Shared-device play
A game may let players take turns on one device or use the same screen together. Confirm the player count and how turns or controls work.
Wireless local play
Some games support nearby devices through Bluetooth or a local network. The exact setup depends on the title, devices and supported mode.
Local is not always offline
A local mode can still require an initial sign-in or server check. Test the full setup with your group before using it away from internet access.
Agree on the setup
Check versions, connection method, controls and how to leave the session. Keep invitations within the intended group.
