Market maths · Call of Duty Example odds
Example odds for OpTic Texas vs Atlanta FaZe. Put the same match side by side at Boomerang-bet and another bookmaker: the margin under each card is the price of the bet.
Who wins the series. Call of Duty League matches are best of five maps across the league's game modes.
| Outcome | Odds | Probability |
|---|---|---|
| OpTic Texas | 1.60 | 62.5% |
| Atlanta FaZe | 2.30 | 43.5% |
| Sum | 106.0% | |
| Margin | 5.6% |
So what: the cheapest market on most cards.
OpTic Texas −1.5 must win by two maps or more (3–0 or 3–1). Atlanta FaZe +1.5 wins if they take at least two maps.
| Outcome | Odds | Probability |
|---|---|---|
| OpTic Texas −1.5 | 2.10 | 47.6% |
| Atlanta FaZe +1.5 | 1.68 | 59.5% |
| Sum | 107.1% | |
| Margin | 6.7% |
So what: in a best of five the handicap line is far more even than in a BO3.
Over 3.5 if the series goes to four or five maps.
| Outcome | Odds | Probability |
|---|---|---|
| Over 3.5 | 1.62 | 61.7% |
| Under 3.5 | 2.20 | 45.5% |
| Sum | 107.2% | |
| Margin | 6.7% |
So what: a 3–0 sweep is the only way under wins.
Who wins the first map only.
| Outcome | Odds | Probability |
|---|---|---|
| OpTic Texas | 1.72 | 58.1% |
| Atlanta FaZe | 2.05 | 48.8% |
| Sum | 106.9% | |
| Margin | 6.5% |
So what: mode strength matters more here than the overall form.

Bonus maths LiveExample data
Boomerang-bet's wagering terms are not in our data, so this uses example sports terms: a $100 bonus, 10x wagering, minimum odds 1.80, at a 6% margin.
Bonus $100 · 10x turnover · singles at odds 1.80+
Turnover costs the margin on what you bet: 10 × $100 = $1,000, and 6.0% of that is $60.
What it means: with singles on low-margin markets such as match winner, the expected cost of wagering stays well below the bonus. Accumulators multiply the margin.
Pros and cons
Who it suits
It is the one title it is tagged for here.
Trustly, Sofort, BLIK and Przelewy24 are listed.
None of these are tagged for Boomerang-bet on this site.
Both are restricted in our data.
Our take: Boomerang-bet is a casino-led brand with a sportsbook on the side. For Call of Duty it can work; for the big esports titles a bookmaker built around esports will give you more markets to compare.
Our provider data lists Curacao. A Curaçao licence gives less player protection than UK or EU regulators, so read the withdrawal terms before you deposit and check the licence number in the site footer.
No. Our data lists the UK and the US among 27 restricted countries. Using a VPN to get around a restriction usually breaks the terms and can void winnings. See esports betting by country for the legal position where you live.
On this site Boomerang-bet is listed for Call of Duty, and for 1 tournament pages. The live list on this page links to each one. Market depth varies by game, so open a Call of Duty match before you deposit and see how many markets it carries.
For Call of Duty it can be. For other esports our tagging shows nothing, so an esports-first bookmaker is the safer start. Check the esports menu on the site before you deposit.
The offer in our data is a €500 bonus with 200 free spins, which reads as a casino package. The wagering terms are not in our data. Check whether a separate sports offer exists and whether esports bets count. 18+, T&Cs apply.
Our data lists 41 deposit methods and 13 withdrawal methods, crypto included. The table on this page groups them by type. Check the cashier from your country: the list there is the one that applies.
