The best Stake.us referral code is SPINDEX. Enter it during signup to claim $25 Stake Cash, 250,000 Gold Coins, and 3.5% instant lifetime rakeback on every future wager. No deposit required for the signup portion, and the rakeback never expires. Code must be entered during account registration - Stake.us does not allow referral codes to be added after signup.

A Stake.us referral code is a short text string entered during account registration that permanently links your account to a referring partner. When you sign up with a valid code, you unlock promotional perks that are not available on a blank signup - most importantly the welcome package and, for certain codes like SPINDEX, ongoing lifetime rakeback on every wager.
The code field appears at the bottom of the Stake.us signup form as "Promo Code" or "Referral Code." It is collapsed by default on mobile, so players often miss it and sign up without any bonus attached. The referral link on this page pre-fills SPINDEX automatically and opens the registration modal directly, so you never have to scroll for the field.
Referral codes, promo codes, bonus codes, signup codes, and affiliate codes are all names players use for the same thing on Stake.us. They all refer to this one field in registration. The difference between them is what each code actually pays out - some give only Gold Coins, some give only a one-time Stake Cash drop, and the best ones include recurring rakeback. SPINDEX gives all three.
The SPINDEX welcome package breaks into three pieces, delivered in different ways. Understanding how each one works tells you which part is actually worth the most.
Stake Cash is the sweepstakes currency. It is the only Stake.us currency that can be redeemed for cash prizes once you meet the playthrough requirement (1x wager on SC earned from promotions). Your $25 SC from SPINDEX is delivered to your balance as soon as you claim the welcome offer from the Promotions page.
Wager it through games once and you can redeem back to your bank account via ACH, Visa, or certain crypto rails. No deposit is needed to unlock this portion.
Gold Coins are the play-money currency. You can use them on every game in the Stake.us library but they cannot be redeemed for cash. Think of them as arcade tokens for extending your play time, grinding VIP points, or testing new games without touching your Stake Cash balance.
250,000 GC is enough to run roughly 250-2,500 spins on most slots depending on your bet size, which is substantial free entertainment time.
This is the piece that outlasts the signup bonus. Every time you wager on Stake.us with your account linked to SPINDEX, 3.5% of that wager is returned to you as Stake Cash, automatically, instantly. The rate never decreases. It does not expire. It applies forever.
Most Stake.us codes only give the sign up package. SPINDEX is one of the few that also includes rakeback, which is why it compounds into significantly more value over time.
All three pieces stack with every other Stake.us promotion - the daily login bonus, the Saturday weekly reload, the monthly reload, VIP rewards, and any cashier-based promo codes. SPINDEX never competes with another promotion; it sits underneath all of them.
Lifetime rakeback is the part of the SPINDEX offer most players underestimate. A one-time $25 signup bonus is finite. A 3.5% return on every future wager is not. Over time, the rakeback piece is where SPINDEX actually separates from the rest of the Stake.us code field.
Here is what 3.5% pays back at a few realistic wager volumes:
| Total wager volume | Rakeback earned (3.5%) |
|---|---|
| $500 | $17.50 SC |
| $2,500 | $87.50 SC |
| $10,000 | $350.00 SC |
| $50,000 | $1,750.00 SC |
The rakeback is credited instantly - you do not claim it, you do not wait for a weekly drop, you do not meet a threshold. After each wager resolves, the 3.5% slice appears in your SC balance. Because it is paid in Stake Cash, you only need to meet the standard 1x playthrough before it becomes redeemable.
3.5% also compounds on top of the Stake.us VIP tier system. The VIP program already pays out reload bonuses and rank rewards as you climb. SPINDEX adds 3.5% underneath. A Platinum-tier player pulling weekly and monthly reloads is still earning 3.5% on every wager from SPINDEX - neither side cancels the other.
If you want to estimate how the VIP reload and the SPINDEX rakeback stack for your own wager volume, the free Weekly Bonus Calculator and Monthly Bonus Calculator on Spindex break it down side by side.
