OscarSpin Casino is run by Terdersoft B.V., licensed in Curaçao, not Hollycorn N.V. as some sites have claimed. Its real sisters are Coolzino, Billionairespin, Savaspin and Roman Casino, all from the same company. If OscarSpin doesn’t suit you, this is the group worth trying instead.
How the four sisters compare
| Brand | Launched | Providers | Best for |
|---|---|---|---|
| Coolzino | 2024 | Around 73 | An established name with a solid studio mix |
| Billionairespin | 2025 | Around 79 | The closest match in age to OscarSpin |
| Savaspin | 2024 | Around 110 | The widest game selection |
| Roman Casino | 2024 | Around 80 | A varied studio mix, though verification is slower |
🧭 Getting the operator right
A lot of sites listing OscarSpin’s sister casinos have named the wrong company. OscarSpin is not part of the Hollycorn N.V. network, which runs separate brands like ZotaBet and SkyCrown. It’s run by Terdersoft B.V., a smaller Curaçao operator that launched OscarSpin in 2025 alongside a handful of other casinos. That mix-up matters, because it means a lot of “sister site” lists for OscarSpin online are simply wrong, and following one could send you looking for promotions or account crossover that doesn’t actually exist between brands. Here’s what the real family looks like, checked against the casinos’ own ownership details rather than copied from another list.
Coolzino Casino
Coolzino launched in 2024 and is one of the more established names Terdersoft runs. It carries around 73 providers, including NetEnt, Pragmatic Play, Nolimit City, Playtech, Yggdrasil Gaming and BGaming, giving you a decent split between big-name slots and smaller studios worth trying if you want something different. Payments cover cards, e-wallets like Skrill and PaysafeCard, bank transfer, and crypto including Bitcoin, Ethereum, Litecoin and Tether. Standard withdrawals are processed within 24 hours, though bank transfers can take up to five extra banking days to actually land. Verification here has drawn some complaints about tight document deadlines, so get your ID and proof of address in as soon as you sign up.
Billionairespin Casino
Billionairespin is the newest of the group, launched in 2025 like OscarSpin itself, so the two share a similar age and feel. It runs a smaller library of around 79 providers, including Pragmatic Play, NetEnt, Evolution Gaming, Nolimit City and Playtech, with the usual live dealer tables for blackjack, roulette and baccarat. Payment options are a little slimmer than at Coolzino, covering Neteller, Skrill, cards, bank transfer and a handful of cryptocurrencies including Bitcoin, Ethereum and Litecoin. Withdrawals can take up to 24 hours to process and up to five banking days to clear if you use a bank transfer, so crypto is the better choice if speed matters. Daily withdrawal limits sit around €1,000, rising to €10,000 a month.
Savaspin Casino
Savaspin launched in 2024 and carries one of the bigger libraries in the group, at around 110 providers, including NetEnt, Pragmatic Play, Evolution Gaming and Playtech. That’s a good spread if you like a large pool of slots to pick through rather than a small curated list. Payment options include Skrill, PaysafeCard, cards, bank transfer and a wide crypto list covering Litecoin, Ripple, Ethereum, Tether, Tron and Dogecoin alongside Bitcoin. As with its sisters, standard processing takes up to 24 hours, with bank transfers adding several more days. Verification has been described by some players as lengthy and demanding, so don’t leave it until you want to cash out a big win.
Roman Casino
Roman Casino has been running since 2024 and carries around 80 providers, including NetEnt, Novomatic, Nolimit City, Playtech, Evolution Gaming and Pragmatic Play, giving it one of the more varied mixes in the group between big studios and smaller ones. Payments are simpler here, with cards, bank transfer and a solid crypto list including Bitcoin, Bitcoin Cash, Ethereum, Tether, Tron, Litecoin and Dogecoin. Some players have reported very long verification delays, including document rejections that dragged on for weeks, so this is the sister to treat with the most caution on that front, even though the game selection itself is solid.
Good to know
- Coolzino carries around 73 providers including NetEnt and Pragmatic Play, an established mix.
