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!

@Portponky's Originals
=======================
These page.title puzzles have been created by @Portponky, upon inventing the genre. Later, a couple non-uniquenesses were corrected.

## Variants

Quarter Parks Variant
=====================
These puzzles make use of the internal "quarter park" representation, for an extra challenge.

### ´´turning´´
V=turning

The loop must turn at turning rings.

Known issues
#=#=#=#=#=#=#=#=#=#

For self-reference:
- ~~Adding parks is currently impractical, as each requires 4 different pieces.~~
- ~~Sub-pieces mess up board rotation.~~
- ~~In case a station touches a park, it must be added by editing the URL, otherwise the park will be erased.~~
- ~~The checker does not distinguish two independent loops crossing vs a single one, so some invalid solutions are marked as valid.~~
- ~~Gray solid lines may need to be changed.~~
- ~~Stations should always be on top of parks, not the other way around.~~
- ~~Stationless not yet allowed~~ (@karoo)
- ~~Quarter parks not error checked~~
- Metadata - dates: many date formats are not yet understood
- Metadata - sometimes we lose focus when editing, which is annoying
- ~~Parks are imprecisely placed  (@menderbug, Lukas)~~
- ~~Refresh bug (@hempuli)~~
- ~~Half station error checking fails for adjacent perpendicular track below/to the left.~~	


Ideas

For self-reference:
- ~~Shrink and fuse parks for better understandability~~ @deusovi
- ~~Half-parks~~ @dohz
- ~~Mid/diagonal-parks @@ dohz, portponky @@~~
- Variegating partial track colours (hue/lightness) or dashing, prior to fusing into a single track (@menderbug)
- Rivers - the track can cross them, but not change direction (@portponky) (part of the inital plan for subway)
- Parks on top of segments @TJCGames, possibly the same as the triangular park suggestion by ${"BoredMatt"}
