How to download and install the 1win APK on Android
1win's Android app is an APK from the official site for Android 5.0 and up; there is no Google Play listing for India and no App Store app, so iPhone users run the site as a web app. Installed, the app takes 30 to 35 MB and grows as it caches games.
- 1Open the official site through our link The link opens the registration window on 1win's current domain; close it for now and find the app section, usually a phone icon in the header or a link in the footer.
- 2Download the APK The installed app takes 30 to 35 MB; compare the size the page shows with the file in Downloads, and treat a file several times larger as not this app.
- 3Allow installs from the browser Open the file, allow the browser to install apps when Android asks, go back and tap Install.
- 4Register with code 3TREE Register inside the app: tap the + Promo code button in the form to reveal the hidden field, enter 3TREE, set the currency to INR and verify the phone. The first deposit activates the package.
The security warning during the install is routine for any app outside Google Play. What is not routine is a file from a forum, a file locker or a Telegram channel; those are how logins get stolen. Compare the size of the file you downloaded with the figure on the operator's page, and if the name contains mod, hack or unlocked, delete it.
1win on iPhone
There is no 1win app in the App Store for India. Open the site in Safari, tap the share icon and choose Add to Home Screen; the icon runs the site full screen and keeps the session. It carries every function of the Android app.
Welcome bonus in the 1win app, with code 3TREE
| Package | 500% across the first four deposits: 200%, 150%, 100% and 50% |
|---|---|
| Cap | ₹189,360 across the four deposits with code 3TREE |
| Minimum deposit | ₹300, by UPI, PhonePe, Google Pay or another rupee rail |
| Code | 3TREE in the registration form |
| How it is released | Bonus money sits in a separate wallet and cannot be withdrawn. Each winning single bet at odds 3.00 and up, placed from the real balance, transfers 5% of that bet's amount from the bonus wallet to the main balance |
| Time limit | 30 days from the first deposit for the whole package; no separate deadlines per part; whatever is left in the bonus wallet after 30 days is lost |
| Codes later | 3TREE works only in the registration form; codes for free bets and cash bonuses can be entered afterwards under Settings, Promo code |
Five hundred per cent sounds like the biggest offer on the site, and in a sense it is; in another it is the slowest. The bonus never lands on the main balance in one piece: it drips over, five per cent of each winning single bet at odds 3.00 and up placed from the real balance, which means a player who bets favourites at 1.50 releases nothing at all. That rewards a particular style, long shots and outsiders, and it means the useful number is not the ₹189,360 cap but the share you will actually release inside the 30 days the package lives; whatever is still in the bonus wallet on day 31 is gone. The four parts have no separate deadlines, so the clock starts at the first deposit for all of them.
500% up to ₹189,360, code 3TREE
The code goes into the registration form; a code added after the first deposit does not work. Bonus terms rotate, so read the version inside the account on the day you deposit.
Deposits and withdrawals
The cashier runs in rupees on an Indian account, with UPI and net banking up front and crypto behind them; deposits start at ₹300 for the bonus and withdrawals from about ₹500. Since the 2026 bank blocks the UPI transfers run through personal accounts that rotate, so save the UTR and a screenshot of every payment. Withdrawals go back through the deposit rail after KYC; our own withdrawals on 7 September 2026 landed in 10 to 30 minutes.
What is inside the 1win app
The casino is the front door: several thousand slots including the Pragmatic Play and PG Soft titles we review, Fortune Tiger among them, a live lobby with Dragon Tiger and teen patti, and 1win Games, the operator's own instant titles. The crash shelf carries the Spribe original Aviator and its siblings. The sportsbook behind covers cricket through the IPL and international calendar with live betting, plus 30 other sports.
Fake APKs, mirrors and safety
1win is one of the most cloned names in India: the search results for its app are mostly affiliate domains and APK stores, and a repackaged 1win APK from any of them is a way to lose the login. Download only from the official domain that our link opens, compare the file size with the page's figure, and check the footer names MFI Investments Limited. Under the block 1win runs mirrors of its own, and the footer plus a valid certificate is what separates a mirror from a clone.
- The footer names MFI Investments Limited and shows the Curaçao licence; a clone usually gets the company name wrong or drops it.
- The file came from the official domain and its size matches the figure on the page.
- You arrived by typing the address, from a bookmark or through a link on a site you trust, not from a message someone sent you.
- Nothing asks for a card number or a UPI PIN at login; the operator never does.
1win app vs the browser
The APK keeps the session and starts faster than the browser on a weak connection; the web app on iPhone does the same job. Bonuses, rails and limits are identical across all three.
Is the 1win app legal in India in 2026?
Real money online gaming is prohibited across India since 1 May 2026, when the Promotion and Regulation of Online Gaming Act, 2025 and its 2026 Rules came into force. The law targets operators, advertisers and payment channels rather than players, but a balance at an offshore operator has no legal protection and a dispute cannot be taken to an Indian regulator. 1win is licensed outside India. Set a deposit limit in the app before the first bet, keep the first deposit small, and read our responsible gaming page if it stops being fun. 18+.
