ArbVantage vs Ninjabet: matched betting or sure bets?
Ninjabet (ninja-bet.de) is a German matched betting service; ArbVantage is a sure bet and middle scanner. Both deal with splitting stakes across outcomes, but the edge comes from different places. This page compares the two on public information, works through a free bet and a sure bet with real numbers, and explains what changes if you bet from Austria.
We make ArbVantage, so we are a party to this comparison. Every claim about the other product has a dated source below, and we say where it is ahead.

Two categories: matched betting service and sure bet scanner
Matched betting uses promotions. A bookmaker gives you a free bet or a bonus; you place it and cover the outcome with an opposing bet, traditionally a lay bet on a betting exchange. The edge comes from the value of the offer, not from the odds. According to its website, Ninjabet provides guides to offers, an OddsMatcher that finds suitable pairs of odds, a Dutcher, a bet tracker and further tools, including sure bet, value bet and middles sections.
A sure bet scanner looks for markets where the best odds at different bookmakers add up to less than 100% implied probability. The edge comes from the price difference, with no bonus needed. ArbVantage shows pre-match sure bets and middles, calculates the stakes, and has a calculator for converting free bets with a covering bet at a second bookmaker. Our value bets are coming soon.
Both methods are compared in detail in arbitrage vs matched betting.

Austria: matched betting without an exchange
The classic matched betting guide comes from the UK: place the free bet at a bookmaker, then lay the same outcome on an exchange. According to Betfair's own country help page, the Betfair exchange is not available to customers in Austria or Germany, and Matchbook restricts customers from Austria. We are not aware of a betting exchange with an Austrian state licence. More in betting exchanges.
Without an exchange, you cover the free bet at a second bookmaker instead (back/back, or dutching). That works, but usually keeps a little less of the free bet's value, because you back the other outcomes at bookmaker odds rather than exchange odds. Mathematically it is the same task as a sure bet: spread the stakes so that every outcome returns the same amount.
Two more points for Austria:
- Offers. Which bonuses exist depends on the country. Check whether the offers in a guide apply to customers from Austria.
- Bonus terms. Bookmakers can restrict or cancel bonuses under their terms if they suspect systematic hedging. What such clauses mean is explained in bonus abuse explained.
Worked example: one free bet, one sure bet
You have a €20 free bet, stake not returned. Bookmaker A offers 4.00 on player 1, bookmaker B offers 1.30 on player 2.
Covering stake at B = 20 × (4.00 − 1) ÷ 1.30 = €46.15.
Player 1 wins: the free bet pays €60 and the covering bet loses €46.15. Result: +€13.85.
Player 2 wins: the covering bet returns 46.15 × 1.30 = €60.00, minus the €46.15 stake. Result: +€13.85.
You keep about 69% of the free bet value, but only once per offer.
At a 1.5% margin and €200 in total stakes, €3 is left per sure bet. To make the same €13.85 you would need about 4 to 5 such sure bets, but they can be repeated as long as price differences appear and your accounts are not limited.
Both examples assume every bet is placed at the shown odds and stands. Real results vary and can be negative: odds change, bets get voided and accounts get limited. If a bookmaker passes the Austrian betting fee on to you, include it. The method for free bets is explained in the free bet calculator.
Which one makes sense when
Ninjabet is likely the better fit if you live in Germany, want to work through many new welcome offers and want step-by-step guides to individual promotions. The price is low, and the free tier is enough to try it out.
ArbVantage is likely the better fit if you bet from Austria, have no exchange account, do not want to depend on bonus offers and want to find sure bets and middles at your own bookmakers on an ongoing basis.
To be honest: if your only goal is a few bookmakers' welcome offers, you do not need a sure bet scanner; a free bet calculator is enough. A scanner only makes sense if you want to use price differences regularly over months; the options are compared in best arbitrage betting software. Whether that would cover the cost at your stakes, you can work out in what is a good arbitrage percentage?
Combining both
Many people who start with matched betting move on to sure bets once the welcome offers are used up. The basics are the same: split stakes, check bet slips carefully, manage balances across several accounts and record every bet. For free bets you receive anyway, ArbVantage has its own calculator for the covering bet at a second bookmaker, so you do not need a second subscription for that.
One thing to watch when combining: bookmakers notice both systematic bonus hedging and regular sure bets. Either can lead to limits, and a limited account often stops receiving offers too. More in bookmaker limits.
Frequently asked questions
Does Ninjabet work in Austria?
Partly. The guides and calculators can be used anywhere, but the bookmaker lists on ninja-bet.de are labelled for Germany. Classic hedging on the Betfair exchange is not available to customers in Austria; what remains is a covering bet at a second bookmaker.
What is the difference between sure bets and matched betting?
With sure bets, the edge comes from price differences between bookmakers, without a bonus, and can be repeated until accounts are limited. With matched betting, it comes from the value of free bets and bonuses, which usually apply only once per person.
How much does Ninjabet cost compared with ArbVantage?
According to ninja-bet.de, Ninjabet Premium costs 19.98 euros a month, 99 euros per six months or 149 euros a year, and there is a free tier. ArbVantage costs 97 euros a month after a 14-day trial and is a sure bet scanner, so a different category (as of October 2026).
