OlympusBet Casino review

OlympusBet is an Anjouan-licensed online casino and sportsbook that launched in 2024 under the operator Admiral Entertainment Limited. New players can begin with a four-part welcome bonus offering 100% up to €500 + 100 free spins, and the site backs this up with regular reload deals for casino and sports, plus there are slot tournaments with wager-free prize payouts.
The real draw, though, is a sprawling game library built around high-volatility slots, a busy jackpot lobby and live tables from eight studios.

Licence and Regulation

WinMega operates under a licence issued in the State of Anjouan under the Computer Gaming Licensing Act 007 of 2005, holding license number ALSI-202505009-FI1. The operator, Admiral Entertainment Limited, holds the licence and governs the site's gaming operations. It’s not the most transparent licence compared to alternatives such as Curaçao's CGA, which specialises in crypto and fiat currency regulations, or the Malta Gaming Authority, under which most online casinos accept Euro deposits and no crypto.

Security and Player Protection

The casino operates under several player-protection measures, including encrypted data transmission to safeguard personal and payment details, secure payment processing through its supported providers, and a documented KYC process that verifies player identity as both a security and compliance step. Also, the main URL uses HTTPS, and therefore connections use SSL/TLS encryption.

The site also publishes a Self-Exclusion Policy, an Underage Gaming Policy, and Responsible Gaming resources, providing players with advice on responsible gambling and an option to self-exclude by requesting support. However, there are no responsible gambling tools, such as deposit, loss, or wager limits.

What we like

• You’ll have access to casino games and sports betting in one place with the choice of a first deposit welcome bonus for each gambling vertical
• Weekly casino and sports betting reload bonuses, regular leaderboard promotions, and monthly free bets
• High €12 maximum bets for bonuses compared to most competing online casinos

What we don't like

• Curaçao licence offers lighter player protection than an MGA-licensed casino that accepts euros
• No responsible gambling options to set deposit, loss, session or wager limits
• Welcome bonus’s 40x (d+b) wagering requirements are above the industry average, plus there is a 5x deposit turnover for free withdrawals

OlympusBet Casino Overview

Overview of Available Bonuses at OlympusBet Casino

OlympusBet leans heavily on bonuses, from its headline welcome package to weekly reloads and long-running tournaments that include casino and sports deals; plus, roulette players can also take advantage of some of these offers. Claiming an offer is straightforward: register an account, verify your email through the activation link, make a qualifying deposit, and opt in to the relevant promotion before you play.

• 💡Expert Tip: When you receive a bonus balance, it becomes active only after your real money balance has been used. Also, while any bonus is active, real money bets do not count towards the bonus rollover.

Step-by-step Registration and Bonus Activation Guide

• Choose the ‘Register’ option to sign up; at the same time, select the ‘Casino’ or ‘Sports’ welcome bonus, or you can opt out
• Enter your email address and password, then accept the T&Cs, and choose whether you want to receive promotional emails
• Enter your personal information (first and last names, telephone number, country, currency, date of birth and address) and select ‘Create Account’
• At the cashier, choose a payment method and deposit at least €20. Oddly enough, we didn’t need to enter a bonus code, despite the promo page providing us with one. Under our account ‘Messages’ section, we had a message stating ‘Bonus code successfully activated’.

Casino Welcome Bonus - 100% up to €500 + 100 Free Spins

You’ll be greeted with a four-part welcome bonus that predominantly suits online slot players, especially as the second, third and fourth deposits offer free spins and no deposit match. For the first deposit bonus, virtual roulette players may find this offer useful. The main difference between both game types is that most slot games contribute 100% towards wagering, while roulette, excluding live dealer variants, counts only 10% of your bets towards any bonus wagering.

