About #=#=#=#=#=#=#=#=#=# page.title is a genre designed by @portponky: as an omnipotent city planner, you strive for an harmonious subway network to keep your beloved citizens safe and mobile, while preserving precious parks and gardens. The earlier genre [Metro|https://puzsq.logicpuzzle.app/?kind=265] by Yusuke Yamamoto -- Puzzle Communication Nikoli vol.164 (2018-09) shares some similarities with page.title, albeit coincidental -- thanks @Wando! page.title Gallery #=#=#=#=#=#=#=#=#=# @Portponky's Originals ======================= These page.title puzzles have been created by @Portponky, upon inventing the genre. Later, a couple non-uniquenesses were corrected.
