Best Bookmakers Bonuses in Sweden in 2025

What Are Betting Bonuses?

As the name suggests, sports betting bonuses are incentives offered by sportsbook operators when you join, reload your account regularly, or make certain types of wagers. They offer value and give bettors an edge compared to wagering with their own money. On the other hand, betting sites use betting bonuses to attract prospects and retain regular bettors.

It’s important to understand each type and the possible merits and downsides; we’ll cover them all in this guide. Also, you’ll find each type comes with different kinds of restrictions, such as betting on certain games or betting multiple times before you can withdraw your winnings. Read on as we break down the best bookmakers’ bonuses in Sweden and help you find the ones that are best for you.

Best types of sports betting bonuses

Below are the types of betting bonuses you can take advantage of during specific sporting events or seasons, such as the Super Bowl or March Madness. Use them to boost your winnings regardless of which sport you wager on.

• Welcome Bonus

Welcome bonuses are always present when you register on a new sportsbook and collect the benefits that accompany new registration. Most online sportsbooks offer two types:

• Deposit Bonus: Online betting sites offer new clients bonus funds of as much as 1,000 Kr after they make an initial deposit into their account. Usually, the more you top up with, the greater the deposit bonus you receive.
• No-Deposit Bonus: Only for the lucky few, but if you get one, you can add more value to your betting funds. It’s not as simple as it seems, as they usually have high and strict wagering requirements.

• Free Bets

A free bet offers a specific amount as a wager. They don’t have cash value, and the stake isn’t included in any winnings.

• Cashback Bonus

Cashback bonuses are an excellent way to boost your bankroll after a week or month of losses. Online betting sites offer regular bettors an event-specific cashback or a percentage, often 10% or more per week or month, for their losses.

• Accumulator Bonuses

These are exclusive sports bonuses where the betting site raises the payout odds and allows a bettor to bet on simultaneous events or multi-legs. Look for them around popular events like the Super Bowl, the NBA playoffs, or a Champions League match.

• Refer-a-Friend Bonuses

The friend-referral bonus is awarded when you invite others to join the platform. It matures once your referral uses your code to sign up and deposit funds. It includes cash prizes, free bets, and free spins, which can be shared between you and your referral.

• Reload Bonuses

The reload bonus gives you back a portion of all the wagers you make, a deposit match, or a portion of your losses. These bonuses are a good gift if you’re cautious about risking large sums.

• Loyalty Programs

Loyalty programs are VIP incentives for consistent bettors. They usually involve money prizes, VIP trips, private customer support, and faster payouts.

• Risk-Free Bets

This is a no-sweat bet where you get a bonus or your money back as a free wager if your team loses. They offer a form of insurance and are great on events with bigger payouts.

• Task-Based Bonuses

These are engaging offers that require bettors to target high-stakes events or accomplish different wagering tasks to receive a stake in the form of a free bet or bonus cash.

Bonus Terms and Conditions

Betting is about rules, and the following are some terms and conditions you should pay close attention to when choosing sportsbook bonuses. They include:

• Maximum Win - Betting sites place limits on the maximum amount you can win to protect themselves against losses. This is also known as a bonus cap.
• Minimum Deposit - Typically, you must make a qualifying deposit as a new user to access welcome promos. Different sportsbooks offer different minimum deposits.
• Payment Method Restrictions - Before claiming any sports betting offers, check the site’s payment guidelines. Most sites support instant banking, e-payment services, and crypto.
• Betting Limit - Your wager must meet specific criteria to unlock most bonuses. It refers to the number of times the bonus must be gambled on before you can withdraw any winnings.
• Game Restrictions - Every sportsbook offers bonuses for selected games. So, read the terms and conditions carefully.
• Bonus Expiry Date - This refers to the duration for which a sports bonus is valid. Most bonuses last more than 7 days, but you can always confirm with your sportsbook as each varies.

Much of this information is found under sportsbook bonus terms and conditions on their official sites. Always compare the terms carefully to unlock the bonuses and maximize your winnings.

Tips for Beginners

While gambling at online casinos is always down to your luck, there are certain things you can do as a beginner to get the maximum benefits out of the best bookmakers’ bonuses in Sweden.

• Bet logically - Arguably the first rule of betting is to never spend all your bonus funds on one market or slot. Be wise and spread your risk for huge potential winnings.
• Safe betting - You’re still learning the gambling world. Bet on events with reasonable odds and make use of risk-free bets, if any are available.
• Understand wagering requirements - Before accepting any bonus, carefully scrutinize the small details. Always pay attention to the wagering requirements and see if you can keep up.
• User-friendly site - Since you’re new to the online betting scene, choose a sportsbook with accessible markets, clearly explained bonuses and simple ways to claim your winnings.

Bonuses are enticing at first glance, but many have terms and conditions that are difficult to reach. Thoroughly read the terms and conditions, and if you hit a bad patch, take time out or change the sport you are betting on instead of doubling down.
