Bitsler review: licence, withdrawals, complaints and verdict

Image: Bitsler site icon

Bitsler was a dice-first crypto casino and sportsbook that launched in 2015, and as of 9 November 2026 its website shows only a notice saying it is closing and no longer accepting bets. We rate its record Mixed, and we have marked the page closed. The figures below come from pages we read; we have not played there.

• Launched: 2015, according to AskGamblers and Blockonomi.
• Operator: Oyine N.V., a Curaçao company (company number 144430 according to one review site), per AskGamblers and Blockonomi.
• Licence: a Curaçao licence per AskGamblers (Curaçao Gaming Authority); Blockonomi quotes an older eGaming licence number. We could not check a register.
• Coins: BTC, BCH, ETH, USDT, DOGE, LTC, XRP, TRX, DASH, BNB, ADA, USDC and DAI in our notes; reviews put the total at 20 to 30 or more.
• KYC: email and date of birth to sign up; documents requested for withdrawals and limits, and the source of most complaints.
• Games: in-house provably fair games such as dice, plus slots, table games, live dealer and a sportsbook.
• Status: closing. Its notice asks users to withdraw by 11 October and says accounts close on 12 October.
• Our rating: Mixed

We listed Bitsler under Bitcoin casinos, Ethereum casinos, USDT and stablecoin casinos, altcoin casinos, crypto slots casinos and provably fair and crash casinos. The wider section is at Crypto Casinos.

A 2015 provably fair dice site with strong player scores and fast payouts alongside repeated KYC holds; its own website now says it is closing, with no reason given, so this is a record rather than a recommendation.

We rate crypto casinos from public sources only: the licence and what it covers, who owns it, what players report about withdrawals and complaints, how clear its terms are and how long it has been trading. Last reviewed 9 November 2026. How we rate crypto casinos.

The first thing to know is that the site is shutting. On 9 November 2026, bitsler.com loaded a single page titled "Bitsler is closing" which said Bitsler is closing and no longer accepting bets, asked users to withdraw their balance by 11 October, said accounts would be permanently closed on 12 October, and told anyone with a balance left after closure to email its support address before the end of 31 October to claim it. The page gave no year and no reason, and named no operator.

The year is not on the notice, but the site was serving it in November 2026, and Trustpilot reviewers wrote about a shutdown in September and October 2026. On 24 September a reviewer said they were shutting down and that balances too small to withdraw would be lost. On 26 September another wrote that the site had shut down. On 17 October a reviewer alleged they were exit-scamming and refusing to pay out. Those are allegations from reviewers, not findings, and Trustpilot does not verify them.

We found no reply from Bitsler on Trustpilot addressing the closure, no statement from a regulator, and no explanation for the closure in the sources we read. Anyone who still holds a balance and missed the 31 October claim date should treat that as an unresolved question for the support email shown on the notice, and should not rely on us to say what the outcome will be.

Do not confuse it with Bitsler.io, the US sweepstakes site under the same brand. Sweepsy reported on 5 November 2025 that Bitsler.io would close on 1 December 2025, with redemptions until that date and email support through 31 December. That was a separate, earlier closure.

Bitsler began in 2015 as a provably fair dice site, according to AskGamblers and Blockonomi, and grew into a casino and sportsbook. Blockonomi and AskGamblers both name Oyine N.V. as the operator, and a review on a crypto site gives its Curaçao company number as 144430. We found no public information about who owns Oyine N.V.

In May 2026 GNcrypto reported that Bitsler announced near-instant on-chain Bitcoin withdrawals, adding Ethereum and USDT support, a 200% sign-up deposit match up to $2,000 with 500 free cash spins, and a wallet-connect option that it said reduced the personal data it collected. That was the operator's own announcement, as reported, and it came about five months before the closing notice.

Dice was the core. GNcrypto reports Bitsler describing Dice and Keno as provably fair with published cryptographic proofs, and Blockonomi says 16 Bitsler-developed games run on provably fair technology without explaining how players verify results. A review on a crypto blog lists Dice, Crash and Mines as the instant games.

The wider library varied by source. Blockonomi claims over 3,000 casino games including 43 table games and 32 live dealer tables, plus a sportsbook with more than 40 sports and esports. AskGamblers says slots come from more than 50 providers, with about 100 table games and over 60 live dealer games, and lists RTP as not stated and independent RNG testing as "No". Those are review-site counts, and the games are no longer available to check.

Withdrawals were crypto and e-wallet only. AskGamblers lists crypto withdrawals at 0 to 1 hour, a minimum of about $10 and no stated limits, with fees applying. Blockonomi, an affiliate review, claimed an average of 5 to 10 minutes and said sign-up needed only an email address and date of birth, with documents asked for to raise limits.

Trustpilot reviewers praise fast deposits and withdrawals, and also describe the other side. Several say withdrawals sat pending for days with little explanation, often tied to KYC or verification. In one reply about a KYC delay, Bitsler said a third-party provider needed more time to review Turkish-language documents and acknowledged that its communication about timelines needed improvement.

