Please note that these are general instructions that should work for most Android devices. However, your device's interface may differ slightly depending on which Android version your device is running on, so these instructions may not match the exact headings on your device.

For iPhone X and later models, as well as iPads running on iOS 12 or a later iOS:
1. Swipe up from the bottom of the Home screen.
2. Swipe left or right until you find the app you want to quit.
3. Swipe the application preview up to force quit it.

For iPhone 8 and older versions:
1. Press the Home button twice to see the list of applications you've recently launched.

Windows

To close the app using a PC, all you need is to move the cursor to the upper right corner of the screen and click the X icon that appears there.

If you’re using a touchscreen device, just make a swipe from the top of the screen – the button to close the application should appear at the top of the screen.
You can also swipe from left to right: all the open applications will be displayed in the task window and you’ll be able to close the game.
