Penthouse 13
An atmospheric hotel mystery
Only for iPhone

A locked penthouse. A name erased from the guestbook. Follow the clues through a hotel that has been waiting for you to return.
The receptionist gives you a key without asking your name.
“Penthouse thirteen. As always.”
You have never been here before. But when you wake, the door is locked from the outside, and a suitcase you do not recognise is waiting beside the bed.
Above the city roofs, an old hotel is keeping its last guests. Its quiet rooms hold fragments of the same night: a torn photograph, a name scratched from a ledger, a story someone took care to change.
Search the penthouse and follow the clues beyond its door. Collect objects, combine what belongs together and return to details that take on a different meaning as the truth emerges. Your journal keeps the discoveries close.
Thirteen puzzles lead you through six chapters, from the upper landing and deserted reception to the guest archive and the machinery beneath the hotel. Reassemble a photograph, uncover invisible ink and piece together the night the hotel refuses to forget.
Take your time. There is no combat or countdown. Optional hints offer a gentle nudge first, with clearer help only when you ask for it. Every essential clue can be read or seen.
Illustrated rooms, warm lamplight and deep shadows set the scene. Rain and distant thunder give way to quieter corners of the hotel — and something waiting for morning.