AskGamblers records the same pattern from its complaints: withdrawals of $50 to $1,500 held for days or weeks while KYC, address proof or "security checks" were requested, with support reportedly unresponsive. One player reported a $3,800 deposit blocked after a few bets, with Bitsler alleging multiple accounts, which the player disputes; Trustpilot has a reviewer making the same complaint.

AskGamblers lists Bitsler as licensed by the Curaçao Gaming Authority under Oyine N.V. Blockonomi quotes an older Curaçao eGaming number, 8048/JAZ, as of its November 2025 update. We could not open either register, so we cannot say which licence applied at closure or what it covered. Curaçao licences are offshore licences with limited player-dispute routes.

AskGamblers also lists limited responsible gambling tools: self-exclusion and a self-assessment test, with no deposit, loss, session or cool-off limits. We found no proof of reserves. The provably fair label covers the in-house games; it lets a player check that a result matches a seed, and does not say anything about whether a withdrawal will be paid.

Bitsler ran XP-based bonuses, VIP tiers, weekly and monthly coupons, contests and chat games, according to Trustpilot reviewers. Blockonomi's description of the welcome offer contradicts itself (a 200% match up to $200 in one place, 100% up to $700 in another), and GNcrypto reports the 200% up to $2,000 offer announced in May 2026, so we do not list a definitive offer.

Bonus and VIP disputes appear in the complaints. Reviewers report withheld or unpaid bonuses and a dispute where a Platinum 5 VIP blamed a platform bug; Bitsler replied that it was not caused by its platform but by a configuration issue on the player's device. One reviewer who described themselves as a VIP with large wagering gave one star on 17 October 2026.

AskGamblers lists 21 complaints, of which 19 are marked resolved, with a two-day average response and a seven-day average duration. It also warns that several complaints marked resolved describe holds that were still in place. The cases it highlights include a roughly $10,000-wagering account still restricted after nearly two months and the $3,800 multiple-account dispute above. The latest complaints on the page date from late April and early May 2026.

On Trustpilot, Bitsler scored 3.3 from 390 reviews on 9 November 2026, with 74% five-star and 15% one-star. Bitsler replied to 15% of negative reviews, typically within two weeks, and some replies were posted in batches. Complaint themes were withdrawal delays and holds, account restrictions, withheld bonuses, claims of rigged odds or "burned" bets in provably fair games, and the shutdown claims described above. The fairness claims are unverified opinions and we found no audit that supports or refutes them.

We found no regulator action against Bitsler in the sources we read.

The good

• Operated from 2015 to 2026, a long record for a crypto casino.
• AskGamblers player rating of 8.5 out of 10 from 119 reviews, with 19 of 21 complaints marked resolved.
• Provably fair in-house games and fast payouts praised by reviewers.
• A published closing notice with a claim route for missed balances.

The bad

• Withdrawals held for days or weeks under KYC or "security checks", by AskGamblers and Trustpilot accounts.
• No reason given for the closure, and unverified exit-scam allegations from reviewers.
• Limited responsible gambling tools and no independent RNG testing listed.
• Operator ownership and licence not verifiable by us.

Our verdict. Bitsler's record before the closure was mixed: strong player scores and fast payouts alongside repeated verification holds. The closure is the open question. A site that posts a deadline and a way to claim late balances is behaving differently from one that vanishes, and we found no evidence of non-payment. But we also found no explanation, and the deadlines have passed. We rate it Mixed and treat this page as a record, not a recommendation.

Almost no crypto casino holds a UK Gambling Commission licence, and a site must hold one to offer gambling to people in Great Britain. We found no UKGC licence for Bitsler and could not confirm whether it accepted UK players. Players on such sites were outside GAMSTOP and UKGC protections, and we do not suggest ways around any country block.

Is Bitsler closing?

Its own website says so. On 9 November 2026, bitsler.com showed a notice saying it is closing and no longer accepting bets, asking users to withdraw by 11 October and closing accounts on 12 October. It gave no reason, and we found no regulator statement about the closure.

Can I still get money from my Bitsler account?

The notice said anyone with a balance after closure could email its support address before the end of 31 October to claim it. That date has passed as of 9 November 2026, and we found no update. We cannot say what happens to late claims, so contact the support address shown on the site.

Is Bitsler a scam?

We found no regulator, court or police finding that it is. Some Trustpilot reviewers in September and October 2026 allege exit-scamming, but those are unverified opinions, and the site posted a closing notice with a claim route. Before closing, AskGamblers showed 19 of 21 complaints marked resolved.

Who owned Bitsler and was it licensed?

AskGamblers and Blockonomi name Oyine N.V., a Curaçao company, as operator, licensed in Curaçao. We could not check a licence register, and we found no public information about who owns the company. Curaçao licences are offshore licences with limited dispute routes for players.

Is Bitsler.io the same as Bitsler.com?

No. Bitsler.io was the US sweepstakes site under the same brand, and Sweepsy reported it would close on 1 December 2025. Bitsler.com is the crypto casino whose notice now says it is closing. They closed at different times, and the second closure is the one covered in this review.

What was Bitsler known for?

Dice. It launched in 2015 as a provably fair dice site and grew into a casino and sportsbook with 20 or more coins. Reviewers praised fast payouts and an active chat community, while complaints focused on withdrawals held for KYC and security checks.
