The sports betting market continues to expand more and more by the month, which means players are inundated with betting bonuses to choose from, especially if you are completely new to online sports betting. Whichever betting bonus you are searching for, OddsPortal has a long list for you to choose from, ranging from free bets, cashback, matched deposits, bet and get offers, and more.

By registering with our recommended online bookmakers, you are guaranteed to receive your betting bonuses, provided you use our offers to sign up and register for the first time. All you need to do is follow the betting offers for new customers we have supplied on this page, and then follow the instructions provided by the bookmaker to claim your betting bonus.

Apart from a select few bookmakers offers which might be tailored for significant sporting events and only eligible for a specific sport, you can use your betting bonuses for odds on football, tennis, american football, boxing, basketball, or any other sports that you like.

What Is a Betting Bonus?

A betting bonus is funds you are rewarded, usually, for registering with a new bookmaker, but they are however not withdrawable cash but something that you can only use to place bets. Claiming a betting bonus typically entails finding an offer that you like with a bookmaker you haven’t registered with before, signing up as a new player, meeting the qualifying requirements for your new customer offer, before you are then awarded the amount specified in the welcome offer.

A betting bonus isn’t always for new players though, with existing players also able to claim betting bonuses, sometimes on weekly occasions with certain bookmakers. Quite often you will see betting bonuses available if you wager a certain amount or more each week.

How to Decide The Best Betting Bonus For You

Deciding which betting bonus is best for you will depend on the type of offer you are looking for, how much you want to stake, and plenty of other factors. If you are somebody looking to deposit either nothing or as little as possible to secure betting bonuses, then you will most likely want to find no deposit bonuses or a bet and get bonus.

Alternatively, somebody looking to stake big might be more interested in a cashback bonus, or deposit match bonus which matches the cash amount you decide to add to your new account.

We suggest that you browse through all of the suggested betting bonuses at the top of this page and, provided you are a new player with the recommended bookmaker you are interested in, click on our claim button, register and meet the qualifying requirements of that welcome offer.

How To Claim Betting Bonuses

Each bonus you decide to claim will be different depending on the bookie you decide to sign up with, but there are steps that will cover each and every betting site listed below:

1. Click on the “CLAIM BONUS” button for your preferred bookmaker from the recommended betting bonuses at the top of this page
2. Sign up by entering details like your name, address, email address, and any other required information by the bookmaker
3. Either be awarded your betting bonus if it was a no deposit offer, or make the minimum deposit required as laid out in the promotion
4. Place a bet at the minimum required odds and with the minimum amount of selections applied
5. Receive your betting bonus within the timeframe specified by the bookmaker thanks to signing up with OddsPortal!

How Do Betting Bonuses Work?

Now you have claimed your betting bonus, you will undoubtedly be eager to use it on sporting events that are on currently. But do you know how to use your betting bonuses? Depending on how the betting bonuses have been allocated in your account and the sign up offer you decided to claim, you will be able to use your betting bonuses on one specific sport with a specific bet type, or on any sports that you want.

If you have chosen to claim an offer which specifies you can only use your betting bonuses for football accumulator bets or bet builders for example, then that will be what you are able to bet on. If you are just receiving betting bonuses for any sport, then you will just need to add what you want to place a bet on to your betslip, and then choose your bonuses for that bet.

For any winnings that you receive from bets placed with bonus funds, you will not receive your stake back as cash, unlike if you placed a bet with your deposited money. Also depending on which welcome offer you decided to claim with OddsPortal, you will have a set of funds added to your new account to use freely in how many installments you choose or it could be as 3 set amounts of bonus bets, which may influence how you bet with your betting bonuses.

Once redeemed, your betting bonuses will have an expiry date so make sure that they are used before that date is reached and they are no longer available to be used.

Are Betting Bonuses a Sports Betting Sign Up Offer?

The betting bonuses that we offer on this page are reserved for those registering as a new player only, and they fit into the sign up offers category. The reason for this is because only those of you who are creating an account with our recommended online betting sites can claim them, with such lucrative promotions only able to be claimed once.

Depending on where you are located, you will be presented with numerous sign up offers that you can claim, but they are all eligble for new players only. This means that if you have already registered with our suggested betting sites, you will not be eligible for any of those select sign up offers.

There are several different betting offers that you are able to claim under the promotions sections of the online betting sites we recommend, but you won't be able to find them on this page.

New Sign Up Offers 2025

All of the betting bonuses that we recommend are updated offers for 2025, meaning that you won't find any promotions that are out of date or no longer accessible. We always want you to have the best betting deals and sign up with bookmakers to claim a large chunk of bonus funds for you to use on your preferred sports.

It depends on which bookmakers you decide to register with through OddsPortal, because some choose to change their welcome promotion quite often, while others will offer a continuation of the same offer for a longer period of time, especially if there are no significant sporting events upcoming.

We always look out for our players and ensure we are providing you with the best gambling site offers with each of the online bookmakers that we have available on our platform. In some cases, we will even do our best to offer you exclusive promotions that see you earn bigger betting offers than you can find at other sites or even with the bookmaker's standard offer.

Types of Betting Bonuses Available

Betting bonuses can come in many different forms, and here at OddsPortal we have split up our betting bonuses into specific pages so you can find exactly the type of offer you are looking for. In order to claim betting bonuses you might be required to make a deposit, or place a bet, while in other cases you can even be rewarded with a betting bonus with no deposit.

