Verdict: A Case a Day

Every day you get a case file to solve. It is the same case for everyone, everywhere. When you think you have it, you write down your answer. You only get one go, so take your time. When the case closes you find out what really happened, how everyone else answered, and how you did. HOW IT WORKS You have twenty-four hours. The case closes at the same moment for every player in the world, and the app shows you when that is in your own time. You file the answer. If you get stuck you can test a hunch, up to three times a day. Each test costs you points. Nobody can see anyone else's answer until the case has closed. NO SIGN-UP, NO ADS There is no form to fill in and no password to remember. Open the app and start. You get an account automatically, because your results have to be kept somewhere. If you want them to follow you to a new phone, you can link that account to your Google account. If you would rather not, they stay on this one. You can delete everything from inside the app, whenever you like. Reminders (notifications) are optional and stay off until you turn them on. Your phone schedules them, and they never say anything about the case itself. THE SCHOOL You are a student at the Central School of Investigation, working through cases from a closed archive. Your work is marked without your name on it, and as you get better you are promoted.
