The Hidden Side: Mysteries
True cases, played together
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The Hidden Side is 60 investigations drawn from true stories. One sentence, one absurd situation, and a single question: what actually happened?
THREE WAYS TO PLAY
On your own, at your pace: flip the card when you think you have it.
Remotely, two of you: open a room and send the invite code to a friend. One of you is the Keeper and knows the answer, the other asks the questions. You don't need to be online at the same time — questions wait for you, and a notification tells you when it's your turn.
In the same room: one phone is enough. One player referees, the others investigate, and handing over the device is protected by a press-and-hold.
CLOSED QUESTIONS, THREE ANSWERS
Yes. No. Doesn't matter. That is the whole mechanic, and it holds a whole evening.
ONE FREE INVESTIGATION EVERY DAY
Unlock one free investigation a day — the one you choose — on top of the Premium content.
A TUTORIAL YOU ACTUALLY PLAY
No rules to read: on first launch you run a real demo investigation, place your bet on the answer, then flip the card.
EIGHT LANGUAGES
English, French, Spanish, German, Italian, Dutch, Polish and Portuguese.
Every game ends properly: case closed or complete failure, with your score and a challenge to send straight back.

Version 2.0.0 — The Hidden Side is now a game you play together.
PLAY REMOTELY
Open a room, send the invite code to a friend: you each investigate from your own phone. One of you is the Keeper and knows the answer, the other asks the questions. You don't need to be online at the same time — questions wait for you, and a notification lets you know when it's your turn. Clues confirmed by the Keeper are revealed to the Investigator as the game goes on.
KEEPER MODE
The board game, guided by the app, on a single phone. One player referees, the others investigate. Handing over the device is protected by a press-and-hold, and the checklist of clues to guess fills up as you play. Two possible endings: case closed, or complete failure.
