Questions
Before you start.
Is the daily case really free?
Yes, and it always has been. No account, no app, no trial that ends. A new case appears every day and you can play it in the browser you are reading this in.
Do I need the book to play?
No. The daily case stands on its own. The books are for people who finish the free one and want a hundred more without waiting a day between each.
Are the books the same puzzles as the site?
No. The site gives you one case a day from its own rotation. Each book is a hundred fresh cases, printed, with the answers sealed at the back.
How hard is it?
Most people close a case in four to eight minutes. Finding the words is the easy half. Working out which suspect the grid is pointing at is where it earns the word mystery.
When does the next case arrive?
At midnight, by your own clock. The page counts down to it once you have closed the current one.
Can I play the cases I missed?
Yes. Past cases stay in the archive on the case page. Signing in with an email opens them, and keeps your streak across devices.
