Parallel Lab is a two-player cooperative online puzzle adventure that is all about communication.

Follow parallel paths, explore a secret laboratory, describe what you see, and work together to unravel the mystery!

In Parallel Lab, 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.

What reviewers are saying about the game?

I thoroughly enjoyed this game. I went in with fairly low expectations but was absolutely blown away. The interactivity and independence are a real positive, and the puzzles themselves were just as good as any physical room.

"Parallel Lab" has an excellent theme and style that draws on classic retro style animation and encourages a level of collaboration while still giving each player something to do, which can be hard to navigate in the online realm of puzzling. Eleven Puzzles does it quite seamlessly!

The puzzles are very well done and have the perfect level of difficulty - the answers are not super obvious, you are guided only by your logic. Overall, I liked the game and I rate it 5/6 because it was fun.

Parallel Lab is an interesting game, with an innovative concept and technology that works surprisingly well. It’s very rare for a game to appear that does something really different and Parallel Lab succeeds.

Game story


The detectives are following Cryptic Killer's trail

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...

Frequently asked questions

Should I first play Unboxing the mind of a Cryptic Killer?

No need. Parallel Lab is the second game in the series, but we designed it to be played comfortably as a standalone game.

How other players join the game?

You just use the same License Key. Pay once for the whole team!

Can we play on mobile devices, e.g., smartphones?

The game is designed for PCs, laptops, or tablets. The bigger your screen, the better, so we don't recommend playing on smartphones, although if you want a challenge, then that's on you!

What to do when we are stuck on one of the puzzles?

Each of the puzzles has detailed hints from the first, which will generally point to the items that should be used to complete the puzzle, to the last, in which the solution is given. Hints in between these should provide pointers to help you solve the puzzle yourself. The hints can be found using the light bulb icon on each item's screen.
