Osiris Casino No Deposit Bonus Codes

Osiris Casino was once a recognizable name in the offshore online gambling world, attracting players with generous-looking welcome packages and a rotating selection of no deposit bonus codes. However, the casino permanently closed its doors on March 31, 2025, and is no longer accepting new players. Before it shut down, it had already been blacklisted by several respected industry watchdogs for unfair bonus terms - a detail that matters a great deal if you're researching this brand for the first time.

This article covers what Osiris Casino's bonus structure looked like while it was active, including its no deposit offers, welcome package, and the key terms players needed to watch out for.

What Was Osiris Casino and Who Ran It?

Osiris Casino was operated by Conan Gaming Limited and held a license from the Malta Gaming Authority. It supported multiple currencies including United States Dollars, Euros, British Pounds, Australian Dollars, Canadian Dollars, South African Rand, and Bitcoin. The casino ran games from a wide roster of software providers, including Betsoft and Net Entertainment, alongside titles from Booming Games, Play'n GO, Wazdan, NextGen Gaming, and several others.

Payment options were extensive on paper, covering everything from Visa and Mastercard to Skrill, Neteller, Bitcoin, PaySafeCard, and Bank Wire Transfer. Despite this range of features, the platform's reputation suffered significantly due to its bonus policies, which we'll get into below.

The No Deposit Bonus Codes Osiris Casino Offered

Osiris Casino did periodically offer no deposit free chip bonuses that players could claim by entering a code at the casino cashier. These promotions were time-limited and are no longer active, but here's what they looked like when they were available.

One of the more notable offers was a $50 free chip available through the bonus code GRATIS50. This gave players a small bankroll to explore the casino without making a deposit. A smaller version also existed - a €10 free chip tied to the code 10GRATIS. Both of these no deposit bonuses carried a 45x wagering requirement on the bonus amount, and eligible play was limited to slots only.

There was also a no deposit free spins offer tied to the slot game Thunder Zeus, which similarly required a code to be entered manually at the cashier and came with the same 45x wagering requirement.

All of these offers have long since expired. Since the casino is now closed, there is no way to claim them or any future promotions.

The Welcome Bonus Package: Big Numbers, Tough Terms

Before its closure, Osiris Casino marketed a multi-step welcome package that looked impressive at first glance. The first deposit earned players a 300% match bonus up to €900 plus 20 free spins. The second deposit bumped that up to a 350% match plus 30 free spins, and the third deposit offered a 400% match plus 40 free spins. A minimum deposit of €20 was required at each step, and all bonuses were credited automatically - no code needed.

There was also a payment method bonus of up to $1,000, triggered by depositing with a qualifying payment method.

Here's where things got complicated: every one of these bonuses came with a 45x wagering requirement on the combined bonus and deposit amount. That means if you deposited €20 and received a €60 bonus, you'd need to wager (€20 + €60) x 45 = €3,600 before you could withdraw any winnings. That's far above the industry standard, which typically sits between 20x and 35x.

Free spins winnings were only valid on selected games, and if you requested a withdrawal before completing your wagering requirements, your bonus balance and any pending free spins were automatically cancelled. These terms were the primary reason the casino ended up on blacklists across multiple review platforms.

Games You Could Play With Bonus Funds

While active, Osiris Casino's bonus terms allowed slots to contribute fully toward wagering requirements. Live dealer games - including roulette, blackjack, and baccarat - counted for only 10% of each wager toward clearing a bonus. Some games were excluded entirely.

The Betsoft library was a highlight of the casino's slot offering. Titles like Caishen: God of Fortune brought a 243-ways structure, a Hold & Win feature, and a Buy Feature to the table - a strong pick for players who enjoy Asia-themed slots with layered bonus mechanics. The Slotfather: Book of Wins leaned into a crime and mafia theme with up to 20 free spins and a Hold & Win feature across 10 paylines.

For players who preferred something lighter, Kawaii Kitty offered a colorful 5-reel experience with a Wild Yarn feature and up to 10 coins per line. Charms and Clovers went bigger with a 6-reel layout, 40 paylines, and a Money Wheel feature packed into an Irish mythology theme. House of Fun delivered a Halloween-inspired 3D experience with multiple bonus rounds, while At The Movies gave players a Hollywood-themed slot with up to 20 free spins across 30 paylines.

These are all solid Betsoft titles that remain available at other licensed casinos.

Withdrawal Rules and Cashout Limits

Osiris Casino set its minimum withdrawal at $100 per request. Monthly cashouts were capped at $5,000, which could be a significant limitation for players who managed to build up a larger balance through bonus play. There was no VIP or loyalty program in place that could raise these limits for regular players.

Why Osiris Casino Was Blacklisted

The blacklisting of Osiris Casino by multiple independent review platforms came down primarily to its bonus terms. The 45x wagering requirement on combined bonus and deposit amounts was considered unfair by industry standards. Player complaints also centered on game contribution restrictions and time limits for using bonus funds - conditions that made it genuinely difficult to convert bonus money into real cashable winnings.

These are exactly the kinds of red flags players should look for when evaluating any online casino, regardless of how appealing the headline bonus numbers appear.

Looking for a Legitimate Alternative

Since Osiris Casino is permanently closed and was operating under terms that many considered unfair even while active, players should look toward fully licensed and regulated alternatives. If you're based in a state with legal online gambling - such as New Jersey, Michigan, Pennsylvania, or West Virginia - there are regulated platforms offering competitive welcome bonuses with far more reasonable wagering requirements, transparent terms, and proper consumer protections.

When comparing casinos, always check the wagering requirements, read the full bonus terms, and look for platforms with a clean track record. A 300% bonus headline means very little if the fine print makes it nearly impossible to cash out.
