Someone rides the MRT tonight — and you may never see her coming. Hantu Line turns Singapore's MRT network into a game of hidden movement and pure deduction. Somewhere on the map, one player has become the Pontianak — the most feared hantu in Malay folklore — riding the rails invisibly. Everyone else plays TransCom, a five-officer squad codenamed Kopi, Teh, Milo, Bandung and Horlicks, working the same network to corner her before she disappears for good. Every game, choose your side: slip into the shadows as the Pontianak, or lead the TransCom squad on the hunt. Whichever side you don't take plays itself, at one of three AI strengths — Rookie, Regular or Inspector — so the challenge always matches you. The hunt runs 24 turns on the real Singapore MRT map, rendered in the official LTA line colours. The Pontianak moves by Single Trip, Shuttle Bus and Express Bus like everyone else — or by her own Black Ticket and secret Hantu Routes. Officers see only the kind of ticket she spent, never the line or direction, and have to shade the map turn by turn to close the net. She's force-revealed just three times, on turns 3, 13 and 24 — every other move is theirs to work out. A well-timed CCTV sweep can pin her exact station; a Blackout card can kill that sweep cold. A Double Move can put a full extra station between her and the squad. This is hidden-movement deduction, rebuilt from scratch around a map every Singaporean already carries in their head. • Real Singapore MRT network • Play either side — the hidden Pontianak or the 5-officer TransCom squad — every single game • Three AI difficulty levels: Rookie, Regular, Inspector • A deep ticket economy — Single Trip, Shuttle Bus, Express Bus, Black Ticket, secret Hantu Routes • CCTV sweeps, Blackout cards and Double Move keep both sides guessing until the last turn • Reveals on turns 3, 13 and 24 only — the map never hands her over for free • One-time purchase.
