Playing the game
The game runs in your web browser. You’ll need a recent version of Chrome, Edge, Firefox or Safari with JavaScript turned on, and an internet connection. It’s best on a computer, works on a tablet and is readable on a phone.
Cases and casebooks
Free cases: case 1 needs no account; case 2 needs a free account.
Checkout is not currently available. The casebook payment terms below apply when purchases become available.
Casebooks: the remaining cases in a casebook unlock with a one-time payment, as set out on our Payment & refunds page. There are no subscriptions, ads or in-game currency.
“Coming soon” casebooks are announcements, not something you can buy yet. Their release dates and contents may change, and we don’t take pre-orders.
Your licence
We give you a personal, non-exclusive, non-transferable licence to play the game for your own enjoyment and learning, not for commercial use. If you’d like to use it with a class or a team, please get in touch.
Play fairly
Fenn's characters, mysteries and records are fictional. Keep your account secure. Do not disrupt the service, bypass case access or enter another player's account. Keep personal and sensitive information out of game fields. Report security concerns to 2565699@gmail.com without exploiting them.
Saves and access
Guest saves stay in your browser. Signed-in progress syncs to the cloud, with a local backup. Clearing browser data may lose unsynced saves. Features, access and availability may change. A case-access grant is not a purchase. Nothing here limits statutory rights.
