There are only two promo codes worth typing at Memo Casino right now: 50HIGH for the 50%-up-to-€500 highroller top-up and RELDAY for the Sunday reload. The 255% welcome package worth up to €1,500 needs no code at all. It applies automatically. Everything else you'll see advertised, especially the "€1,500 / 40x / €20 min" headline on UK mirror pages, is either a repackaged version of an on-site offer or an outright fabrication.
I went looking for a secret code the way most players do: I typed "memo casino promo code" into Google and clicked the first five results. Four of them handed me a different string, and none of those strings did anything when I pasted them into the cashier. That tells you most of what you need to know about this brand's promo-code scene before we even get into the terms.
So let me save you the trial and error.
The codes that actually exist
Memo Casino runs a small, promotion-driven bonus system rather than a big menu of stackable codes. Here's what I could confirm directly against the operator's own /promotions/casino page, rendered on 28 July 2026. Anything not in this table, I could not verify, and I'd treat unverified codes as noise.
| Code | Offer | Who it's for | Key terms |
|---|---|---|---|
| (none) | Welcome: 255% up to €1,500 + 250 free spins, across 3 deposits | New players | Auto-applied on deposit; each step capped at €500 |
| 50HIGH | Highroller: 50% up to €500 | New & existing depositors | Bigger minimum deposit; 35x wagering (one source says 40x); 72h to use |
| RELDAY | Sunday Reload: 25% up to €100 | Existing players | Sundays only; reload on your weekend top-up |
Notice what's missing: there is no confirmed standalone no-deposit code on the official site. A single affiliate (WagerPals) reports a 20-free-spin Big Bass Bonanza no-deposit offer, but it comes with 50x wagering and a £100 withdrawal cap, and I couldn't reproduce it on the live client. Until it shows up in the operator's own promotions list, I'd file it under "maybe".
What the welcome package really looks like
Because so many pages get this wrong, it's worth spelling out. The welcome offer breaks down like this, per the operator's promotions page:
- 1st deposit: 100% up to €500 + 150 free spins
- 2nd deposit: 55% up to €500 + 100 free spins
- 3rd deposit: 100% up to €500, no spins
Add the match ceilings and you get €1,500 in bonus money plus 250 spins. No code. You just deposit and it lands. If a "welcome code" is being dangled at you, someone is either padding an affiliate page or running a mirror.
How to redeem a code
Redeeming is the easy part, and it's the same three-step routine you've seen at any Curaçao-licensed site:
- Log in and open the cashier / deposit screen.
- Choose your amount and payment method (minimum deposit varies by country: €2, €5, €10 or €15).
- Paste the code (50HIGH or RELDAY) into the promo-code field before you confirm the deposit, not after.
That last point trips people up. Codes at Memo attach to a deposit, so if you fund the account first and paste the code afterwards, you're usually out of luck, because the offer has to be selected in the same transaction. When I set up test deposits elsewhere in this network, a code entered late simply didn't register, and support couldn't retro-apply it. As far as I can tell, Memo works the same way, so type it before you hit deposit.
One more thing. Bonus funds only unlock after you've spent your real money first, and pulling your main deposit out before wagering forfeits the bonus and any winnings from it (clause 6.3). So the code is the beginning of the commitment, not a free lunch.
What existing players actually get
This is where the "bonus codes for existing players" search intent runs into an uncomfortable truth: most of the ongoing value at Memo isn't a code at all. It's loyalty-gated.
The two things existing players chase, cashback and rakeback, arrive automatically based on your play, not on a string you type:
- Weekly cashback up to 25%. Scales with your loyalty rank; lower tiers get a much smaller slice.
- Rakeback up to 17%. Again, the headline figure is the top-tier number, not what a casual player sees.
- Sunday Reload. The one existing-player perk that does use a code, RELDAY, for 25% up to €100.
So the honest answer to "is there a promo code for existing players?" is: one, RELDAY, plus a highroller top-up with 50HIGH if you deposit big. The cashback and rakeback that people assume need a code are earned, not entered. That's better than fake codes in one sense (you don't have to hunt for them) but worse in another: the juicy 25% and 17% ceilings belong to whales, and there's no code that shortcuts you up the VIP ladder.
Tournaments sit in the same bucket. The Rookie Rumble (€2,500 daily), Daily Bronze (€2,500) and the €10,000 Live Tournament are opt-in ladders, not code redemptions. Network drops like Drops & Wins run on top. None of them need a promo string.
The terms behind each code
A code is only as good as the wagering behind it, and here Memo is middle-of-the-road at best.
50HIGH. Fifty percent up to €500 sounds generous until you read the fine print. It carries a higher minimum deposit than the standard welcome, the wagering sits at 35x (one affiliate source claims 40x, and I'd assume the worse number until the operator's bonus-terms page says otherwise), and you get roughly 72 hours to use it before it lapses. For a highroller offer, that clock is tight.
