There's a new WhatsApp invitation feature!
Events
Part of the July 9, 2026 update is a feature for inviting friends from WhatsApp!
Tap Add Friend > Create an invitation 2D code > OK, and you'll see the WhatsApp invitation button. Tapping the WhatsApp button will open WhatsApp, allowing you to send STRIKE WORLD invitation messages to your friends!
When you invite a friend, you'll both receive gems, so try inviting a bunch of people!
(You can receive gems for up to 10 friend invitations.)
