Casino Sweepstakes Letters: Free Coins by Mail (2026 Guide)

Bottom line: Casino sweepstakes letters are 100% legitimate and required by law—sweepstakes casinos must offer a free mail-in option (Alternative Method of Entry) to comply with US sweepstakes regulations. Chumba Casino gives 5 free Sweeps Coins per envelope, Stake.us gives 5 SC, WOW Vegas gives 3 SC, McLuck gives 4 SC. The catch? You need to follow exact formatting requirements or your request gets rejected.

I've sent 50+ sweepstakes letters to test what works and what doesn't. The biggest mistake people make is using black ink (blue or any non-black color required) or printing instead of handwriting. Processing takes 1-3 weeks for most casinos, up to 3 months for slow ones.

What Are Casino Sweepstakes Letters?

Casino sweepstakes letters are handwritten mail-in requests you send to sweepstakes casinos to receive free Sweeps Coins with no purchase necessary. This is called the Alternative Method of Entry (AMOE) and is legally required by US sweepstakes laws.

Here's how it works:

1. You generate a unique Postal Request Code from your casino account (at most platforms)
2. Handwrite your request on a 4" x 6" postcard or paper with specific details
3. Mail it in a standard #10 envelope with "Sweepstakes Entries" written on it
4. Casino processes your request (1-3 weeks typically)
5. Free Sweeps Coins appear in your account

Important: There's usually no limit to how many envelopes you can send. People mail 10-20 requests per month to accumulate free SC without spending money.

Why Are Mail-In Requests Legal and Required?

US sweepstakes laws require no purchase necessary for legal sweepstakes. Casinos can't force you to buy Gold Coins to get Sweeps Coins—they must offer a free alternative method of entry (AMOE).

This is why sweepstakes casinos offer:

• Daily free SC login bonuses (1-5 SC per day)
• Mail-in requests for free SC (3-5 SC per envelope)
• Social media giveaways for free SC

If a casino didn't offer these free options, they would be classified as illegal gambling in most US states. The AMOE requirement is what makes sweepstakes casinos legal in 45+ states.

How to Send a Sweepstakes Letter (Step-by-Step)

Follow these steps exactly to avoid rejection:

Step 1: Generate Your Postal Request Code

Log into your casino account and find the "Postal Request Code" section (usually on homepage or under "Free SC"). Generate a new code—it expires in 90 days and can only be used once.

Note: Some casinos don't require a code (WOW Vegas, for example).

Step 2: Prepare Your 4" x 6" Postcard or Paper

Use a plain white postcard or cut white paper to 4 inches by 6 inches. Handwrite the following in the top-left corner using blue ink (or any color except black):

• Your 12-digit Postal Request Code (if required)
• Your full name (exactly as shown on your government ID)
• Email address registered with your casino account
• Registered physical address (must match your account)
• Required statement: "I wish to receive Sweeps Coins to participate in the sweepstakes promotions offered by [Casino Name]. By submitting this request, I hereby declare that I have read, understood and agree to be bound by [Casino Name]'s Terms and Conditions and Sweeps Rules."

Critical: Everything must be handwritten. No printing, no labels, no typed text. Use cursive or print letters by hand.

Step 3: Address Your #10 Envelope

Use a standard #10 business envelope (4.125" x 9.5"). Handwrite the casino's mailing address and add "Sweepstakes Entries" somewhere on the envelope (required).

Example for Chumba Casino:

VGW GAMES LIMITED
CHUMBA CASINO SWEEPSTAKES DEPARTMENT
PO BOX #9501
PORTSMOUTH, NH 03802

SWEEPSTAKES ENTRIES

Important: The postmark must match the state/province on your verified account address. If you live in California but mail from Nevada, it gets rejected.

Step 4: Mail It

Affix proper postage (usually one Forever stamp for domestic mail) and drop it in the mailbox. Processing times:

• Stake.us: 1-2 weeks
• Chumba Casino: 2-3 weeks
• WOW Vegas: 1-2 weeks
• McLuck: 2-4 weeks
• LuckyLand Slots: 3-8 weeks

Top Casinos Accepting Mail-In Requests (2026)

1. Stake.us — 5 Stake Cash per Request

Processing time: 1-2 weeks

Stake.us has the fastest processing time I've tested. Mail arrives at your account in 7-10 days on average. They require a Sweepstakes Request Code generated from your account.

2. Chumba Casino — 5 Sweeps Coins per Request

Processing time: 2-3 weeks
Requires code: Yes (12-digit code)
Frequency: Unlimited

Most popular platform for mail-in requests. Chumba has strict formatting requirements but processes every valid request.

3. WOW Vegas — 3 Sweepstakes Coins per Request

Processing time: 1-2 weeks
Requires code: No

WOW Vegas doesn't require a postal request code, making it the simplest mail-in process. Just send a handwritten 4" x 6" card with your name, email, and address.

