90-150 mins

A  2-6 players cooperative online puzzle adventure, that is all about communication. Players have to follow parallel paths, explore a secret laboratory, describe what they see, and work together to unravel the mystery. Parallel Lab is played on two devices with a browser.


After escaping Cryptic Killer’s trap, the detectives thoroughly investigated the area where they had been held. Sadly they have found nothing that could move their case closer to catching the killer… Or so they thought.

Later that week, one of the engineers at the police station mentioned that the electronic equipment used to make the traps was quite old and specific. Luckily, there was only one old shop in the area that was still selling devices like that.

Armed with the new knowledge, Ally and Old Dog decided to visit the electronic shop to ask a few questions. Little did they know that that evening would have them fighting for their lives…

NOTE: This game is co-op only. It requires both players to have an active communication channel (e.g. Zoom or Discord).


In Unboxing the mind of a Cryptic Killer the detectives are separated. You’ll see different items and clues than your partner. The game will test not only your puzzle-solving skill but also how well you communicate!


Unboxing the mind of a Cryptic Killer is played in a browser, but controls like a classic point-and-click adventure.
No outside knowledge is required. You won’t have to open additional browser tabs, no Google search, don’t need to have social accounts. Just pure, self-contained fun!


No need for booking. Just get a License Key, gather your team and play!

Detectives hunting a killer - and hearing a scream before going into the building. Solve the riddles to find clues to the case...

We love collaborative puzzles and since this is the classic 2-player collaborative game, we really liked it. 

We also played their earlier game "Unboxing..." and feel that they have improved their style in so many ways. Especially the story-telling part - show don't tell - and the fact that it felt more like being in a room (though 2d) and not just looking down on a flat surface with objects to work on. 

Piecing together the clues for the puzzles required lots of communication, but the puzzles were not difficult, so progress was easily made. We were not fans of a puzzle with a periodic table and one with water temperature, but other than those we liked the puzzles. Logic, mazes, observation and translation was all kind of puzzles represented. Low frustration levels throughout. We were making dinner while playing so was a bit distracted  - we got 2 hours of play out of this. For this we thought the price was fair. 

Reviews by escape room review sites

If you liked the first game by Eleven Puzzles, then this one is sure to be a hit. We found the puzzles to be fair, and the game was fun and in places funny. The ‘forced communication’ was also done well and is guaranteed to get you talking to your teammate(s). Eleven Puzzles take their time with their games, and it shows, this is a quality experience.

If the name hasn’t quite given it away yet, this virtual room requires at least two players, on separate devices. This is because you will each be exploring a slightly different version of the same room, and communicating to solve various puzzles. As you are independent, you are free to explore without being tied to the other person’s screen which was my main bugbear of other digital games. I loved the free roam aspect, but reliance on communication as there is no way to complete the puzzles otherwise. I assume this would be the same for any number of players and is definitely a huge positive.
