Mail-in sweepstakes casinos let you request free Sweeps Coins via post (AMOE), so you can enjoy casino-style games without purchase. If you’ve wondered how sweepstakes mail-in entries work – or which sweepstakes casino by mail is worth your time – this guide has you covered.
Below you’ll find the best free casino mail-in sweepstakes, exactly how to enter sweepstakes by mail (with a template and envelope format), real mailing addresses, processing timelines, and compliance tips. We’ll also compare mail-in vs online entry, link to official rules/terms, and share quick troubleshooting so your postcard isn’t disqualified.
I found quite a few mail-in sweepstakes casinos that are offering you a chance to claim some free Sweeps Coins. After reviewing them, I narrowed the list down to the sites that stood out the most – Stake.us, McLuck, and WOW Vegas.
All three of these sweepstakes casinos offer a mail-in bonus, but they each have specific conditions. For example, all three sites require you to handwrite your request on a standard-sized postcard. You also need to generate a unique mail-in code, which is associated with your account only.
Check out the full requirements and details below:
| Sweepstakes casinos | Mail-in bonus | Requirements | What to include | Postal address |
|---|---|---|---|---|
| Stake.us | 5 Stake Cash | Handwrite the info on a postcard in black ink |
| Sweepsteaks Limited, 13101 Preston RD STE, 110-5027, Dallas, TX, 75240 |
| McLuck | 4 Sweeps Coins | Handwrite the request on a postcard in black ink |
| Sweepstakes, B-Two Operations Limited, PO BOX #9550, Manchester, NH, 03108 |
| WOW Vegas | 3 Sweeps Coins | A handwritten request on a postcard in black ink |
| MW Services Limited, 1445 Woodmont, LN MW #720, Atlanta, GA, 30318 |
I want to look closer at my top three mail-in online sweepstakes and uncover what they offer. I’ll unpack the number of free Sweeps Coins you get and give you a rough overview of the mail-in process. I also touch on other interesting aspects like the number of free sweepstakes games on display and welcome deals.
Firstly, I must commend Stake.us for the generous welcome bonus of 55 Stake Cash + 260K Gold Coins + 5% Rakeback, which extends to new players. You must enter the promo code SPORTSGRID to unlock it. As for free Sweeps Coins, you get 5 Stake Cash with each mail-in request.
Your request must be written on white, unfolded paper that’s at least 4×6 inches. Next, you place the paper inside an envelope hand printed “Stake Cash Credits”. Make sure you include a return postage. I like how you can send multiple requests, provided you include one request with each envelope.
Armed with your free credits, you have a stunning games library bursting with over 1,000 games from top studios to explore. You can redeem Sweeps Coins when you accumulate a minimum of 30 SC and play them through 3x. I like the low minimum SC threshold but found the playthroughs steep.
McLuck’s welcome bonus of 7,500 GC and 2.5 SC may not be as glamorous as Stake.us, but you still get 4 free Sweeps Coins via mail. It’s one of the few mail-in sweepstakes that need you to include a 13-digit code with your request. You can request this one-time code on the platform. A word of advice? Make sure you include the code to avoid any unnecessary delays.
I found McLuck’s mail-in request process to be quite reasonable. You’ll need a standard #10 business envelope and a blank card—like an index card. It’s on this card that you pen your request legibly in any ink color other than black. Include basic information like your full name, return address, and email address. Don’t forget the request code.
McLuck does pretty well with its gaming library, which has over 700 games from top studios like NetEnt. Many of these games are slots though, including a few Slingo titles. This may be a deal breaker if you’re more into table games or video poker. You need a minimum of 75 SC to claim prizes, and I do like the low 1x wagering conditions.
WOW Vegas stuns with a massive welcome bonus comprising 250,000 WOW Coins and 5 Sweeps Coins. With this mail in sweepstakes casino, you can add 3 more free Sweeps Coins to your balance if you ask kindly. I like how you can forward your requests as many times as you like. But of course, you can only include one request per envelope.
Like with most of the free sweepstakes sites on my list, you need to use a #10 envelope to request your free Sweeps Coins. Include your return address and clearly mark the envelope with the words “REQUEST FOR SWEEPSTAKES CREDITS”. You must write your request on white paper using black ink and include your full name, email address, and mailing address. Players must also include a 16-character code generated from the platform.
Over 900 quality slots from leading studios like Betsoft are there to play. When it’s time to request winnings, you need at least 100 SC in your account, which is a much higher limit compared to its peers. WOW Vegas takes three days to process your winnings via banking methods like Skrill and Trustly.