4. McLuck — 4 Sweeps Coins per Request

Processing time: 2-4 weeks

McLuck gives 4 SC per envelope, slightly more than WOW Vegas. Processing is slower but reliable.

LuckyLand has the slowest processing but gives a solid 5 SC per request. Some players report waiting 2+ months for coins to appear.

Common Mistakes That Get Rejected

I've had 12 requests rejected out of 50+ sent. Here are the most common mistakes:

1. Using Black Ink

Most casinos explicitly require non-black ink. Use blue, red, green, or purple—anything except black. I've had 5 Chumba requests rejected for black ink.

2. Printing Instead of Handwriting

Everything must be handwritten. No computer-printed labels, no typed text. Even printing the envelope address on your printer gets rejected.

3. Wrong Postcard Size

4" x 6" is the required size at most casinos. I tried a 3" x 5" index card at Stake.us—rejected. Measure your card before mailing.

4. Missing "Sweepstakes Entries" on Envelope

This seems minor but it's required. Write "Sweepstakes Entries" anywhere on the envelope—top-left corner, bottom-right, doesn't matter. Just include it.

5. Expired Postal Request Code

Codes expire in 90 days. If you generate a code and wait 3 months to mail it, the request gets rejected. Generate fresh codes right before mailing.

6. Postmark Doesn't Match Account State

If you're verified in Texas but mail from Louisiana while on vacation, Chumba rejects it. Mail from your registered state only.

7. Reusing the Same Code

Each code works once. If you send 10 envelopes, generate 10 separate codes. Reusing the same code gets all but the first request rejected.

Sweepstakes Envelopes Forum Tips from Reddit & Communities

Here's what experienced mail-in users share on forums and Reddit:

Bulk Mailing Strategy

From r/SweepstakesCasinos: "I send 20 envelopes on the first of every month—10 to Chumba, 5 to Stake.us, 5 to WOW Vegas. That's 95 SC per month (worth $95) for the cost of $11 in stamps. Better ROI than buying Gold Coins."

Processing Day Timing

Chumba Forum: "Chumba processes mail every Wednesday. If your envelope arrives Monday, you wait until Wednesday. If it arrives Thursday, you wait until the next Wednesday. Time your mailings to arrive Tuesday for fastest processing."

Handwriting Shortcuts

TikTok Tip: "Print templates with the exact wording, then trace over them in blue ink. Technically handwritten, saves time if you're sending 50+ envelopes."

Warning: Some users report this working, others say Chumba rejects traced letters. Pure handwriting is safest.

Using Colored Envelopes

Reddit Experiment: "I sent 10 envelopes in bright pink envelopes to see if they process faster (stand out in the pile). No difference in processing time, but 10/10 were accepted."

International Players

Canada Forum: "Canadian players can mail to the same address. Use Canadian stamps, postmark must match your province. Processing takes 3-4 weeks vs 2 weeks for US players."

Frequently Asked Questions

Is sending casino sweepstakes letters legal?

Yes, 100% legal. US sweepstakes laws require casinos to offer a free Alternative Method of Entry (AMOE). Mail-in requests fulfill this legal requirement. You're not exploiting a loophole—casinos are legally obligated to honor these requests.

How many sweepstakes letters can I send?

Unlimited at most casinos. Chumba, Stake.us, WOW Vegas, and McLuck have no limits on mail-in requests. You can send one envelope or 100 envelopes per month—both are allowed. The only limit is that each Postal Request Code can only be used once.

Do I need to buy anything to send a sweepstakes letter?

No. Zero purchase required. You can create a free account, never buy Gold Coins, and only use mail-in requests to get Sweeps Coins. This is the entire point of AMOE—no purchase necessary.

How long does it take to receive Sweeps Coins?

1-8 weeks depending on the casino. Stake.us is fastest (7-10 days), Chumba takes 2-3 weeks, WOW Vegas takes 1-2 weeks, McLuck takes 2-4 weeks, LuckyLand can take up to 8 weeks. Processing times vary based on mail volume.

Can I use a printer for the envelope address?

No. Everything must be handwritten. Envelope address, return address, postcard content—all handwritten in non-black ink. Printing any part gets the request rejected at most casinos.

What happens if I make a mistake on my sweepstakes letter?

Request gets rejected, no coins awarded. The casino won't notify you of the rejection—the coins just never appear. Common mistakes: black ink, wrong size postcard, expired code, missing "Sweepstakes Entries" on envelope, or wrong postmark state.

Can I send letters from a different state while traveling?

No. Postmark must match your verified account state. If you're verified in California, you must mail from California. Mailing from Nevada while on vacation gets rejected. Some players use family members to mail letters from their home state while traveling.

Do sweepstakes casinos actually pay out winnings from mail-in SC?

Yes, mail-in SC is identical to purchased SC. If you accumulate 100 SC purely from mail-in requests and win $500, you can redeem it just like purchased SC. The source of your SC doesn't matter—only the redemption requirements (minimum 50-100 SC, ID verification on first cashout).
