Halloween Case Files

Four picks from our own library. The host unlocks a paid case once for the room; other detectives join free. Prices below are per case, not per player.

The Grand Illusion

A stage magician's Halloween finale in 1947 ends with a body in the cabinet. A longer, challenging bonus investigation.

2-8 players · 90-120 min · $14.99 bonus case

Last One Screaming

A masked-killer prank at a remote lake house turns into a real murder. A slasher-flavored party headliner.

3-6 players · 40-50 min · $4.99 standard case

The Funhouse Finale

A carnival fire and a mystery under the midway lights. A spooky-season pick for fairground fans.

2-5 players · 35-45 min · $4.99 standard case

Playtime's Over

Halloween night, 1988: a toymaker is found staged in a locked toy-shop window. Untangle the death from the display.

2-8 players · 45-60 min · $4.99 standard case

Choose by the kind of spooky night you want

A short slasher-style case suits a party between dinner and a movie; a longer investigation gives a dedicated game night room to breathe. Check the player count and duration on each case file before inviting guests. Only the host needs to unlock a paid case; guests join the room without buying their own copies.

Make it a double feature

Pick one case for the main event, then keep a second in reserve if the group wants another night. Share a room link with each guest and use a video call if your detectives are in different places. Do not reveal the final solution to anyone before you play.

Common questions

Are these picks from different game publishers?

No. This is a curated selection of four Halloween-ready cases from ColdCase Party's own browser mystery library, not an independent comparison of competing games.

Does everyone need to buy a case?

No. One host unlocks the case for the room; other players join without buying it. The opening objective of Canvas of Death is free if you want to try the format first.
