A teleporter ignores walls, and the outer edge is no more than a wall to it: a line leaving the maze at any square's edge re-enters at the opposite edge on the same row or column, one space on. The lettered openings connect as they always did. Older games crossed the edge only at the openings, and replay so; U3U2, dealt at rev 21 with no teleport yet cast, was re-stamped to 22 at its table's request.
