MAXWIN100S links your account to the 500% welcome offer — a package spread across your first four deposits, up to about $2,000 in total. You type it in once, on the 1win sign-up screen, and from then on your first deposit qualifies. No code, no offer — it's that simple. Below I'll explain what the code unlocks and the exact box it goes in, why signing up without it shuts you out, and how the reward splits between the sportsbook and the casino. This is an independent guide. I don't take bets or hold any money, and I keep responsible-play limits front and centre. 18+.
How the 1win promo code works
MAXWIN100S has one job: it switches on the 500% welcome bonus on a new account. Enter it at sign-up and your first deposits qualify. Put that money on the sportsbook and the 500% package builds across your first four deposits, up to about $2,000 in total (600% if you deposit with crypto). Put it on the casino and you get the package plus 70 free spins. The code doesn't change the wagering at all — it stays x5 on accumulators: three or more legs, odds from 1.40, and a 30-day window. All the code does is put the bonus within reach.
How to enter the promo code
Start a new account
Open the 1win app (com.mobile.one_win, version 1.5.1) or the website and head to the sign-up form.
Choose a sign-up method
One-click, phone, email, or a social login. Whichever one you pick, the promo-code box is on the same form.
Set currency and details
Pick your account currency and fill in whatever your sign-up method asks for.
Enter the code
Type MAXWIN100S into the promo-code box on that same form.
Finish sign-up
Submit the form. Your account is now lined up for the welcome bonus — it just needs a qualifying first deposit of at least $5 (or the local equivalent).
Why you can't add the code later
Sportsbook vs casino
Once the code is in, where you send your first deposit decides what you get. Here's what each route gives you.
| Element | Sports path | Casino path |
|---|---|---|
| Bonus type | 500% package across your first four deposits | Deposit package with 70 free spins |
| Maximum value | Up to about $2,000 total (600% with crypto) | Up to about $2,000 total |
| Free spins | None on this route | 70 free spins |
| Qualifying deposit | $5 (or the local equivalent) | $5 (or the local equivalent) |
| Wagering | x5 on accumulators, 3+ legs, odds 1.40+, 30 days | Set by the casino terms |
How to deposit
With the code on your account, a first deposit of at least $5 (or the local equivalent) turns the offer on. 1win uses local payment methods in every country. In Bangladeshi taka, that's bKash, Nagad and Rocket. In Indian rupees, it's UPI, Paytm and PhonePe. In Pakistani rupees, JazzCash and Easypaisa. In Philippine pesos, GCash. In Kenyan and Tanzanian shillings, M-Pesa. And MTN MoMo covers several African currencies. You can also deposit with crypto — Bitcoin (BTC), Ethereum (ETH) or USDT (Tether). Withdrawals start from $10 (or the local equivalent), shown in the cashier. The full deposit walkthrough sits outside this independent guide.
