Parallel Experiment is a mind-bending co-op puzzle thriller arriving on mobile later this year

Author:Kristen Update:Mar 19,2025

Parallel Experiment, a co-op crime thriller puzzler from Eleven Puzzles, is set to launch on Steam this March. A mobile demo is also planned for iOS and Android later in the year, with a full mobile release to follow.

This exciting game casts you as detectives Ally and Old Dog, working together to solve the mystery of a ruthless killer. Similar in style to Keep Talking and Nobody Explodes, Parallel Experiment features split-screen gameplay where players, often in separate locations, must communicate clues and collaborate to solve over 80 unique puzzles.

The game includes an in-game notebook for tracking clues, cooperative dialogue, a stylish noir comic book aesthetic, and even playful features like knocking on windows or poking your partner for added fun. Cross-platform play is also confirmed, offering a unique cooperative experience regardless of whether players are together in the same room or using separate devices.

While the co-op puzzle genre isn't new, Parallel Experiment benefits from the extensive testing and refinement seen in similar titles, promising a polished and engaging mobile experience.
