Start betting at the OnlySpins sportsbook

Bonuses

• OnlySpins – Top bonuses
• OnlySpins – Top slots

First, you naturally want to check the sportsbook’s bonus offer. After all, that’s often why players choose a given operator. For registering, OnlySpins rewards you with not only a choice of two betting bonuses but also a whole range of promotions and odds boosts. Let’s take a closer look at the most interesting bonuses.

Welcome bonus: 100% up to €100

One of the two welcome bonuses you can claim at the OnlySpins sportsbook is a 100% deposit bonus on your first deposit up to €100. You can select it right on the first page of the registration form and make your start at the book a lot more pleasant. Just meet the following conditions and it can be yours.

1. Open the registration form and on its first page choose the sports bonus.
2. Complete full registration to create your account.
3. Go to your account’s deposit section and deposit at least €20. If you want to maximize the bonus, you must deposit at least €100. Deposits via Skrill and Neteller do not count.
4. You now need to wager 6× the sum of your deposit and bonus. If you play in Germany, Norway, Finland, Switzerland, or Austria, the wagering requirement drops to 5×.
5. Wagering counts with SOLO tickets with minimum odds of 2,0 and AKO tickets where each selection has odds of at least 1,50. Cash Out tickets or tickets placed with bonus balance do not count toward wagering.
6. The maximum allowed bet with an active bonus is €50. You have 30 days to complete full wagering. If you fail, your bonus funds will be forfeited.

After you complete wagering, the bonus is credited straight to your real balance, so you can use it exactly as you see fit. You can not only bet with it but also withdraw it (after meeting all conditions) or use it in the online casino.

Welcome bonus: 100% up to 200 USDT

If you’re looking for a slightly higher bonus and you’re a fan of cryptocurrencies, you can use the second alternative to the first-deposit bonus. If you choose the crypto sports bonus on the first page, you can get up to 200 USDT. The conditions are very similar to the previous case. First, you need to deposit at least 20 USDT. Then you must wager the sum of your deposit and bonus 6×. Again, SOLO bets with minimum odds of 2,00 or AKO bets with odds of at least 1,50 per pick count. You have 30 days from your first deposit to wager, and the maximum bet with an active bonus is also €50 in this case.

Other bonuses at the OnlySpins sportsbook

Of course, the OnlySpins sportsbook bonus offer doesn’t end there. Once you use your welcome bonuses, you can immediately draw on regular reload bonuses, sports cashback, or, for example, a risk-free BetBuilder, odds boosts, and other luxurious promotions that appear here regularly. It’s up to you whether you decide to use them all or, for example, prefer the bonus offers in the local online casino.

Registration

• OnlySpins – Registration
• OnlySpins – Login

If you want to dive in and really bet on your favorite, you’ll first need to go through the full registration process. It’s very simple and anyone can handle it, regardless of whether they’ve ever played at a sportsbook. You start by clicking the “Registration” button in the top-right corner of the sportsbook. Then, from the registration form, first pick your bonus and proceed to the next page. There you’ll enter your email and password and agree to the sportsbook’s terms. Continue again, and on the last page of the registration form, fill in all your personal details. Once you’re done, just confirm and your account is created.

Account verification

Of course, it doesn’t end with basic registration. If you want to start using your OnlySpins account to the fullest, you must also go through full account verification. The casino support will request it if you attempt a withdrawal or if you want to deposit a larger amount of money. When that happens, you have 30 days to provide all the necessary documents, otherwise your account may be deleted. At that point, just send the casino support a photo ID (passport or ID card) and address confirmation (utility bill, bank confirmation). Once support receives these documents from you, they will process them within 10 days and you can then play without restrictions. If they find any discrepancies, they will contact you.

General information about the company

• OnlySpins online casino review

The OnlySpins online sportsbook is operated by DREAMLINE VENTURES SRL, headquartered in Costa Rica. In addition to OnlySpins, it operates a number of other online casinos. However, its license is not from Costa Rican authorities but from the Tobique Gaming Commission. Although this license is less common than others, it offers maximum protection of fair terms for all players and also oversees their personal and financial data. As we already hinted, OnlySpins is not just a sportsbook but also a very well-made online casino. It lets you play popular slots, live casino or even game shows. Naturally, you’ll also find roulette, blackjack, poker, and other card games. The sportsbook itself offers a huge selection of betting opportunities, including both pre-match and live betting.

2) Payout

Payout (also called payout rate) expresses the percentage return on a bettor’s stake. The closer it is to 100%, the better for the bettor. The difference between 100% and the actual payout is the margin the sportsbook charges on the given market. Payout, and therefore margin, will be different across markets, i.e., depending on the sport, competition, bet type, and pre-match/live. Because information about an average payout tells a bettor little, we selected several specific markets to demonstrate the payout you can roughly expect. We chose popular sports (football, ice hockey, basketball, and tennis) and markets (match winner, handicap, winner including OT, over/under, Asian handicap, draw no bet). We intentionally contrasted competitions (tournaments) so you can see the difference between matches with large betting volume and the opposite.

I started gaining experience in sports betting through my work in the customer support of a foreign bookmaker. It didn't take long before I started betting actively myself. This has continued to this day. Besides thematic articles, I look for interesting bonus offers and valuable odds for you. You can find all articles here.
