Osiris Casino No Deposit Bonus Codes

Osiris Casino stopped taking new players and shut down on March 31, 2025. Before closure, the site ran occasional no-deposit free chip and free-spin promotions that required cashier codes, but those offers are long expired and should not be relied on. Multiple independent review platforms blacklisted Osiris Casino for unusually strict bonus conditions, so anyone researching historical codes needs to treat that history as a cautionary example.

Historical no-deposit codes and the fine print

Historically, Osiris issued short-term, code-based no-deposit offers such as GRATIS50 for a $50 free chip, 10GRATIS for a $10 free chip, and a free-spins code for the Thunder Zeus title. All of these came with a 45-times wagering requirement on the bonus, and they were restricted to certain slots. Those codes were time-limited and had to be redeemed manually at the cashier. If you find references to these codes online, remember they are archived offers from a closed operator and will not work today.

Why players flagged Osiris’ bonus terms

The main problems reported by players and watchdogs were the unusually high 45x wagering on bonus plus deposit, strict game contribution rules, and hard cashout caps. Slots counted toward wagering, but live dealer games like roulette and blackjack often counted as only 10% of the requirement, and some games were excluded entirely. Withdrawals were limited to a minimum of $100 per request and a maximum of $5,000 per month, and submitting a withdrawal before clearing wagering often cancelled bonuses and free spins. Those layers of restriction are what pushed several reviewers to blacklist the site.

What the bonus rules looked like in practice

Osiris’ welcome package was advertised as a large multi-deposit match structure — historically listed as a 300% match up to $900 on the first deposit, followed by higher-percentage matches on subsequent deposits — but those offers were tied to steep wagering and tight eligibility rules. The casino also ran a payment-method bonus up to $1,000 for qualifying deposit options. Game libraries included well-known studios such as Betsoft, which powered many of Osiris’ video slots, and titles from NetEnt like Mythic Maiden Slots. For a look at one of the studio pages that supplied games to Osiris, see the Betsoft profile, and for an example slot review, see Mythic Maiden Slots.

Rules to check before you consider any no-deposit code

When a legitimate site offers a no-deposit code, check these items up front: exact wagering requirement and whether it applies to bonus only or bonus plus deposit, game contribution percentages, maximum cashout from bonus funds, minimum withdrawal rules, and any time limits on using bonus funds or free spins. Also confirm the operator’s current licensing and reputation with independent review sites. If any term looks unusually restrictive — double-digit multipliers of the bonus plus deposit, low game contribution, or low cashout caps — treat the offer with skepticism.

Final note and safety reminder

Osiris Casino is closed and no longer accepts players; historical no-deposit codes tied to the site are expired. The casino’s support contact listed in the archive was support@osiriscasino.com and a historical phone number of +357-25-281876, but those details reflect the operator prior to closure and are unlikely to be active. Always read the full terms and conditions for any bonus, and rely on licensed, well-reviewed operators if you plan to claim no-deposit offers or welcome packages.