• First Deposit: 100% deposit match up to €500 + 25 Free Spins on Rags to Witches, Book of Darkness, or Gears of Time (Bonus Code: OBWEL100)
• Second Deposit: 25 Free Spins on Trinity Reels or Primal Wilderness (Bonus Code: OBWELFS2)
• Third Deposit: 25 Free Spins on Gemini Joker or The Hive (Bonus Code: OBWELFS3)
• Fourth Deposit: 25 Free Spins on 7 Fortune Frenzy or Stampede (Bonus Code: OBWELFS4)

Main Bonus Rules

• 🤔 Quick Summary: You’ll need to claim your free spins over four separate deposits. First, you’ll need to use your free spins before you make any other bets, and winnings will credit your bonus money balance. The 21-day validity on your bonus balance is more than fair in case you do play through your real money balance; however, converting your bonus balance into real money is not going to be easy, as the 40x (deposit + bonus) rollover is higher than average.

Sports Welcome Bonus - 100% up to €200

When registering for a new account, you will have the option to opt in to the OlympusBet sports betting bonus for your first deposit to replace the casino deposit match + free spins, then claim the second, third, and fourth deposit free spins after.

• First Deposit: 100% deposit match up to €200 (Bonus Code: OLYMPUS200)

We didn’t claim the sportsbook welcome bonus, but if you select it when you deposit, we are confident the OlympusBet bonus code will automatically be applied in the same way as the casino bonus.

Main Bonus Rules- Sports Welcome Bonus

• 🤔 Quick Summary: The sports betting first deposit bonus comes with lower wagering requirements than the casino offer, which is a plus. Just make sure that if you do get to use your sportsbook bonus balance, you do not place bets below 1.80, and you should also read the rules regarding restricted gameplay.

Reload Bonus Offers, Cashback Bonus and Other Promotions

OlympusBet keeps a rotating set of promotions running for casino and sports betting players. Casino players can claim a weekly reload, while time-limited online slot software promotions with dedicated prize pools that pay out 0x wagering prizes run through the promo section weekly and monthly. Plus, if you are a sports betting fan, you can kickstart your month with free bet tokens, and each time you deposit, you can top up with a reload, giving you a bonus balance to place bets.

• Reload Bonus: Once per week, you can claim a 50% deposit match up to €200. Deposit at least €20 with the bonus code RELOAD50OB. The bonus rollover is the same as the welcome bonus at 40x (bonus + deposit), and also slots count 100% and virtual roulette 10%.

• Time-limited bonuses (leaderboards & prize drops): OlympusBet regularly runs seasonal, rotating promotions with prize pools. Play qualifying games to earn points that contribute to tournament leaderboards or for the chance to land random prize drops. Regardless of the promotion, all prizes are awarded with no wagering requirements. Since these events refresh frequently, keep an eye on the promotions for the latest tournaments and prize drops.

• Sports Reload Bonus: Claim a 50% deposit match up to €50 for deposits of €20 or more along with the bonus code OLYLOAD50. There’s a 5x deposit rollover, and all bets must be 1.80+.

• Free Bet Tokens: On your first (up to €10), second (up to €15), and third (up to €25) deposits of the month, you can claim €50 in free bets. There is 0x wagering as long as you bet on single pre-match bets only with odds of between 1.80 and 3.00. There’s no promo code, so you’ll need to visit the promotions page, select ‘Spots’, ‘€50 FREE BET TOKENS’ and choose ‘Claim Now’.

VIP and Loyalty Program

OlympusBet runs an invite-only VIP Club, so getting there isn’t based on earning points. Therefore, there’s no VIP ladder to climb, which is a system commonly used by most rival casinos and sportsbooks.

As a member of the VIP program, you’ll receive the following benefits:

• Dedicated account manager
• Priority assistance
• Custom promotional offers
• Exclusive prizes and rewards
• Faster withdrawals
• Tickets to events
• Gifts and special birthday and loyalty treats

The main downside to this setup is that there is no chance to earn coins to spend in a bonus shop, and even if you are a regular player playing on a budget, unlike many other casinos, there’s no reward for your regular play.

