About Caso Probado
Someone is lying to you. Your job is to prove it.
In Proven Case, you don't read the solution: you figure it out yourself. Each case has a file and seven people: four suspects who are lying to you and three witnesses who aren't. You write them whatever you want, just like you would to anyone. They reply. And not everyone tells the truth.
TWO WAYS TO INVESTIGATE
• Short Challenges. Every morning at 8:00, a challenge with five tasks: catch the liar, reconstruct what happened, verify an alibi, recall a scene, and discover who did it. The same challenge for everyone, with your streak and your result to share.
• The Academy. Levels that never end: five tasks per level; complete four and move on to the next.
• Complete Cases. A whole file and seven people to interrogate. Each case is investigated in five missions, until you accuse the culprit with evidence.
HOW TO INVESTIGATE A CASE
• Interrogate each person. Ask them where they were, what they saw, what they knew about the deceased.
• Present the facts to them. Open the file, underline the line that contradicts what they've told you, and show it to them.
• Until they confess. When someone has no other option, they talk. What they admit is automatically noted in your notebook.
• Accuse with evidence. Choose the culprit and mark three things in the notebook that prove it.
• With full access, you can also work independently: question whomever you want and accuse whenever you want.
START WITH A PRACTICE CASE
Commissioner Ferro guides you through "The Last Performance": an illusionist dies live on stage in a theater on Gran Vía. Ten minutes to learn how to spot a lie.
SOME CASES
• The Last Service (difficult). A chef dead in his own kitchen, four people who lied to him, and a bottle missing from the inventory.
• Everything was signed (sort of). A painting returns from an exhibition, and the lab discovers a copy. Each transfer has its signature. No signature guarantees what was inside the frame.
• Twenty-one seconds (easy). Twenty-one seconds of audio on the front page of a Sunday newspaper. The woman who said them has been in a coma since that very morning. And a fifty-one-minute recording that no one wants to release.
A new case every Thursday.
SOLO OR WITH FRIENDS
• Play solo or with up to six others on the same case: interrogate together, share notes, and vote on who to accuse.
• Create your agent badge, add friends using their username, and compare who solves cases best on the leaderboard.
WHAT MAKES IT DIFFERENT
• The suspects don't follow a script. They remember what you've asked them, contradict themselves, get nervous, and shut down if you corner them.
• No one confesses just because. A question doesn't force anything; a piece of information they can't explain does.
• Each case is played at your own pace. Leave it unfinished and it will be waiting for you right where you left off.
• No ads.