To help you pick a site from my recommended mail-in sweepstakes list, I will include a quick comparison table below. I will compare features like bonus delivery, eligibility requirements, and so on.
| Casino | Sign-Up Bonus | Bonus Code | Mail-In Bonuses | Mail-In Bonus Speed | Cost Per Entry | Excluded States |
|---|---|---|---|---|---|---|
| Stake.us | 560,000 GC + 56 Stake Cash + 5% Rakeback | SPORTSGRID | 5 SC | 2-3 weeks | Postage | CT, DE, ID, NV, NJ, NY, KY, LA, MD, MI, MT, PA, RI, VT, WA, WV |
| McLuck | 7,500 GC + 2.5 SC | – | 4 SC | 2-3 weeks | Postage | CT, DE, ID, LA, MD, MI, MT, NV, NJ, NY, KY, WA, WV |
| WOW Vegas | 250,000 WC + 5 SC | – | 3 SC | 2-3 weeks | Postage | CT, ID, MI, MT, NV, WA |
All sweepstakes casinos are different, and the same goes for mail-in bonuses, too, which can make it difficult to choose the right site for you. Let’s take a look at some of the key areas you should focus on when handpicking the best sweepstakes casino for your needs.
You should look at the number of free Sweeps Coins you will receive. While WOW Vegas has the lowest mail-in bonus with 3 Sweeps Coins, it is still a great deal. Let’s face it, 3 Sweeps Coins are better than none.
The main pitfall of a mail-in bonus is how long you need to wait to receive your free Sweeps Coins. As you are sending your request via snail mail and it requires a team to manually go through all the postcard entries, it is far from instant. You are looking at weeks before you will receive the bonus, so make sure that you are prepared to wait.
All of the sweepstakes casinos on this page have a clear-cut claiming process with as few requirements as possible. Look out for sites that have a streamlined process, so you do not have to jump through many hoops.
Only join reputable mail-in online sweepstakes sites. Read guides on our site like this one and read real customer reviews, too. This will give you an overview of the player experience and any indication of whether they do not fulfil the mail-in bonus requests.
Here’s a list of pros and cons of playing at mail-in sweeps casinos, so you walk in knowing what you stand to get.
Use this quick side-by-side to decide when to send a postcard (AMOE) and when to stick with in-app/online freebies:
| Factor | Mail-In Sweepstakes Entry (AMOE) | Online/In-App Freebies (No Purchase) |
|---|---|---|
| Speed | Slow: typically 2-3 weeks for review/crediting | Fast: often instant to 24 hrs (daily login, codes) |
| Typical Reward | 3-5 SC per accepted entry (e.g., WOW Vegas 3 SC, McLuck 4 SC, Stake.us 5 SC) | 0.5-2 SC daily + Gold/Play coins; occasional larger drop codes |
| Cost | Postage + materials (card/envelopes); no purchase | $0 (time only); no postage |
| Effort | Higher: hand-write card, include unique code, return envelope, correct size/ink | Lower: log in, claim daily, redeem codes, join promos/referrals |
| Caps & Limits | Usually 1 entry per envelope; some brands allow multiple separate entries | Daily claim limits; drop codes often first-come, capped redemptions |
| Rejection Risk | Moderate: disqualifications for wrong ink/size/missing return address/code | Low: mistyped code or expired link is the common failure |
| Wagering | Brand-specific (e.g., Stake.us 3×, McLuck 1×, WOW Vegas 1×) | Same brand rules apply to SC earned via daily/login/codes |
| Best For | Maximising free SC value when you’re patient and detail-oriented | Building a steady baseline of SC/GC with minimal effort |
| KYC Impact | KYC still required to redeem prizes (regardless of entry method) | KYC still required to redeem prizes |
When to choose mail-in (AMOE)
When to choose online/freebies
Best strategy: do both
US sweepstakes casino laws and regulations require all sites to allow customers to play for free. As such, mail-in sweepstakes offer alternative modes of entry (AMOE), where you can get your hands on certain promotions for free with no purchase necessary. Let’s unpack more on the specific rules of mail-in bonuses:
The law states that those who enter promotions using Sweeps Coins from mail-in sweepstakes must have equal opportunities to win the same prizes as those who pay to enter. In other words, AMOE must have the same winning odds as all other forms of entries.
Mail-in bonuses are accessible to all by design, as that is the whole purpose of AMOE. All you need to do is send a handwritten postcard to the address, as outlined in the bonus terms and conditions.
Most mail-in sweepstakes casinos have a strict list of requirements, which you must follow. If you fail to fulfil one or more of the requirements, you will be at risk of disqualification. For example, Stake.us has a strict postcard size of 4×6, and generally, all sweepstakes casinos require your writing to be handwritten in black ink.
Typically speaking, you must include certain details like your full name, return address, email address that is linked to your account, and a unique code. When it comes to the code, you will usually have to request a code that will be unique to your account.
It is your responsibility to cover the cost of the return postage, so you will need to include a stamped envelope with your return address written on it. If you fail to include this, your request will be denied.
Now, let me walk you through the process of sending your mail-in request to a standard mail-in sweepstakes casino. I will also include a checklist to help ensure your mail entry is successful.
While the exact process may differ depending on the sweepstakes casino, the steps will generally look like this:
Use the following checklist to help remember what you may need:
Depending on the sweepstakes casino, you may need to include some additional bits of information. Likewise, not everything in the above checklist will necessarily be required, so use this as a guide.
