Party kits, phone mysteries, boxed case files and puzzle apps: what each kind of mystery game is best for, so you can pick the right one for tonight.
There's no single best mystery game. It depends on who's playing, how many of you there are and how long you've got. Here's what each kind of game is good for, so you can pick the right one for your night. We make phone mysteries ourselves, and we've said plainly where ours fit.

A phone mystery is a story-led case you play on your phone: a voice to follow, clues on the screen and puzzles to crack, start to finish in one night.
This is where our games sit. They play in your phone's web browser with no app, and Stay on the Line (15+) is free from start to finish. See everything on our Play at home shelf.

A murder mystery party kit gives every guest a character, a costume idea and a booklet of secrets, and the evening plays out over dinner.
The free option: Murder in the Dark needs nothing but a dark room, and our free role dealer deals the parts on one phone.

Escape and mystery puzzle games for a phone or tablet, played alone at your own pace.
In Stay on the Line a hint costs you time, never money, and there are no ads. Today's puzzle is a free one every day.

A box of evidence to work through: letters, photos, reports and maps. Some come as one box, others as a monthly subscription.

A boxed escape or mystery game is easy to wrap and turns into a night in for the person who opens it.
