditional deposit match bonus to new sign-ups. You can claim up to £500 in matched funds when you make a first deposit. You unlock bonus cash and winnings once you’ve rolled over your bonus funds 40 times.
Very easily. Some casinos will require a code to be used to claim any offer, but this is becoming much rarer. If needed, just cut and paste the code from any search engine or comparison website and simply input it when you make your first deposit. But, in most cases, you will be automatically allocated your Welcome Bonuses and Free Spins when you deposit. There is always a minimum qualifying deposit amount, usually £10 and almost never more than £20, but other than that, claiming your Welcome gift is very straightforward.
Once you have fulfilled any wagering requirements, your winnings will automatically become available to you and you can click on “withdraw”. With more and more casinos employing the Speedy Payments system, these funds will often be in your bank account within 15 minutes.
This is the amount of times a bonus has to be played, via slots, video games or table games, before you can withdraw it as cash winnings. So, a 35x wagering requirement means that the bonus must go through at least 35 spins on a slot or table deal before it becomes “yours”. The lower the wagering requirement, the better.
