The mind-bending cooperative puzzle game, Parallel Experiment, is now available for purchase on iOS and Android. As the second installment in developer Eleven Puzzles' Cryptic Killer series, Parallel Experiment delivers even more shocking challenges and unexpected twists as you race to stop the notorious murderer from striking again.

In Parallel Experiment, the two detectives from Unboxing the Cryptic Killer now find themselves at the killer's mercy. The stakes are higher than ever, requiring seamless teamwork with a partner to solve increasingly complex puzzles that challenge both your communication skills and possibly even your friendship.

Featuring a retro, noir-inspired aesthetic and over 80 challenging puzzles, if you're seeking a cooperative experience similar to Keep Talking and Nobody Explodes, you're in luck. For just $6.99, you can dive in and test your wits against the Cryptic Killer's devious conundrums.

Oh, and did we mention that trolling your partner is a core feature? Yes, in case this all sounded a bit too serious for you, you can always disrupt proceedings by tapping windows or poking your cooperative partner to lighten the mood.

Parallel Experiment isn't just about puzzles either—you can take breaks from the main investigation with equally engaging minigames. You'll even interrogate NPCs who respond dynamically to each player's actions. Teamwork is essential here, and if you want to survive, you'll need to collaborate effectively, even if it drives you crazy.

But if you don't have a friend ready to put their problem-solving skills to the test, don't worry—you can always explore our latest list of the top five new mobile games to try this week instead! Featuring all the best new releases from the past seven days for your enjoyment on iOS and Android!
