Withdrawals are the problem
1win is a crypto and fiat casino and sportsbook, and the thing to know before anything else is how its players say cashing out goes. It has 1.8 on Trustpilot from 181 reviews, and the recent 1-star reviews describe the same few things. A withdrawal shows as requested, then sits for days or flips to cancelled. One player asked for R400 (South African rand) and was still waiting 36 hours later. Another says the account was blocked right after passing KYC, the identity check where you send ID and proof of address. Others describe support that answers with automated messages (one review) or keeps asking for more screenshots and documents. One of the same reviews says deposits went through without trouble.
That is why I would not deposit. 18+ only, and only money you can afford to lose.
What 1win is
1win has been running since 2016 and holds a Curaçao licence. Curaçao is an offshore licence, with far less player protection than a UK or EU licence, and it gives you no regulator in your own country to complain to. It sells slots, live casino tables, a sportsbook, crash games and virtual sports. There is no CS2 skin deposit or withdrawal. You fund it with crypto, a bank card, Apple Pay or Google Pay, and you withdraw by crypto or bank transfer.
It is big. About 3.98 million visits in August 2026, up from about 2 million in March, with a peak of about 4.5 million in July. South Africa sends about 21% of visitors, Argentina and Brazil about 8% each. Visitors stay a long time, about 9 pages and 12 minutes a visit, which fits a site people play on rather than check once.
We couldn't read its terms
1win's site, including its rules pages, returned a 403 error to us when we checked on 24 and 25 October 2026, and the Wayback Machine's copies of those pages are empty app shells with no text. So we can't quote the operating company, the licence number, the list of banned countries, the withdrawal limits or the bonus wagering rules. For a site this size, that is a problem in itself: you should be able to read who you are dealing with before you deposit.
Our records list 1win as restricted in the US, the UK and much of Europe. Check the terms on the site yourself before signing up, because playing from a country it bars is the easiest way to get a withdrawal refused.
Colombia says it is not authorised
Colombia's gambling regulator, Coljuegos, says 1win is not authorised there. In May 2024 it ordered a "Viva 1win Partners" event for influencers in Medellín to be called off, and 1win cancelled it. In a bulletin dated 21 February 2025, Coljuegos said it had blocked 141 websites tied to the 1Win brand, out of 409 illegal betting sites it took down across 1Win, 1XBET, BBRBET and Pinnacle, and warned that players on blocked sites can lose their deposits.
141 domains also tells you how 1win reaches players: through many mirror and lookalike addresses. Searching for 1win turns up sites that use its name and push their own promo codes. Make sure the site you deposit on is really 1win, and remember that a mirror is not a way around your own country's rules.
What the on-chain data shows
There is a counterweight to the complaints. On-chain data covering about 94% of 1win's crypto flow shows $81.4 million in crypto deposits and $84.9 million in crypto withdrawals over the latest 30 days, so about $3.5 million more went out than came in. It has about $9.8 million in tracked treasury wallets and around 47,000 depositors, which puts it 10th of the 34 casinos in our on-chain data.
So 1win does pay crypto out, at scale. What the chain can't see is card and bank withdrawals, and the complaint with a stated amount is in rand. If you use 1win anyway, crypto is the route the data can at least confirm.
The median crypto deposit is $20.07, while the average is $494. Most depositors put in small amounts, and a smaller group deposits a lot.

What the games cost
House edge, or for sports the hold, is the share of what you bet that the site keeps over time. For 1win's sportsbook, the on-chain estimate is a 5.5% hold, so about $5.50 lost for every $100 bet over many bets. That is lower than the roughly 7% estimated for Stake's sportsbook, so the betting itself is not unusually expensive.
For the casino side we have no measured edge, and our records show no provably fair claim, the system that lets you check a result wasn't changed after you bet. If you are used to the 1% in-house games on sites like Stake, 1win's crash games give you nothing equivalent to check.
| Product | What we have | Loss per $100 bet over time |
|---|---|---|
| Sportsbook | 5.5% estimated hold (on-chain) | about $5.50 |
| Crash and casino games | no measured edge, no provably fair claim on record | unknown |
The cashback and the Betrefs link
1win advertises cashback of up to 30%. Cashback means part of your losses comes back to you. "Up to" is the ceiling, and since we couldn't read the terms we can't tell you which games count, how losses are measured or whether the cashback must be wagered before you can withdraw it. There is no Betrefs code for 1win. If you sign up through our link, Betrefs may earn a commission, and as far as our data goes you get 1win's own offers and nothing extra.
Tanzanite's checklist
Tanzanite, a crypto casino data site, rates casinos on a checklist of five areas: provably fair games, responsible gambling tools, customer support, published RTPs, and operations (proof of funds and six months running). It doesn't certify 1win. On its 1win page, checked 29 October 2026, 1win missed the provably fair check because players have no client seed to influence results, offers no wager or loss limits, missed the support checks for resolving issues within an hour and for quality answers, and doesn't clearly publish RTPs. Proof of funds wasn't assessed.
If you sign up anyway
Do the KYC check before you deposit much. A block after KYC is one of the complaints, and it is better to find that out with little money on the account. Make a small first withdrawal, in crypto, before trusting it with more. Keep screenshots of every withdrawal request. Set a deposit limit and stick to it.