Check out some of the types of betting bonuses you can expect to see with bookmakers below:

Welcome Offers

A welcome offer is reserved for players registering with a bookmaker for the very first time, and these are the most common type of betting bonus that you will find with OddsPortal. A welcome offer itself can be many things, and any of the betting bonuses listed below, but it is simply available for new players only.

Deposit Bonus

A deposit bonus is a type offer that requires you to make a deposit in order to claim your bonus funds from the bookmaker you have chosen to bet with. There may be specific requirements with a deposit bonus, meaning you might need to deposit a select amount to guarantee you receive the betting bonus available with that chosen bookmaker.

Additionally, a deposit bonus could also refer to a deposit match when registering with a new bookmaker, or even as an existing player. For example, you may receive a 100% match of your first deposit in betting bonuses when you sign up, which would be considered a deposit bonus.

No Deposit Bonus

A no deposit bonus is what players would love to find with every bookmaker because it would mean you get to place bets on sports without having to spend any money first. However, a no deposit bonus is quite rare among sports betting sites, with them often preferring for players to make a deposit first.

Bet and Get Bonus

Bet and get offers are the most common type of bonus that you will find with bookmakers, and they are exactly what they say they are. When you meet the qualifying bet at the required odds and with the specific amount of selections necessary as stated in the terms and conditions, you will then be granted your betting bonus with the selected bookmaker.

A bet and get bonus is something that will sometimes be available to existing players too, for example matching your bet on a specific game in bonus funds once you opt-in to the promotion.

In the UK at the moment you will find bet 10 get 30 offers are quite commonly available, while in the US you will typically see bet 5 get 150, or sometimes more at the time of big sporting events.

Betting App Bonuses

To encourage you to join through their app and to ensure you download it to your phone, some online bookmakers can offer ehanced promotions for new players that are signing up with the app. Similarly, they can offer you other incentives when already registered to download the app, if you haven't done so already.

To discover some of those exclusive betting app bonuses that you might be able to claim, you can check out our betting apps page today and find out which sites in particular have an app and any new offers they might have available.

Cashback Bonus

Cashback bonuses are when you are rewarded with a percentage of your bet in bonus funds if you lose. This type of betting bonus can be for new players or existing users, meaning you will either win cash if the outcome of your bet is a win, or receive a percentage of your stake as cashback either in real money or as bonus funds.

Crypto Betting Bonuses

With OddsPortal, you are now able to claim specific sign up offers for crypto betting sites, if you are somebody that prefers to place bets using digital currency. We offer you the opportunity to sign up with various crypto bookmakers, including Cloudbet, BC.Game, Coins.Game, and more.

Crypto betting bonuses will typically vary in comparison to standard offers at online bookmakers who use standard currency only, but it can sometimes be even more lucrative to claim this type of offer with much bigger bonuses available.

Betting Bonuses For Existing Players

Betting bonuses will also be granted for existing players because bookmakers will be keen to encourage players to keep revisiting and playing at their site or app. For existing players, betting bonuses can be rewarded in numerous ways. An offer for all players could see them be rewarded with a matched bonus for a bet on a specific day or days, while in some cases bookmakers will gift players with a betting bonus just for loyalty purposes and for regularly placing bets.

For example, bet365 is well known for allowing players to claim bet credits as a loyalty bonus for regularly playing on the bet365 website or bet365 app. Promotions for existing players don’t always require players to stake real money though, with certain operators sometimes granting bonus funds to players for specific events or allowing them to participate in free to play games throughout the week to secure some potential betting bonuses. Alternatively, betting bonuses for existing players could be on a weekly basis for placing a certain amount of accumulators, or bets on a specific sport.

Just some of the betting bonuses for existing players to look out for and claim include:

In-Play Betting With Sports Betting Offers

Betting Sites With Welcome Offer Terms and Conditions

There are a few things to be aware of when claiming a betting bonus, especially if it is a bookmaker you are registering with for the first time, simply because there will be specific requirements you need to meet. In some cases bookmakers will make clear what the requirements are to claim a betting bonus, but others can put details in the fine print that could easily be ignored.

Just for clarification on what is required, always make sure you read that fine print to get an understanding of what the offer entails and what you need to do to secure a betting bonus with that given bookmaker. We always recommend that you check the terms and conditions when claiming any betting bonus to ensure that you are aware of what is required of you when you sign up, and to make sure that you don’t place any bets which will not contribute towards claiming your betting bonus.

Even with promotions for existing players, you need to check the terms and conditions to ensure that bets you are placing will qualify when it comes to claiming your betting. Similarly, you will probably be required to opt-in to claim a betting bonus as an existing player. Don’t just automatically assume you will be rewarded, first make sure whether you need to opt-in before placing any bets.

Some of the key factors to consider in the terms and conditions are:

• Minimum deposit
• Minimum odds
• Accepted payment methods
• Betting bonus expiry dates

Which Sporting Events Can I Use Betting Sign Up Offers On?

The sports or particular events that you can bet on using bonus funds all depends on the terms and conditions of the sign up offers that you claim through OddsPortal. For example, there might be certain betting bonuses made available around significant events like the World Cup, the return of a new Premier League season, or at Wimbledon.

Hopefully, the betting offers that you decide to claim are either available for any sporting events, or for the specific event that we have talked about above, with those types of promotions typically only being made available when a highly significant event is either on or upcoming.

Always ensure you check the terms and conditions of the betting bonuses we recommend, to avoid there being a situation where you are unable to use it on your preferred sport or particular competition.
