There are a few different ways that you can share your game videos with your friends on Yo WhatsApp. One way is to simply record your gameplay using a screen recording app, and then export the video file to your device. Another way is to use a dedicated game capture card, which will allow you to record your gameplay and then share it directly to YO WhatsApp.
If you want to share your game videos with as many people as possible, then uploading them to YouTube or another social media platform is a good option. You can then share the link to your video on Yo WhatsApp and anyone who clicks on it will be able to watch it.
Finally, if you're just looking to share a short clip of your gameplay with a friend or two, then you can use the built-in recording feature in some games to capture a short video and then share it directly to Yo WhatsApp.