Use this as your fill-in template. Always double-check each casino’s T&Cs for exact ink color, paper size, and whether a stamped return envelope (SASE) is required:
Write clearly (block capitals). Many sites require black ink; a few specify not black – verify first:
REQUEST FOR SWEEPSTAKES CREDITS (AMOE)
FULL NAME: Jane Q. Player
USERNAME: JaneQPlayer
ACCOUNT EMAIL: jane.q.player@email.com
RETURN ADDRESS: 123 Maple Ave, Austin, TX 78701
UNIQUE MAIL-IN CODE: ABCD-1234-XYZ9 (from your account)
STATEMENT: I am requesting free Sweeps Credits via AMOE. I meet the eligibility requirements and agree to the Official Rules.
SIGNATURE: ____________________DATE: 2025-08-30
Use a #10 business envelope unless the casino specifies otherwise:
Front:
[CASINO NAME / SWEEPSTAKES DEPT]
[Exact mailing address from their T&Cs]
(OPTIONAL, IF REQUIRED): “REQUEST FOR SWEEPSTAKES CREDITS”
Include inside: your handwritten postcard. If required: add a stamped, self-addressed return envelope (SASE) with your return address.
Processing is typically 2-3 weeks by mail. If nothing arrives after that window, contact the casino’s support with the date sent and the code you used.
The thing about mail-in bonuses is that after sending your request, you are not guaranteed to receive the bonus. After all, there are a few ways that can get you disqualified, such as forgetting to include a required detail. Here are a few scenarios and bumps that you might encounter along the way, and how to fix them:
The mail-in bonus conditions can be a bit lengthy, so it can be somewhat easy to miss something. Most commonly, players forget to use the correct color ink or do not write their return address on the second envelope. Double-check your checklist to make sure everything has been included, as it can be weeks before you find out you are not eligible.
If you have a query about the entry requirements or have a question post-request, then you should reach out to the customer support team at your earliest convenience. Contact the team via email or the website, and someone will be in touch to offer assistance.
If you find out that your mail-in request has been rejected, you can try to contact customer support to see if they can help give you an idea why this happened. As I said earlier, some common mistakes are easier to make than you might think. When you learn where you went wrong, you can try again.
Prizes are distributed in different ways, depending on your sweepstakes casino. For example, some sites might use random draws while others will use free instant win sweepstakes, where the winner is announced right away. Either way, this process is usually automated to eliminate bias and foul play.
Once again, how winners are notified will vary, but most commonly, you will find out via mail or email. However, you may be contacted via text message or phone call, for example. If your sweepstakes casino has a newsletter, winners might also be announced that way.
When it comes to claiming your prize, you may be asked to submit a few documents or fulfil certain requirements. For instance, most sweepstakes casinos require your account to be fully verified. In this case, you will need to submit a copy of your photo ID and proof of address.
The timeline will differ, depending on the process of your chosen sweepstakes casino. Generally speaking, you will find out as soon as the promotional period has ended, which will be detailed in the terms and conditions.
During my investigations, I found that not all mail-in sweepstakes sites run legit operations. There are real threats out there, so you need to be vigilant when it comes to identifying the bad apples who are looking to rip off unsuspecting players. To help you not fall victim to scammers, I have included a few red flags to be wary of:
While you are required to cover the postage, you should not be asked to pay any additional fees. Having said that, if you get a request to pay charges because your letter is ‘stuck at customs’, this is a red flag. If you are asked to pay money to receive your prize, this is cause for concern.
Let’s say you receive an email that appears to be from Stake.us. In this case, you should check the email address that it came from. If you search the email address online, it should be attached to the website. If it does not bring up anything relating to Stake.us, you can be sure that you are dealing with a scam.
Scammers commonly misspell words on purpose, as it is a tactic to prey on the most vulnerable. Genuine and legitimate brands like Stake.us, McLuck, and WOW Vegas thoroughly proofread their emails, so while typos can get through, there will not be many.
You receive an email from what appears to be a legitimate sweepstakes casino – great! But you are pretty sure that you did not enter, and the email contains a link for you to click on and claim your prize. If this happens to you, make sure you verify where it has come from and do not click on any links that you are unsure of.
I can safely say that mail-in sweepstakes casinos are a breath of fresh air to any social gamer. Whether you are a casual player or a frequent gamer, mail-in bonuses are ideal for everyone. Let’s face it, who doesn’t like some free Sweeps Coins?
Mail-in bonuses come in all shapes and sizes, as you can see from my recommended sites Stake.us, McLuck, and WOW Vegas. The best value mail-in bonuses require minimal effort, just like the top sites on this page. If these sites have piqued your interest, check out our list of recommended mail-in promotions in this guide.
Unfortunately, if you do not include your return address, then your request will be disqualified. If the sweepstakes casino can’t work out where to send your letter, then it can’t be sent.
No, you are limited to sending one entry per envelope. However, many mail-in sweepstakes casinos permit you to enter as many times as you wish, provided that this is done separately.
Whether or not there is a limit will depend on your chosen mail-in sweepstakes casino. While some sites might have a limit of one entry, other sites permit unlimited entries.
Yes, generally speaking, the requirements will ask you to handwrite the postcard, postal addresses, etc. You will usually have to write this in black ink, but this rule will depend on your chosen sweepstakes casino.
