21Bit sister sites are Spin Samurai, Slotozen, Crusino, BitKingz, Casinonic and LevelUp Casino. All seven are operated by Novatrix SRL, registered in Costa Rica under number 3-102-893958, on Tobique Gaming Commission licence 0000002.
21Bit takes more currencies than any brand covered on this site – fifteen in fiat alone. Its withdrawal ceilings are the tightest in the group, matched only by Spin Samurai. Six of the seven publish one; only Casinonic does not.
💰 What the seven publish about withdrawals
Every one of these documents carries a line saying the maximum varies by payment method and appears during the withdrawal request. Six of them then print hard numbers further down anyway.
| 🎲 Brand | 📅 Daily | 📆 Weekly | 📇 Monthly | 💳 Minimum | 🕐 Dormancy fee |
|---|---|---|---|---|---|
| Spin Samurai | €1,000 | €5,000 | €15,000 | €20 | €25 a month |
| 21Bit | €1,000 | €5,000 | €15,000 | €20 | €25 a month |
| BitKingz | €2,500 | €5,000 | €20,000 | €20 | €20 a month |
| LevelUp Casino | €3,000 | €7,500 | €15,000 | €10 | €20 a month |
| Slotozen | €5,000 | €10,000 | €20,000 | €20 | €20 a month |
| Crusino | €5,000 | €10,000 | €20,000 | €20 | €20 a month |
| Casinonic | None published | – | – | €20 | €25 a month |
21Bit and Spin Samurai release the least in a day of the six that publish a figure – a fifth of what Slotozen and Crusino allow, on the same licence and the same cashier. Casinonic is the only one of the seven that publishes no ceiling at all, which sounds generous and is the opposite: there is no figure to plan against.
🏢 Who runs 21Bit
Clause 1.1 names Novatrix SRL, registered under the laws of Costa Rica, registration number 3-102-893958, registered at Cartago, Oreamuno, Potrero Cerrado, Cartago, 30703, operating under licence number 0000002 issued by the Tobique Gaming Commission.
The brand redirects to 21bit12.com. Numbered domains like that are how this group handles being blocked in a market: the licence and the company stay the same, the address changes.
BitKingz, Casinonic and LevelUp Casino carried an Anjouan Gaming Commission licence until recently. All seven now name the same Tobique number, checked against each brand’s own terms in August 2026. The Dama N.V. page covers how Novatrix ended up with this many brands. An eighth brand, Syndicate, names the same company and the same licence in the footer of syndicate.casino. It publishes no current currency list, restricted-country list or withdrawal terms, so it sits outside the comparisons on this page.
💵 Fifteen fiat currencies
EUR, USD, AUD, CAD, NZD, PLN, NOK, ZAR, VND, PHP, IDR, MYR, THB, KRW and CLP. Crypto is BTC, BCH, ETH, LTC, DOGE, USDT, XRP, ADA, TRX and BNB.
Against its sisters that is the widest list in the group. Casinonic runs six fiat currencies and five coins. Slotozen and LevelUp run eight fiat each.
The Vietnamese dong, Philippine peso, Indonesian rupiah, Malaysian ringgit, Thai baht, Korean won and Chilean peso say plainly where 21Bit does its business, and none of those markets is in Europe.
🌎 Who 21Bit turns away
The restricted list is the longest of the seven. It names the United States and its territories – Guam, Hawaii, Puerto Rico, American Samoa, the Northern Mariana Islands and the Virgin Islands – along with the United Kingdom, the Netherlands, Belgium, Brazil, Bulgaria, Cyprus, Estonia, Greece, Latvia, Lithuania, Malta, Poland, Romania, Russia, Ukraine, Georgia, Gibraltar, Guernsey, Jersey, Israel, Japan, China, Bahrain and the sanctioned jurisdictions.
Canada is blocked only in New Brunswick and Ontario. The rest of the country can play.
Sweden can register and deposit but is excluded from every bonus, promotion, VIP programme and loyalty exchange. That clause is word-identical across all seven brands.
⚠️ The dormancy clause
After twelve consecutive months with no login and no gameplay, 21Bit charges €25 a month against the remaining balance, and keeps charging until the balance reaches zero or the account is reactivated. If the balance is under €25, the whole balance goes.
Slotozen and LevelUp charge €20 for the same thing. Casinonic charges €25. It is the one term in these documents that costs money for doing nothing.
🎯 Who 21Bit suits
- ✅ Players in South East Asia and Latin America. THB, PHP, MYR, IDR, VND, KRW and CLP accounts, which almost nothing else on this site offers.
- ✅ Anyone holding ADA, TRX or BNB. Casinonic takes none of the three.
- ❌ Anyone planning a large withdrawal. €1,000 a day is the tightest published daily limit of the seven. Slotozen and Crusino release five times that.
- ❌ Anyone likely to leave an account idle. €25 a month after a year of inactivity.