Signup takes under two minutes if you have an email and a valid US address. Here is the full walkthrough:
Click through to Stake.us using the referral link - this auto-fills SPINDEX in the registration form so you cannot forget to enter it.
Open the registration modal. You can sign up with email or link an existing Google, Twitch, Facebook, or Line account - the referral code field still applies either way.
Fill in your account details. You must be 21 or older (18+ in some states) and located in an eligible US state. Stake.us verifies location before releasing real prize redemptions.
Scroll to the bottom of the form and expand the Promo Code or Referral Code section. Make sure SPINDEX appears there. If the field is empty, type it in exactly as shown - all caps, no spaces.
Click Register, then open the verification email Stake.us sends you and click the confirmation link. Your account is now active and SPINDEX is permanently attached.
Once verified, head to Promotions in the sidebar and claim the SPINDEX welcome package. The $25 Stake Cash and 250,000 Gold Coins hit your balance instantly. The 3.5% lifetime rakeback is already active.
Critical detail: the referral code field is collapsed by default on mobile signups. If you register manually without using the SPINDEX link, you must expand the Promo Code section and type the code yourself. Using the direct referral link skips this risk - SPINDEX is already in the field when the signup modal opens.
Every US sweepstakes casino runs on a dual-currency model, and Stake.us is no exception. Understanding the split matters because SPINDEX pays out in both currencies and the rakeback is paid strictly in SC.
Gold Coins (GC) are the play-money currency. They are free to acquire through the daily login bonus, the occasional site promotion, the SPINDEX welcome drop, and bundled with Stake Cash when you buy a coin package. You can wager GC on every game in the lobby but GC cannot be redeemed back into cash. It exists for entertainment and for grinding VIP points.
Stake Cash (SC) is the sweepstakes currency. It is what the US sweepstakes legal model allows to be redeemed for real cash prizes once you wager it through once (1x playthrough). You receive SC for free at signup from SPINDEX, as a free daily login drop, as rakeback from every wager, from weekly and monthly reloads, as part of VIP rewards, and bundled as a "free sweepstakes entry" when you purchase Gold Coin packages.
Because SC has real-world redemption value and GC does not, SC is effectively the only currency that matters for long-term play. SPINDEX is structured to maximize SC accumulation - the $25 initial drop, plus 3.5% of every wager coming back as SC forever.
This trips up a lot of US players. Stake.us and Stake.com share the Stake brand but they are structurally different platforms. Referral codes are not interchangeable between them. SPINDEX is a Stake.us code and works only on Stake.us.
| Feature | Stake.us | Stake.com |
|---|---|---|
| Player base | US players only | International (not US) |
| Currency | Gold Coins + Stake Cash | Real money crypto |
| Legal model | Sweepstakes | Licensed gambling |
| SPINDEX redeems | $25 SC + 250k GC + 3.5% rakeback | Does not apply - different site |
| Redeem prizes | Yes, for cash | Crypto payouts |
| Deposit required | No - SC + GC free at signup | Yes - real crypto deposit |
If you are a US player, Stake.us is the platform you can legally use. Stake.com does not accept US signups - it is the international real-money crypto casino aimed at the UK, AU, CA, EU, and LatAm markets. Using a VPN to sidestep that is against Stake.com's terms and risks account closure and forfeited funds.
The SPINDEX code is attached to the Stake.us affiliate program, which is entirely separate from Stake.com's. If you see a SPINDEX-style code being promoted for Stake.com, it is a different code - it will not give you the $25 SC, 250k GC, or 3.5% lifetime rakeback described on this page.
Stake.us is a legitimate sweepstakes casino operated by Sweepsteaks Limited, licensed to operate under US sweepstakes law rather than traditional gambling licensing. The model is identical to long-standing US sweepstakes operators like Chumba, LuckyLand, and Pulsz - two currencies, prize redemption against the sweepstakes currency, age and geography restrictions.
