Marlin review
Our testers ran a funded Marlin account for three months — 81 settled bets, six timed withdrawals and twelve support queries. This is what we found.
The verdict
Our verdict on Marlin
Marlin is the bookmaker we would open first if we could only keep one account. It is not the sharpest price on any given market, but it is the only product in this guide that scores above 8.8 in five of our six categories. Across forty markets a month it averages 4.1%, third of fifteen, and our six test withdrawals cleared in 2 — 4 hrs. Its strongest categories are usability and payments; the weakest is promotions, at 8.8.
What we liked

What we didn't

Who it suits: bettors who put usability and payments first, and who bet in-play. If the last half-point of price matters more than anything else, read our Kestrel review instead.

The headline and, more usefully, the eight conditions attached to it.
Our reading: the qualifying odds are low and the value is paid without wagering, which puts this among the better opening offers in the guide. The seven-day expiry is the catch — plan to use the value in the first week.

EsportsOdds & margins
How the prices measure up
We price the same forty markets every month across all fifteen bookmakers. The margin is the built-in edge — lower is better for you.
Across all forty markets Marlin averages 4.1% — third of fifteen, roughly 0.7 points behind Kestrel. On a £50 stake that difference is around 35p a bet: real, but smaller than most bettors assume.
