Plenty of players assume the Casushi app has a mind of its own when the lobby flips sideways mid-spin. It does not. The app is simply obeying iOS, and iOS rotates whenever the device does unless you tell it otherwise. The fix takes about four seconds and lives in Control Centre, not in the Casushi settings menu. Here is the exact sequence, plus the caveats worth knowing before you blame the software.
Why the Casushi lobby keeps flipping sideways
The first myth to kill is that Casushi ships a rogue orientation setting. It does not. On iPhone and iPad, screen rotation is a system-level behaviour controlled by iOS, and the Casushi iPhone experience follows whatever the operating system allows. If your phone is unlocked from portrait lock, the lobby will rotate the moment you tilt the handset. That is standard behaviour across nearly every mobile casino app, not a bug specific to this one.
The second myth is that the Casushi mobile site behaves the same way. It does not, at least not identically. The responsive site detects screen dimensions automatically and reflows its layout to fit, so a sideways phone on Chrome for Android produces a wider lobby rather than a broken one. Neither approach is wrong. They are just different mechanisms, and only the native app on Apple hardware gives you a hard portrait lock through the operating system.
Worth stating plainly for anyone hunting downloads: Casushi does not publish a standalone Android APK file. Android users access the Casushi site through a mobile browser, and the shortcut you add to your home screen is a bookmark, not an installed package. Any site offering a Casushi casino app APK is not official, and you should close the tab. Apple users, by contrast, download the Casushi app from the App Store, which is the only legitimate source for the iOS build.
Locking portrait orientation in four steps
This is the whole procedure. It assumes the Casushi app is already installed and you are signed in. If you have not set up the app yet, do that first, then come back.
- Open the Casushi app from your home screen and let the mobile lobby load. You want the app in the foreground, not minimised, so you can see the result of the change immediately.
- Access Control Centre. On a Face ID iPhone, swipe down from the top right corner of the screen. On older handsets with a home button, swipe up from the bottom edge. The panel slides over the lobby.
- Enable portrait orientation lock. Tap the padlock icon with the circular arrow around it. It highlights when active. This is the single toggle that stops the lobby rotating, and it applies to every app until you switch it off.
- Verify by rotating your device. Turn the phone ninety degrees and hold it. The lobby should stay upright. If it still rotates, the lock did not register, so tap it again and repeat the rotation test.
That is it. No app restart, no reinstall, no support ticket. The mobile lobby now stays in portrait, which is the layout it was designed around: thumb-reachable buttons, a single-column game grid, and a cashier you can operate one-handed on the train. Landscape mode is not broken, but it is not the intended shape of the product either.
What the lock does and does not cover
The portrait lock is a device-wide setting, so it also pins your messages, your browser, and everything else until you disable it. That surprises people who expect an app-specific toggle. iOS does not offer one, and neither does the Casushi app, because Apple does not expose that level of control to third-party developers. If you want rotation back for video or a document, swipe into Control Centre and tap the padlock off.
One more caveat for iPad owners. Some iPad models handle multitasking and Stage Manager differently, and the lock behaves inconsistently when an app is running in a split-screen window. https://casushi-online.uk/app/ offers additional context worth reviewing. If the lobby refuses to stay put on an iPad, close the split view and run Casushi full screen before trying the lock again.
Related settings that keep the lobby stable
Orientation is the main culprit, but two other settings cause similar complaints. The first is Display Zoom. If you have enlarged text or switched to a zoomed display, the lobby can look cropped rather than rotated, and players often misdiagnose it as an orientation fault. Check Settings, then Display and Brightness, and confirm you are on the standard view before blaming the app.
The second is the login method. The Casushi app supports Face ID logins, and an interrupted Face ID prompt during a rotation can leave the screen in an odd state that looks like a stuck layout. If the lobby freezes rather than rotates, lock and unlock the phone once and authenticate again. It clears the glitch faster than force-quitting the app.
Push notifications are worth a mention too, since they interact with the lock in a small way. A notification banner arriving while the phone is held sideways can briefly rotate the preview, which reads as the app flipping. It is not. The lobby behind the banner has not moved.
Finally, remember where the money side lives. The Casushi app cashier manages payments inside the same portrait interface, so a stable screen matters more there than anywhere else. Deposits and withdrawals are the last place you want a mis-tap, and a locked orientation removes one variable from that process. The mobile lobby includes the welcome offer and the cashier in the same layout, so the lock covers everything that counts.
If you play through the browser instead, the Casushi mobile site offers responsible play tools alongside the games, including deposit limits and session reminders. Set those up regardless of how you access the lobby. A screen that stays upright is convenient; a budget that stays intact is the point.
For clarity on what this page is: this website operates as an information page only. It does not host games, take deposits, or process account details. Everything above describes settings on your own device and the behaviour of the Casushi app as published on the App Store. If a step does not match what you see, your iOS version has probably moved a toggle, and the Apple support pages will show the current position.
Run the four steps once and the problem is solved for good: open the Casushi app, pull up Control Centre, tap the portrait lock, then rotate the phone to prove it worked. Keep the padlock on during play and switch it off when you are done. If the lobby still spins after a verified lock, the cause is almost certainly a zoomed display setting or a split-screen window, not the app itself. Fix those two and you will not think about orientation again.
