About Unlock!: Mystery Adventures, from BoardGameGeek:

Unlock! is a cooperative card game inspired by escape rooms that uses a simple system which allows you to search scenes, combine objects, and solve riddles. Play Unlock! to embark on great adventures, while seated at a table using only cards and a companion app that can provide clues, check codes, monitor time remaining, etc. Unlock! Mystery Adventures features three "escape room" scenarios that you can play on your tabletop: The House on the Hill (easy): What's going on in this run-down manor? Explore the sinister pieces and foil the curse that haunts this desolate place. Designed by Fabrice Mazza, illustrated by Pierre Santamaria. The Nautilus' Traps (medium): Attacked by a sea monster during a dive, you seek shelter by opening a hatch in an old submarine. Find a way back to the surface! Designed by Arnaud Ladagnous, illustrated by Florian de Gesincourt. The Tonipal's Treasure (difficult): Captain Smith hid his treasure on Tonipal Island. Unravel the mystery before Johnson, another treasure hunter, beats you to it! Designed by Billy Stevenson & Sebastien Pauchon, illustrated by Sergo.
