Parallel Experiment’s Steam version faces delay, will now simultaneously release with the Android and iOS versions in June

by Sadie Mar 18,2025

Parallel Experiment, the cooperative puzzle game from Eleven Puzzles, has a new release date. Originally slated for a March Steam launch, the game will now debut on June 5th, simultaneously on Steam, Android, and iOS. This delay allows for the inclusion of all planned features, including optional puzzles and additional mechanics, initially considered for removal to meet the earlier deadline. The simultaneous release also means cross-play functionality will be available from day one.

Step into the shoes of detectives Ally and Old Dog as you unravel the mysteries of a twisted experiment orchestrated by the Cryptic Killer. This thrilling adventure challenges you and a partner to solve over 80 interconnected puzzles, demanding teamwork and communication. Expect a diverse range of challenges, from deciphering codes and manipulating water flows to hacking computers and even dealing with a less-than-sober accomplice. The noir-inspired setting and comic book art style create a captivating and immersive experience.

ytBut the investigation isn't all serious business! Between the intense puzzle-solving, you and your partner can enjoy retro-style mini-games, including darts, claw machines, and match-three puzzles, all with a cooperative twist. Interactive dialogues with dynamic NPCs add depth to the mystery, and for those seeking a bit of playful mischief, each level offers opportunities to playfully annoy your partner—knock on windows, shake their screen, or even doodle in your notebook!

Parallel Experiment boasts five times the content of Eleven Puzzles' previous game, promising a significantly enriched cooperative gameplay experience. Mark your calendars for June 5th and prepare to solve the case! Visit the Steam page for more details. In the meantime, check out this list of the best puzzlers available on iOS!
