Parallel Experiment, the cooperative puzzle game from Eleven Puzzles, has a new release date. Initially slated for a March Steam launch, the game will now debut on June 5th, simultaneously on Steam, Android, and iOS. This delay allowed the developers to retain all planned features, including optional puzzles, additional mechanics, and the mobile version, ensuring a complete and consistent experience across all platforms. Cross-play functionality will be available at launch.

Step into the shoes of detectives Ally and Old Dog as you unravel the mysteries of a twisted experiment orchestrated by the Cryptic Killer. Solve over 80 interconnected puzzles, requiring teamwork and communication to progress. Expect a blend of cipher deciphering, water flow redirection, computer hacking, and even the unexpected task of waking up a drunk detective! The game's noir-inspired setting and comic book art style create a captivating atmosphere, adding to the tension of your race against time.

Beyond the core puzzle-solving, enjoy cooperative retro-style mini-games like darts, claw machines, and match-three challenges, adding a lighter touch between intense investigations. Interactive dialogues with dynamic NPC responses deepen the narrative, and mischievous players can even annoy their partners with in-game pranks like window knocking, screen shaking, or questionable notebook doodles.

Featuring five times the content of Eleven Puzzles' previous game, Parallel Experiment promises a significantly richer cooperative experience. The game launches June 5th. Visit the Steam page for more details. In the meantime, check out our list of the best puzzlers currently available on iOS!
