Diomedes Limited is a Malta-licensed operator that runs a single online casino, ComeOn!, built specifically for the Norwegian market. The brand first launched in 2010 and forms part of the wider ComeOn Group, one of the more established names in European iGaming.

MrWager rates Diomedes Limited among the more reliable Malta-licensed operators serving Norway, thanks to a strong regulatory backing and a clean record. The licence comes from the Malta Gaming Authority, the gold standard for player protection, and the operator carries a high-trust reputation. The one thing to keep an eye on is strict KYC verification. It’s standard at MGA casinos, but it can slow down your first withdrawal.

Shared Features & Network DNA

Welcome Offers & Loyalty

The welcome offer comes in two versions. Casino players can claim a 500% match up to €50, while live players can take a 100% match up to €10 on Evolution Gaming tables instead. The match percentage looks generous, but the caps keep the value modest.

Regular promotions are thin. The bigger draw is the rewards setup. You earn points just by playing and completing tasks, then spend them in a bonus shop on free spins, bonus cash, and other items. There’s also a weekly featured game with point multipliers to chase.

The standout is the group’s exclusive Power Up Jackpots system. Activate an extra bet on selected slots or live games and you unlock four progressive tiers — Mini, Minor, Major, and Mega — with a top prize of up to €100,000. A premium tier piles on over €5,000 in extra prizes. On top of that, the operator runs the odd no-deposit free spins or bonus money offer. There’s no public VIP program, though high rollers and very active players may pick up exclusive perks at the casino’s discretion.

Common Terms & Conditions

Minimum deposit to trigger a bonus is €10. The casino welcome bonus carries a 35x wagering requirement on deposit plus bonus. The live casino version is lighter at 30x deposit plus bonus. Either way, you get a generous 30 days to clear it — far more breathing room than most online casinos offer.

Game Selection

Game choice is a real strong point. You’ll find over 9,000 titles from roughly 100 studios, headlined by Pragmatic Play, Play’n GO, NetEnt, Hacksaw Gaming, Nolimit City, and Relax Gaming. BGaming is the one notable absentee.

The live casino leans on the best in the business. Evolution runs the bulk of the tables, backed by Pragmatic Play Live, Playtech, and On Air. Jackpot hunters are well covered too. The lineup spans Mega Moolah, LotsaLoot, Dream Drop, Wowpot, and Age of Gods, plus NetEnt classics like Mega Fortune, Divine Fortune, and Arabian Nights.

There’s also a deep bench of instant-win and crash games — Aviator, Spaceman, High Flyer, Big Bass Crash, Mines, Limbo, and more. A few group exclusives round things out, including Book of Evil, Major Miners, Ramses Retro, and Hoggin’ Gold.

Payment Ecosystem

Deposits start at €10 and withdrawals at €20, with no withdrawal limits to worry about. Supported methods include Visa, Mastercard, cryptocurrencies, LuxonPay, and MiFinity — so the cards and e-wallets most Norwegian players rely on are all covered. One thing to flag: a €5 fee kicks in from your third withdrawal within any 30-day cycle.

Licensing and Safety Analysis

The operator holds a Malta Gaming Authority licence, the strongest ticket an offshore casino can carry for Norwegian players. That brings real obligations: certified RNGs, independent game testing, segregated player funds, and full GDPR compliance. Responsible gambling tools are in place too, including deposit limits, reality checks, and self-exclusion. Disputes go through eCOGRA, an approved alternative resolution body. In short, the safety framework here is about as solid as it gets.

  • Network Reputation: High-trust, backed by the established ComeOn Group.
  • Warning/Trust Signals: Strict KYC. Expect thorough verification before your first payout clears. 
  • Rebranding History: ComeOn! was previously operated by Co-Gaming Limited, now known as the ComeOn Group.

Verdict

On trust, there’s very little to pick at. The MGA licence is the strongest available at offshore casinos for Norwegians, the operator carries a high-trust reputation, and there’s no messy rebranding history in the rear-view mirror. Payouts back that up. Most withdrawals clear within 24 hours once your documents are verified, and there are no monthly limits to cap a big win. Just be ready for thorough KYC checks, since that’s where most of the friction lies.

The welcome offer is where expectations need tempering. A 500% match sounds huge, but it’s capped at €50, so the cashable upside is small. Where this operator really earns its keep is the long game — a points-and-rewards shop, weekly multipliers, and the Power Up Jackpots.

For Norwegian players who want a trustworthy MGA casino with fast cashouts and a deep game library, and who care more about ongoing rewards than a flashy sign-up bonus, ComeOn! under Diomedes Limited is an easy pick.
