Identify the mode
Read whether the game supports online rooms, nearby-device connections, same-screen play or taking turns on one device.
Agree on the setup
Check player counts, supported devices, versions and invitation methods. Practise joining and leaving before the planned session.
Local does not guarantee offline
Initial sign-in or server checks can still be required. Test the complete local setup if you plan to use it without internet.
Set the pace
Agree on breaks and keep invitations within the intended group. Use publisher support for connection or account problems.
