Download the OK37 app — Android & iOS
The OK37 app is the official way to play Aviator, Mines, Slots and 100+ games on your phone. This page walks you through the install on Android and iOS in Pakistan, and how to claim the Rs 37 welcome bonus via referral code 8MSWFK the moment you sign up.
About the OK37 app
OK37 is a real-money gaming app built specifically for players in Pakistan. The app carries 100+ games — Aviator, Mines, Slots, Live Casino, Blockchain, Fishing — and prices everything in PKR with local payment support. The Rs 37 welcome bonus you get via referral code 8MSWFK is real money credited automatically once you finish sign-up — not a credit you have to wager 50 times to unlock.
The app is the recommended way to play — it runs faster than the browser client, supports push notifications for round results, and remembers your login. The same account works across phone and web, so you never lose progress if you switch devices.
Install on Android (APK)
- 01
Open the official referral link
Tap the OK37 referral link from this page on your Android phone. It opens the official ok37.me download page — bookmark this URL, never trust APK aggregator sites.
- 02
Tap 'Download for Android'
The APK file (~50–80 MB) starts downloading. If your browser asks 'Keep dangerous file?' tap Keep — Chrome shows this warning for every APK outside the Play Store; it's expected.
- 03
Allow install from unknown sources
When you tap the downloaded APK, Android asks for permission to install from this browser. Tap Settings → enable 'Allow from this source' → go back. (You only do this once.)
- 04
Install and open the app
Tap Install. After ~20 seconds the app is ready. Tap Open, register a free account — code 8MSWFK pre-fills — and the Rs 37 welcome bonus drops into your wallet immediately.
Install on iOS (iPhone)
- 01
Open the referral link in Safari
Tap the OK37 referral link on your iPhone — make sure it opens in Safari (not Chrome or another browser). Safari is required for the iOS install flow.
- 02
Tap 'Get for iOS'
Safari opens an install prompt. Tap Install — iOS may ask you to confirm by opening Settings → General → VPN & Device Management → trust the OK37 profile. Standard for any non-App-Store install.
- 03
Wait for the icon to appear
The OK37 icon appears on your home screen and finishes installing. This usually takes under a minute on Wi-Fi. Don't close Safari until the icon shows the full app logo.
- 04
Open the app and sign up
Tap the OK37 icon. Code 8MSWFK pre-fills on the sign-up screen. Complete registration and the Rs 37 welcome bonus is credited instantly to your wallet.
Why use the app over the browser
Faster gameplay
Native rendering means Aviator rounds and slot reels animate at a higher frame rate than the browser. Cash-out taps register noticeably faster — critical on crash games.
Works on weaker connections
The app caches game assets locally, so unstable mobile internet doesn't kick you out of a round. The browser client has to re-fetch on every reload.
Secure account handling
The app stores your session token in the iOS Keychain / Android Keystore — not in cookies. Safer from session hijacking than a browser tab on a shared device.
Lightweight install
At ~60 MB the app is smaller than most social apps. It auto-updates in the background — you always have the latest game library without manually re-installing.
Only download OK37 from the official referral link. Random APK download sites often bundle malware with real-money gaming apps. If you ever lose the official link, navigate here from a search result for "ok37.online" — never trust unofficial mirrors. Players must be 18 or older.
Bonuses you get on first install
Installing the app and signing up with referral code 8MSWFK unlocks the full OK37 bonus stack right away:
- Rs 37 welcome bonus — credited the instant registration completes, usable on any game.
- Up to +300,000 PKR deposit bonus — applied automatically on your first deposit.

- Daily drops — 8 prize-pool events every day for active players.

App download FAQ
Is the OK37 app free to download?
Yes. The OK37 app is completely free to download on both Android and iOS. There is no signup fee, and the Rs 37 welcome bonus credited via referral code 8MSWFK is real money you can play with on any of the 100+ games.
Is the OK37 APK safe to install?
Yes — provided you download it from the official source. Always tap the referral link to reach the official OK37 download page; never install OK37 from a random APK site. The official app is signed and verified, runs on Android 6.0+ and iOS 13+, and does not request any permissions beyond what's needed for gameplay and account security.
Why isn't OK37 on the Google Play Store?
Google Play restricts most real-money gaming apps in markets like Pakistan due to its policy on gambling-style content. This is standard for the category — almost every casino-style app in the region distributes via direct download instead. The official OK37 APK is functionally identical to a Play Store install.
How big is the OK37 app?
The OK37 Android APK is roughly 50–80 MB and the iOS install is similar. On a modern phone over Wi-Fi it downloads in under a minute. The app then loads game assets on demand, so you don't need to download the entire game library upfront.
Do I enter the referral code 8MSWFK before or after installing?
After installing. Use the referral link to install the app — the code 8MSWFK is then pre-filled automatically when you reach the sign-up screen. The Rs 37 welcome bonus drops into your wallet the moment registration completes.
