Lines 1–9, Suin–Bundang, Gyeongchun, Gyeongui–Jungang, AREX and Gimpo Goldline. Includes the Seoul Station, Imjingang and limited Gwangun Univ. branches. Other lines, ITX services, Dorasan and future extensions are excluded. Transfers count once; the two Sinchon stations and two Yangpyeong stations are separate places. The map uses real locations with simplified station-to-station connections, not every service stopping pattern. Optional strips show quiz order, not geography.
Web preview: refreshing this page resets the round. City quiz results do not change your logic puzzle score.
Sources and map notes
Station names and branches checked against Seoul Metro Cyber Station in Korean and English on 11 September 2026. Geography: OpenStreetMap contributors, adapted under ODbL 1.0, with 18 station coordinates from Wikidata (CC0). Transfer platforms are merged into one quiz point. Same-name Sinchon and Yangpyeong stations remain separate locations. Regional labels and river widths are illustrative; no official affiliation or journey-planning guarantee.
Both current and selected common older names are accepted, including Bulamsan / Danggogae and Jayang / Ttukseom Resort. The adapted data is available from the map credit. No live tiles or location tracking.

How to play Tower View
Use each height from 1 to the grid size once in every row and column.
An edge clue counts the towers visible from that side. Taller towers hide shorter ones behind them.
Starting numbers are fixed. A dot means no clue. Fill the grid to match every given view.
A quick example
From the left, 2, 1, 4, 3 shows two towers: 2 and 4. The edge clue is 2.
Where to start
A clue of 1 puts the tallest tower at the front. Start with Gentle 4×4 boards, then try 5×5 or fewer clues. Every puzzle has one solution. Progress lasts only while the puzzle stays open.
