Most sweepstakes-casino bonus code pages resolve the same way: no code exists, the free grant is automatic, end of story. McLuck is a partial exception. There is a real field at registration, labeled “Referred By,” and McLuck's own blog does publish codes for it from time to time. What that field actually changes, and what it doesn't, is the useful part of this answer.

The Free Grant Doesn't Need a Code

New McLuck accounts get 7,500 Gold Coins and 2.5 free Sweeps Coins automatically after signup and identity verification clears — no code, no referral field, no purchase. That's the baseline no-purchase entry every sweepstakes casino has to offer to stay inside sweepstakes law rather than gambling law, and McLuck pays it out the same way regardless of what, if anything, gets typed into the “Referred By” field during registration.

What the “Referred By” field is for: It ties a new account to a referral source or a specific promotional code, most often one published on McLuck's own blog. Recent examples reported there include MCLUCKBLOG26, attached to a discounted first Gold Coin purchase, and MCLUCKBDAY26, a birthday-specific offer. These rotate — a code that worked in August is not guaranteed to work in September.

Why the First-Purchase Numbers Don't Match Across Sites

Search “McLuck bonus code” and the first-purchase figures scatter: a $9.99 package for 120,000 Gold Coins plus 60 Sweeps Coins shows up on some sites, a $29.99 package quoted anywhere from roughly 62.5 up to 500 Sweeps Coins on others. That's not one site being wrong — it's the same pattern seen across sweepstakes casinos generally, where the headline package size tracks the specific tracked link or code a reviewer used rather than one fixed universal offer. The free 7,500 GC / 2.5 SC grant is the one number that holds steady across sources, because it doesn't depend on a link or a code at all.

Where to Check the Live Offer

McLuck's own promo-codes page at blog.mcluck.com and the in-app promotions tab are the two places an actually current code will show up. A code sitting on a third-party aggregator with no publish date, or a date several months old, is worth treating as stale rather than assuming it still redeems — the same caution that applies to any rotating sweepstakes-casino offer.

Who This Actually Matters For

  • Just want the free Sweeps Coins: skip the code hunt entirely — signup and verification alone trigger the 7,500 GC / 2.5 SC grant.
  • Planning a first Gold Coin purchase: check blog.mcluck.com or the in-app promotions tab first; a live code in the “Referred By” field can add bonus Sweeps Coins to that specific purchase.
  • Found a code on a random review site: confirm it against McLuck's own blog before counting on it — unofficial listings drift out of date the same way they do for every sweepstakes-casino brand.