To sign up and use SPINDEX you must be 21 or older in most states (18+ in a handful). Stake.us verifies your age and location during signup and again when you request a prize redemption. Identity verification (KYC) is required before cashouts are released.
Restricted states where Stake.us is not available at time of publication: Washington, Idaho, Nevada, Kentucky, Michigan, and New York. If you are in any other state and meet the age requirement, SPINDEX works. State availability can change, so always confirm on the Stake.us registration page when you sign up.

The best Stake.us referral code is SPINDEX. Entering SPINDEX during signup unlocks $25 Stake Cash, 250,000 Gold Coins, and 3.5% instant lifetime rakeback on every future wager. The rakeback is the most valuable piece because it compounds forever - most other Stake.us codes only give a one-time sign up bonus.
Go to Stake.us, click Sign Up, and look for the referral code or promo code field at the bottom of the registration form. Enter SPINDEX before submitting. The code must be entered during registration - Stake.us does not allow referral codes to be added to an account after signup is complete.
Code SPINDEX unlocks a three-part welcome package: $25 Stake Cash (the redeemable sweepstakes currency), 250,000 Gold Coins (the play-money currency), and 3.5% instant lifetime rakeback credited to your account on every wager you place, forever. You can claim the sign up portion immediately after registration without a deposit.
Lifetime rakeback is a percentage of every wager you place that gets returned to you as instant Stake Cash, credited automatically after each bet. The SPINDEX 3.5% rate applies forever - it does not expire, does not require opt-in, and stacks on top of every other Stake.us promotion including the weekly and monthly reload bonuses and the VIP program. On a $1,000 total wager volume you receive roughly $35 back in Stake Cash.
Yes. Stake.us operates as a sweepstakes casino and is legally available in most US states. It is not a real-money casino - you play with Gold Coins (free, for fun) and Stake Cash (promotional sweepstakes currency that can be redeemed for real cash prizes once you meet the playthrough requirement). Stake.us is owned by Sweepsteaks Limited and operates under US sweepstakes law, which is why it is accessible in states where traditional online casinos are not.
Stake.us is available in most US states. Restricted states currently include Washington, Idaho, Nevada, Kentucky, Michigan, and New York. If you live in any other state and are 21 or older (18+ in some states), you can use SPINDEX at signup. Always check the current terms at Stake.us during registration because state availability can change.
Stake.us is the US sweepstakes casino for American players - it uses Gold Coins and Stake Cash and is legal in most US states. Stake.com is the international real-money crypto casino, which is not available to US players. Referral codes do not transfer between them. For US players, SPINDEX is the code for Stake.us specifically.
No. The SPINDEX welcome package ($25 Stake Cash + 250,000 Gold Coins) is delivered without any deposit requirement. The 3.5% lifetime rakeback kicks in automatically once your account is created with the code attached. You only need to make a purchase if you want to buy additional Gold Coin packages, which come bundled with Stake Cash.
Stake.us locks the referral code at account creation. If you already signed up without a code, contact Stake.us support and request SPINDEX be attached manually - some players have had success with this for recently-created accounts, but success is not guaranteed. If support declines and you want the lifetime rakeback, the clean route is to close the account and re-register using SPINDEX during signup.
Yes. Stake.us runs a VIP tier system with weekly and monthly Stake Cash reload bonuses that scale with your level. The 3.5% SPINDEX rakeback is separate from the VIP program - you collect both. Spindex has a free Stake.us VIP Calculator and Weekly and Monthly Bonus Calculators that show your expected reload amounts based on your tier and wager volume.
Yes. Referral codes on Stake.us are free. Entering SPINDEX costs nothing and does not affect your account balance. It simply tags your account so the sign up bonus and the 3.5% lifetime rakeback are applied correctly.
Referral codes on Stake.us are one-per-account and are locked at signup - you cannot stack multiple referral codes. However, SPINDEX stacks with every other Stake.us promotion: the daily login bonus, weekly and monthly reloads, VIP rewards, and time-limited promo codes released in the cashier. The 3.5% rakeback applies on top of all of them.