- Billionairespin shares OscarSpin’s 2025 launch year, so it feels closest in age.
- Savaspin carries around 110 providers, the widest game selection in the group.
- Crypto withdrawals across the group are usually processed within a day once verified.
Worth checking
- OscarSpin itself is brand new, so there is not much long-term track record yet.
- Roman Casino has had reports of long verification delays, including document rejections.
- Bank transfers are the slowest payment method, often taking most of a week.
- Daily withdrawal limits are low across the group, generally a grand or two.
OscarSpin itself, briefly
OscarSpin launched in 2025 and carries around 70 providers, including Pragmatic Play, NetEnt, Evolution Gaming and Yggdrasil Gaming, with live dealer tables and the usual slot mix you’d expect from a casino this size. It accepts cards, Interac, Google Pay, Apple Pay and crypto including Bitcoin, Ethereum and Litecoin. Standard withdrawals process within a day for e-wallets, while bank transfers can take five to seven days and card withdrawals three to five. Daily withdrawal limits are fairly low across the board in this group, generally a grand or two, so big wins tend to come out over more than one payment. It’s a reasonable enough casino on its own, but being this new means there isn’t much long-term track record to point to yet.
🛡️ Getting verified across the group
All five casinos ask for a photo ID, proof of address at some point, and confirmation of your payment method. Roman Casino and Savaspin have had the most complaints about slow or repeated document requests, while Coolzino and Billionairespin tend to move a bit faster based on player reports. Since this is a newer, smaller operator group than some of the bigger Curaçao names, it’s worth sending your documents in the moment you sign up rather than waiting for a withdrawal to force the issue.

Games worth knowing about
Across the group you’ll see the same core studios again and again: Pragmatic Play, NetEnt, Evolution Gaming and Nolimit City show up at every one of these casinos. Coolzino and Savaspin carry the widest libraries if you want more choice, while Billionairespin and Roman Casino keep things a bit smaller and more curated. Live dealer tables are standard across all four, running blackjack, roulette and baccarat through Evolution Gaming.
💳 Payments, in plain terms
Crypto is the fastest option everywhere in this group, usually processed within a day once you’re verified. Cards and e-wallets are next, with bank transfers the slowest, often taking most of a week once you add the extra banking days on top of the casino’s own processing time. Daily and weekly withdrawal limits are on the low side across the whole group, generally in the €1,000 to €4,000 range, so plan for a big win to arrive in more than one payment. If you want the least hassle, pick one payment method and stick with it across deposits and withdrawals, since switching methods partway through can slow down verification.

Bonuses, in plain terms
Every casino in this group runs a first deposit bonus, usually with free spins attached, plus reload offers after that. The headline numbers change often enough that quoting them here would go stale fast, so check each site directly before you sign up. What actually matters is the wagering requirement and the maximum bet allowed while you’re clearing a bonus. Given how new most of these casinos are, it’s worth reading the terms in full rather than assuming they’ll match what you’re used to at bigger, older sites.
Mobile play
All five sites run fine through a mobile browser, with no app needed on any of them. The layout carries over from desktop cleanly, including live dealer tables, so you won’t lose anything by playing on a phone. As with any newer casino group, it’s worth testing a small deposit first to check how a site performs on your specific device before committing bigger amounts.
🥇 Which one to try
If you want the widest game selection, Coolzino or Savaspin are the better picks, since both carry over 70 providers and give you plenty to work through. If you’d rather stick with a newer casino closer in age to OscarSpin, Billionairespin is the closest match, sharing the same 2025 launch year and a similar feel. Roman Casino has a solid game list too, with a good spread of studios, but its verification track record is the weakest of the four, so go in with realistic expectations and get your documents in early if you pick that one.
For other groups worth comparing, the Dragon Slots sister sites sit under a different Curaçao operator again, while ZotaBet’s real sisters run under Hollycorn N.V. and Jet4Bet’s sisters cover the Stable Tech N.V. group. It’s worth checking any casino’s real operator against a source like sistercasinofinder.com before you sign up, since mix-ups like the one on this page happen more often than you’d think.
