Osiris Casino No Deposit Bonus Codes

Anyone searching for “Osiris Casino no deposit bonus codes” should know one key fact right away: Osiris Casino closed on March 31, 2025, and it is no longer accepting new players. That means there are no current no deposit bonus codes to claim, no active welcome package to unlock, and no new player promotions available at the site.

This matters because older bonus pages and forum posts can still show up in Google, even when the offers are dead. In Osiris Casino’s case, many of the promo codes people still search for were part of expired campaigns that ended before the casino shut down.

The Big Update: Osiris Casino Is Closed

Osiris Casino previously operated under Conan Gaming Limited and held a Malta Gaming Authority license. However, the brand ceased operations in 2025, and several casino review sites later flagged it for unfair bonus terms.

For players in the US, that makes this less of a bonus hunt and more of a warning. If you see a page claiming that Osiris Casino still has an active no deposit bonus code, that information is outdated.

Historical No Deposit Bonus Codes That Once Circulated

Before the casino closed, Osiris Casino occasionally ran free chip and free spins promotions that required a code at the cashier. These offers were temporary, and none of them are active now, but they are the codes most often tied to search queries today.

Among the better-known historical offers were:

• “GRATIS50” for a $50 free chip
• “10GRATIS” for a €10 free chip
• Free spins promotions on Thunder Zeus, usually tied to a code-based campaign

These promotions were typically marketed as no deposit deals, but they came with substantial strings attached. In most cases, the wagering requirement was 45x the bonus, and gameplay was usually limited to slots.

Why These Bonus Codes Were Never as Good as They Looked

On paper, a no deposit bonus sounds appealing because it lets players try a casino without risking their own money. The catch at Osiris Casino was the heavy playthrough requirement and the restrictive terms attached to bonus funds.

A 45x wagering requirement on a free chip is steep by any standard. For example, a $50 chip with 45x wagering means a player would need to generate $2,250 in qualifying wagers before becoming eligible to cash out bonus winnings, and that is assuming the games played counted fully toward the requirement.

Reports also pointed to tight rules around withdrawals, excluded games, and bonus cancellation. If a withdrawal request was submitted before the playthrough was complete, the active bonus and related perks could be voided.

The Welcome Offer Also Had Tough Terms

Osiris Casino’s old welcome package did not require a bonus code, but it is still worth mentioning because many players searching for no deposit codes also land on pages discussing its signup offer.

The first deposit promotion was advertised as 300% up to €900 plus 20 free spins. Additional deposit bonuses reportedly followed, including a 350% offer with 30 free spins and a 400% offer with 40 free spins.

That sounds aggressive, but the terms were difficult. The wagering was generally listed at 45x the bonus plus deposit, which is much harsher than what many players expect from a competitive online casino bonus. If you want a point of comparison, standard terms at more reputable sites often fall closer to 20x to 35x, depending on the promotion.

Why Osiris Casino Drew Criticism

The biggest issue was not the size of the promotions. It was the gap between the marketing and the actual value once the terms were applied.

Multiple review platforms and watchdog sites criticized Osiris Casino for unfair bonus conditions. Complaints centered on high wagering, limited game contribution, strict withdrawal rules, and terms that made it difficult for players to convert bonus wins into cash.

That context matters when discussing no deposit bonus codes. A free chip is only useful if the terms give players a realistic shot at cashing out. In this case, many reviewers argued the promotions did not meet that standard.

Game Selection Players Once Used for Bonus Play

Back when the site was active, slot play was the main way to work through wagering requirements. The casino carried games from providers like Betsoft and NetEnt, with titles ranging from classic-style slots to Egyptian and sports-themed games.

Examples from the old lobby included Book of Helios Slots, Jumbo Joker Slots, Tiger's Claw Slots, Football: Champions Cup Slots, Lost Mystery Chests Slots, and Primal Wilderness Slots.

Live dealer games and table games reportedly counted at much lower contribution rates, around 10% in some cases. That made slots the default path for bonus clearing, but it also increased variance and made those playthrough targets harder to manage.

Payment Methods and Currencies Once Listed

Historically, Osiris Casino advertised a broad range of payment options, including Visa, MasterCard, Skrill, Neteller, PaySafeCard, bank wire transfer, Bitcoin, and Western Union. It also listed support for currencies such as USD, CAD, EUR, GBP, AUD, Bitcoin, and ZAR.

That broad cashier menu may still appear on archived pages, but it is no longer relevant for active play because the casino is shut down. Support details that once existed, including email and phone contacts, should also be treated as historical only.

What US Players Should Do Instead

If you are in the United States and searching for no deposit casino bonus codes, Osiris Casino should be crossed off your list. The site is closed, and even before closure, its bonus terms drew serious criticism.

A better move is to focus on licensed, regulated operators in your state and read the fine print before claiming any promotion. Pay close attention to wagering requirements, max cashout rules, eligible games, minimum deposit terms, and whether the bonus is automatic or code-based.

A no deposit bonus can still be useful, but only when the offer is current, the operator is reputable, and the terms are clear enough that you know exactly what you are getting.

The Bottom Line on Osiris Casino Bonus Codes

There are no active Osiris Casino no deposit bonus codes in 2026 because the casino has been closed since March 31, 2025. Codes like “GRATIS50” and “10GRATIS” belong to expired promotions and should be viewed as part of the brand’s history, not as live offers.

If you came here looking for a working code, the short answer is that there is none. The more important takeaway is that even when Osiris Casino was operating, its bonus structure raised enough red flags that players had good reason to be cautious.
