Osombet launched in 2025 and made a choice most new casinos avoid: crypto only, no fiat, no exceptions. It is run by OSOM Entertainment Group under an Anjouan licence, and the lobby is bigger than the launch date suggests, with close to 6,800 slots and one in-house title, OSOM Hold and Win, that you cannot play anywhere else.
Here is what the games, the bonus terms, the payment rules and the licence actually look like.
Osombet at a Glance
Deposits and withdrawals run in BTC, ETH, LTC, USDT and TON. Deposits land in minutes. If you want to pay by card or bank transfer, this is not the casino for you, and there is no sign of that changing soon.
There is no app. Everything happens in the browser, and the site was built mobile-first, so a phone session feels the same as a desktop one. Osombet also keeps an active Telegram channel, and a fair number of offers show up there before they reach the main site. Some never reach it at all.
Game Library and Providers
The lobby splits into seven tabs: slots, game shows, crash games, live casino, instant games, table games and virtual sports. Slots dominate. There were 6,748 of them at the time of writing, next to 50 crash games and 39 game shows.
Pragmatic Play supplies the headliners, Gates of Olympus 1000 and Sweet Bonanza among them. Nolimit City covers the high-volatility end with titles like Mental. Booming Games, Red Tiger, NetEnt, Yggdrasil, Habanero, Betsoft and Novomatic fill in from there, and 1spin4win accounts for a large slice of the raw count, which is worth knowing if you open the slots tab and wonder why so many thumbnails are the same red seven.
Two things set the place apart. The first is crash. Aviator leads it, and the section runs on provably fair mechanics, so you can check the outcome of any round yourself rather than take the casino’s word for it. Fifty titles is deep for this category. JetX, Zeppelin, Balloon, Deep Rush and Crash Duel X are all in there.
The second is OSOM Hold and Win. It is exclusive to the site, and new players get free spins on it at registration, which makes it the obvious first stop.
Live tables come almost entirely from Evolution and Ezugi. Blackjack, roulette and baccarat, plus the game show side with Crazy Time, Funky Time and Dream Catcher.

Bonuses and Promotions
The welcome offer is 20 free spins on OSOM Hold and Win, unlocked with the code OSOM-20 on a minimum deposit. Wagering is 20x, the payout caps at 50 USDC, and the whole thing expires after three days. Three days is short. Read the terms before you deposit rather than after.
Ongoing promotions are the stronger side. There is a 20% Aviator bonus every day and a 50% bonus on any deposit made in TON, plus reloads, cashback on losses and a rotating daily and weekly calendar. Telegram members get first look at most of it, including deposit bonuses and free spins that run on a short clock.
The VIP programme goes by “Spin More, Raise Faster”. You climb ranks by playing, and each rank unlocks better bonuses, more cashback and rewards you cannot get otherwise. Missions and tasks speed up the climb.
Payments: Deposits and Withdrawals
Bitcoin, Ethereum, Litecoin, Tether and Toncoin, all as wallet transfers. Deposits credit within minutes. No fiat.
Before a withdrawal goes through, any active bonus has to be fully wagered, and network fees apply depending on the coin you pick. Verification may be requested ahead of a first payout, so get your documents together early rather than at the cashier.
Support and Availability
Live chat runs from 10:00 to 18:00 CET. Email is open around the clock. Play outside those hours and you will wait, and that is the clearest gap in an otherwise tidy operation.
Osombet works from a list of accepted markets rather than a list of banned ones. Canada, Mexico, Argentina, Chile, Peru, Ecuador, Uruguay, Paraguay, Venezuela, Guatemala, Honduras and Haiti are in. So are Norway, Ukraine, Moldova, Serbia, Slovenia, Albania, North Macedonia and Bosnia and Herzegovina. Kazakhstan, Kyrgyzstan and Uzbekistan cover Central Asia, and India, Japan, Vietnam, Cambodia and Laos round it out. Anywhere else, check the terms before you register.
Security, Licensing, and Responsible Gambling
The licence is ALSI-202410027-FI1, issued by the Government of the Autonomous Island of Anjouan to OSOM Entertainment Group, company number 20291, registered in Hamchako, Mutsamudu. Payments run through Osomspin Ltd in Limassol, Cyprus, acting as an agent under a separate agreement.
Be clear about what that means. Anjouan is offshore and oversight is lighter than under the MGA or the UKGC. Standard for crypto casinos, but it belongs in your decision.
The site uses SSL, publishes a KYC policy and offers responsible gaming tools including self-exclusion, deposit limits and player verification. Provably fair mechanics in the crash section let you audit single results yourself. A standard RNG certificate does not give you that, but it does cover the wider library in a way provably fair cannot, so treat them as separate things rather than one replacing the other.

Final Verdict
Osombet suits crypto players who want fast payouts, a serious crash section and a promo calendar that actually moves, and who can live with an offshore licence. The exclusive slot and the daily Aviator bonus give it a shape most new casinos lack. If you need fiat or tier-one regulation, look elsewhere for now.
If it fits, create an account at Osombet and claim your welcome free spins on OSOM Hold and Win. Read the bonus terms and wagering requirements in full first.
