Sweepstakes Casino Washing: What It Is and the Real Math
Washing means playing your Sweeps Coins through the required playthrough, usually 1x, on low-volatility, high-RTP games so they become redeemable while you lose as little as possible. Players pair it with discounted coin packages. The expected cost is roughly coins × playthrough × house edge, but a bad run can still wipe out the balance.
Key facts
- Washing is playing low-volatility, high-RTP games purely to meet playthrough, turning unredeemable SC into redeemable SC (SweepsCoinTracker glossary).
- Most sweepstakes casinos require a 1x playthrough; Stake.us requires 3x on coins that didn't come from wins (Sweeps Kings, August 2026).
- Nine sweepstakes casinos tested by JustGamblers have a 10 SC minimum redemption (February 2026).
- JustGamblers measured average redemption times of 56 hours for crypto, 82 for gift cards and 95 for cash.
- Expected washing cost is about coins × playthrough × (1 − RTP): 100 SC at 1x on a 96% RTP game costs about 4 SC on average.
Hang around sweeps Discords long enough and someone will say they're "washing" a package. No, nobody's doing laundry. It's slang for getting Sweeps Coins through the playthrough so you can redeem them, while losing as little as you can on the way. This guide covers how it works, the math behind it, and where it goes wrong.
What washing means
Sweeps Coins don't start out redeemable. As the JustGamblers glossary puts it, playthrough is the set of conditions you have to meet to turn bonus Sweeps Coins into redeemable ones. At most sites that means playing every coin once (1x).
Washing is doing that playthrough on purpose, on the calmest games you can find. The SweepsCoinTracker glossary describes it as playing low-volatility, high-RTP games purely to meet playthrough, losing as little as possible. You're not chasing a big hit. You're trying to get the coins to the other side mostly intact.
How washing works, step by step
- Get Sweeps Coins: free ones (sign-up bonus, daily logins, mail-in requests) or the free SC that come bundled with a Gold Coin package.
- Check the playthrough. It's usually 1x. Stake.us is the well-known outlier: coins that didn't come from wins must be played three times (Sweeps Kings, August 2026).
- Pick a low-volatility game with a high RTP. Low volatility means smaller, more frequent wins, so your balance swings less. Check the RTP in the game's info screen, and check the terms for games that don't count toward playthrough.
- Play through at small bet sizes. Small bets relative to your balance keep one bad streak from ending the session.
- Redeem once you're over the minimum. Nine sites JustGamblers tested have a 10 SC minimum, and some set a higher one for cash than for gift cards.
The cashier usually shows how much is redeemable and how much is still unplayed, so you can watch your progress (Sweeps Kings).
The math
The house edge is 1 minus the game's RTP. On average, washing costs you:
coins × playthrough × (1 − RTP)
| You wash | Playthrough | Game RTP | Average cost | Average left to redeem |
|---|---|---|---|---|
| 100 SC | 1x | 96% | 4 SC | 96 SC |
| 100 SC | 1x | 98% | 2 SC | 98 SC |
| 100 SC | 3x | 96% | 12 SC | 88 SC |
| 20 SC | 1x | 96% | 0.8 SC | 19.2 SC |
These are averages over many sessions. A single session can end well above or at zero. The sweepstakes playthrough calculator shows the swing for your own balance. That's the whole reason washers pick low-volatility games: the same average with smaller swings.
When does a package make sense?
Washers mostly care about one number: what each Sweeps Coin cost them. Most sites treat 1 SC as about $1 in prize value. These are round example numbers, not any specific site's offer:
- Full-price package: pay $20, get 20 free SC with the Gold Coins. After washing you'd expect about 19.2 SC back. On average you're slightly behind, and the Gold Coins are the entertainment you paid for.
- Half-price first purchase: pay $10, get 20 SC. The same wash leaves about 19.2 SC on average. That gap between cost and value is what washers call profit, and it's why they hunt first-purchase deals.
- Free SC: cost $0. Anything you redeem is pure upside, though free amounts are small and slow to build.
The catch: the best discounts are usually one-time, first-purchase offers. Once you've used them at a site, the math goes back to the full-price line.
What can go wrong
- "Average cost 4 SC" can still mean losing 30 on a bad night. Averages only show up over many sessions.
- Multiple accounts, shared payment methods or promo abuse can get an account closed and winnings voided. Read the rules before chasing any deal.
- Your first redemption usually needs ID checks, so the first cash-out takes longer.
- Redemptions take time: JustGamblers measured averages of 56 hours for crypto redemptions, 82 for gift cards and 95 for cash.
- Sweepstakes casinos are banned in 14 states as of July 2026. Check the state list first. Or pick your state in the state checker.
- Redemptions are taxable income. Our sweepstakes tax calculator shows what to set aside.

Frequently asked questions
What does washing mean at a sweepstakes casino?
It means playing Sweeps Coins through the playthrough requirement on low-risk games, so they turn into redeemable coins while losing as little of the balance as possible.
Is washing allowed?
Playing your coins through is how every sweepstakes casino works, so the playthrough itself is normal. What gets accounts closed is breaking the terms around it, like multiple accounts or bonus abuse. Read each site's rules before you chase a promo.
Is washing profitable?
Only when the coins cost you less than they're worth, like with free SC or a deeply discounted first purchase. Even then it's an average, not a promise: variance can take your whole balance.
What games do people wash on?
Low-volatility games with a high RTP, because they swing less. Check each game's info screen for its RTP, and check the site's terms for games that don't count toward playthrough.
