One link. One room code. The software runs the session — the teacher leads the room, students make their own cards on any device or on paper.
Lead the room
Teacher / Site Lead. Project this screen. Every island is a session. Walk to today's island (arrow keys or the thumb pad), or tap its sign, and press Lead to get the room code.
← → to walk · tap a sign to fly there
Join with a code
Students. Type the code on the board.
No accounts. Nothing typed on a student's device leaves that device. Cards are printed, screenshotted, or copied by hand onto the paper version.