The Game Providers and iGaming Lobbies at OlympusBet Casino

OlympusBet spreads its content across casino slots, a live casino, virtual sports, and a full sportsbook with esports. The casino lobby hosts more than 8,000 games, which you’ll find under categories like Slots, Top, New, Provider Spotlight, Book of Slots, Bonus Buy, Jackpots, Table Games, Megaways and Casual.

The one area we’d like OlympusBet to improve is the filtering system, which we’d like to see more like an e-commerce website or, at the very least, an option to sort slots by low, medium and high variance.

Slot Machines, Jackpot Slots and Instant Games

Slots are the heart of the site, with 67 slot studios feeding the lobby. The selection is tilted firmly towards high-volatility play, with dedicated Book of Slots, Bonus Buy and Megaways sections front and centre for players chasing bigger swings.

There is also a jackpot lobby, which is mostly made up of fixed jackpots, but it mixes in progressive titles from Betsoft, Yggdrasil and Play’n GO such as Greedy Goblins, Dr Fortuno and Leprechaun Goes to Hell, and the site advertises a combined jackpot pool in the region of €2.6 million.

• 🤓 We particularly liked this slot game: Money Train by Relax Gaming, because OlympusBet hosts all four versions of the game, three with 40 paylines and one with pay anywhere. They also all cater to bonus buy players looking for high-volatility gameplay. Plus, the pay anywhere variant Money Train 4 is an award winner, taking down the Online Slot of the Year at the Global Gaming Awards EMEA 2024.

Live Casino as well as Table and Card Games

The live casino is powered by eight studios: Pragmatic Play, Evolution, Skywind Group, Vivo Gaming, Lucky Streak, AG (Asia Gaming), BetGames and Ezugi.

That line-up covers all the classics, such as live roulette, blackjack, baccarat and game shows, with Evolution and Pragmatic Play in particular bringing a deep bench of high-quality tables and live casino game shows.

• 🤓 Top live casino games for high rollers: Evolution’s VIP and Salon Privé roulette and blackjack rooms where tables come with minimum bets of €500 to €1,000 and maximum bets of up to €10,000.

SportsBook

Alongside the casino, OlympusBet is a full sportsbook. It covers major sports including football, basketball, tennis and volleyball, with live/in-play betting, virtual sports and esports markets, and it advertises regularly updated odds across international leagues. You also have the option to use an ‘Event Builder’ by combining two teams from separate events into a single pre-match bet from football and basketball betting markets.

OlympusBet Casino Deposits and Withdrawals

The cashier is as clearly laid out as they come, leaving no room for confusion. The min/max deposit amounts are featured for each payment option, including bank cards, an e-wallet, crypto, a popular banking option and a digital payment voucher. It’s not the largest selection of deposit methods available, but they are some of the most common.

Deposits

• Bank Cards (Visa, Mastercard)
• E-wallets (Skrill)
• Banking (Revolut)
• Vouchers (Paysafecard)
• Crypto (USDT, BCH, BTC, ETH, LINK, LTC, SOL, USDC, XLM, XRP)

The minimum deposit for bank cards, Paysafecard, and Revolut is €10, then €15 for Skrill and €20 for crypto. High rollers depositing in euros will likely prefer Revolut as the max deposit is €5,000, while all other options are limited to €1,000, unless you’d prefer to deposit using crypto, which, like Revolut, has a maximum deposit of €5,000.

Withdrawal Duration, Limits, Verification and KYC

• Bank Cards (Visa, Mastercard)
• E-wallets (Skrill)
• Banking (Revolut)
• Crypto (USDT, BCH, BTC, ETH, LINK, LTC, SOL, USDC, XLM, XRP)

When cashing out, all available withdrawal options require a minimum of €20. The maximum limit is stated in the T&Cs as €5,000 per rolling 7-day period, but VIP players may be provided with higher withdrawal limits. Before withdrawing, you must complete a 5x rollover of your deposits to avoid an 8% admin fee.

