Ghost Signal: Phone Mystery

Ghost Signal: Phone Mystery

You stumble onto someone's phone. And from the other side of it, a voice is calling you.

About the game

Ghost Signal is a mobile cozy mystery game where the entire story unfolds inside a phone.

Late one night, your aunt calls out of nowhere — "Mina is gone. Can you help?"

Your cousin Mina has disappeared, and your aunt says you're the only one who can help. You gain remote access to her phone. Trace the truth through her messages, photos, voice memos, notes, social media — every trace on her phone. And at some point, you'll catch a ghost's signal, asking you for help.

Solve the case, and a new request will land in your anonymous SNS channel @ghostsignal_anon. The phones of strangers you've never met. The last traces they left behind. The cases keep coming.

The core fun

▷ Phone OS theme switching
The moment you switch from your phone to a client's phone, the screen fully boots into a completely different OS. A high schooler's lavender-toned phone, a salaryman's dark workspace, a streamer's neon RGB phone — the whole world shifts based on whose phone you're looking at.

▷ Ghosts aren't the enemy
No jumpscares. No graphic horror. Ghosts are simply people waiting for someone to listen to their story. The warm cozy mystery tone stays from start to finish.

▷ Every phone feature is a clue
Messenger, gallery, voice memos, calendar, notes, social, browser, call log — every real-phone app holds clues. Crack a lockscreen, find a hidden figure in a photo, hear the faint whisper in a voice memo, reconstruct a case from scattered clues. No system pop-ups, no narrator — the story only flows through the phone's own natural features.

▷ Ghost Hunter SNS channel
After you solve your first case, you open an anonymous SNS channel — @ghostsignal_anon. From that moment, new DMs asking for help never stop coming in. When one case ends, the next one is already starting somewhere else.

▷ 7 languages supported
Korean · English · Japanese · Chinese (Simplified/Traditional) · Spanish · Portuguese. The same experience in every language. Professional voice acting included.

Case Library

▶ Case #001 — Mina
Your cousin Mina (17) has disappeared. Her gallery holds a 1988 group photo from a closed school's photography club, and her voice memos hold a mysterious whisper: "I've been waiting so long..." Who could it be?

▶ Case #002 — Marcus
An SNS DM. "Please help. They're saying my coworker Lena killed herself. But messages keep going up on her chat after she died. Someone is using her account." Marcus is about to be framed for someone else's crime.

▶ Case #003 — Razy
A viral Reddit thread. Popular streamer Razy goes silent mid-broadcast. He plays the rest of the game without a word and then ends the stream, and nobody can reach him since. Yet his Discord auto-thank-you messages keep going out.

…and the next case is unfolding inside someone else's phone right now. The @ghostsignal_anon DMs never stop filling up.