RELDAY. The Sunday reload is a smaller, friendlier offer at 25% up to €100, but it's a once-a-week window and the reload cap is low enough that it's a top-up, not a bankroll. Fine as a habit, not a game-changer.
Welcome (no code). The general bonus rule (clause 6.3) is the one to internalise: bonus funds are usable only after real funds are spent, and cashing out your deposit early kills the bonus. That's standard for the sector, but it means the €1,500 headline is a wagering commitment dressed as a gift.
Across every code here, the same site-wide rules bite: withdrawals demand a 3x playthrough of your active deposits before you can cash out (clause 7.6), and any win over €10,000 is paid in monthly €10,000 installments (clause 7.13). A big win off a bonus code doesn't arrive as one lump sum.
Fake codes and mirror-site traps
Now the warning, because this is the part that costs people money.
Memo Casino sits behind a sprawl of look-alike domains: memo-uk.com, memocasino-uk.app, memocasino.co.uk, thememocasino.com and more. Many of these are affiliate or mirror pages, not the operator, and their bonus figures don't match the real site.
The clearest tell is that "€1,500 + 250 FS, 40x wagering, €20 minimum" headline you'll see splashed across UK mirror pages. It's a fabrication, or at best a mangled remix. The operator's own promotions page states €500 per step and €1,500 total across three deposits, and the offer wording differs by domain. Whenever a code or a headline bonus doesn't line up with what's on the account you're actually logged into, trust the cashier in front of you, not the affiliate banner that sent you there.
Three habits that have saved me grief:
- Only enter a code that appears inside your logged-in Memo cashier or on the operator's own promotions page. If it lives only on a review site, it's unverified.
- Ignore codes that promise "no wagering" or a suspiciously round headline. Memo's real offers all carry wagering.
- Check the domain in your address bar before depositing. A code that "works" on a mirror can attach to different, worse terms than the same string on the official client.
Where the promo-code angle falls short
Let me be blunt about the downsides, because a codes page that only sells you codes isn't much use.
First, there just aren't many real codes. Two of them, 50HIGH and RELDAY, plus an auto-applied welcome. Compared to bonus-heavy rivals that publish a fresh weekly code, Memo's cupboard is bare, and the recycled affiliate codes floating around simply don't work.
Second, existing-player value is loyalty-gated, not code-gated. The 25% cashback and 17% rakeback that get quoted are top-tier ceilings. A normal player sees a fraction of that, and no code moves you up.
Third, and this is the one UK readers must not skip, the codes are academic if you're in Britain. The UK is a Restricted Country under Memo's own Terms (clause 4.5), the operator holds a Curaçao licence and no UKGC licence, and it is not connected to GAMSTOP. UK players have reported deposits accepted and then accounts disabled with withdrawals withheld (documented on casino.guru). A working promo code is no protection if you can't lawfully withdraw. This is a review, not an endorsement, and 18+ applies throughout.
How I checked this
I read the operator's live promotions and terms pages directly (rendered 28 July 2026), cross-checked every code against those pages rather than against affiliate write-ups, and treated any code I couldn't find on the official client as unverified. Where sources disagreed, the 35x versus 40x wagering on 50HIGH being one instance, I've flagged both and told you which I'd assume. Bonus terms change, so confirm the current wagering and caps on the operator's bonus-terms page before you deposit.

Promo code FAQ
What is the Memo Casino promo code?
The two active codes are 50HIGH (highroller, 50% up to €500) and RELDAY (Sunday reload, 25% up to €100). The 255% welcome package worth up to €1,500 plus 250 free spins needs no code - it applies automatically on your first three deposits.
Is there a code for existing players?
Yes, but only one: RELDAY for the weekly Sunday reload. Beyond that, existing-player value comes as loyalty-based weekly cashback (up to 25%) and rakeback (up to 17%), which are credited automatically by VIP rank, no code required. The highroller code 50HIGH is also open to existing depositors.
How do I enter a bonus code?
Log in, open the cashier, choose your deposit amount and method, then paste the code into the promo-code field before you confirm the deposit. Codes attach to the deposit, so entering one afterwards usually won't work and support generally can't apply it retroactively.
Do the codes work for UK players?
Practically, no. The UK is a Restricted Country in Memo Casino's own Terms (clause 4.5), the site holds no UKGC licence and isn't on GAMSTOP. UK players have reported accounts being disabled and withdrawals withheld after depositing, so a valid code offers no real protection. Beware, too, of UK mirror sites advertising a fake "€1,500 / 40x / €20 min" headline that doesn't match the official offer.