If you make multiple withdrawal requests in a short space of time, the casino may reject them or charge an 8% admin fee. Also, if you have not verified your account via a KYC check, you will not be able to withdraw.

• 💡Expert Tip: Verify your account as soon as possible to avoid delays when cashing out. You can complete the verification through a document-upload form accessible via the settings page of the website, and ask live chat for assistance with this.

Website Design, Usability and Mobile Use

The OlympusBet site has a dark, gold-accented theme with a clear top menu splitting Home, Casino, Live Casino, Virtual Sports, Sports, Live Betting, Esports and Promotions. Navigation inside the casino is handled by a secondary category bar to access Slots, Top, New, Bonus Buy, Jackpots, Megaways and more, plus a provider filter, so finding a game or studio is quick. Pages load smoothly, the account and cashier areas are easy to reach, and the bonus section is grouped under a single Promotions tab with ‘All’, ‘Sport’, and ‘Casino’ filters.

Casino App

There is no dedicated downloadable app; OlympusBet is browser-only and advertises play across PC, Mac and mobile, so you simply load the responsive site in your mobile browser to play on the go. On mobile, we tested navigation on different screen sizes and the layout scales responsively on smartphones and tablets.

Experience with Customer Support at OlympusBet Online Casino

OlympusBet promotes round-the-clock help through two channels, backed by a reasonably detailed FAQ and a clear complaints/ADR path for anything that cannot be resolved directly. There are also footer links with a wealth of self-help info, and you can email the support team if you’re not looking for an urgent response.

How to Contact OlympusBet Customer Support

• (Live Chat): Open 24/7 for real-time support
• (Email): Send emails to [email protected]
• (Complaints): There is a ‘Dispute Resolution’ section in the footer explaining the process of logging and how the site deals with complaints
• (ADR): If a complaint is unresolved, you can escalate to the Curaçao-authorised ADR by emailing [email protected].
• ❓Contact with live chat: Does OlympusBet offer loyalty rewards for regular budget players who wager between €500 and €1,000 per month?

The live chat support agent, Miles Q, was online instantly and was completely honest, saying that the VIP program is reserved for high-value customers, but that doesn’t mean the VIP program is closed to players who play through the amounts mentioned. It’s at the discretion of the VIP team.

Comparing OlympusBet Casino with iGaming Competitors

There’s always competition on the iGaming and sports betting market, and so we’ve chosen two alternative online casinos to give you a head-to-head matchup covering some of the key decision-making factors many players consider when choosing a website to gamble on.

Instasino Casino

120% up to €750 + 125 Free Spins

Play

4.1 / 5.0

Wintari Casino

200% up to €1,000

Play

3.9 / 5.0

OlympusBet has the strongest licensing framework of the three casinos compared. It also beats its two competitors when it comes to game variety thanks to the higher number of software providers. Where it does lose to Instasino and Wintari is its high 40x deposit + bonus rollover. Wintari offers a lower bonus amount and no free spins, but its 30x wagering requirement gives players a more realistic chance of converting the bonus into real money.

Rounding Up Our OlympusBet Casino Experience

Our first impressions of OlympusBet were that it is a modern, Euro- and crypto-friendly casino and sportsbook with depth in games and sports betting markets. There are 67 online slot studios and 8 live dealer studios, making it 75 software providers, which isn’t the highest number we’ve seen, but it’s plenty to keep any slot machine or live dealer player fully entertained. As a member, you also have access to a responsive support team ready and waiting to help 24/7.

If you are a high roller, you’ll likely be invited to the VIP club where the casino lays out the red carpet as a token of appreciation for playing on OlympusBet. Conversely, the VIP system is a bit of a letdown for budget players, as there’s no reward for regular play. Another disadvantage worth pointing out is the high bonus wagering requirement on the welcome bonus, and for free withdrawals, there’s a high 5x deposit turnover. The casino also lacks standard responsible gambling tools.

For players who value game variety, OlympusBet is well worth a look; head to the site to check the current welcome package and promotions before you sign up.
