'Parallel Experiment' Noir Co-Op Puzzle Game Launched by Eleven Puzzles

By FinnJul 23,2025

Two detectives, one chilling mystery, and a mastermind pulling the strings. Parallel Experiment, the newest title from Eleven Puzzles, is out now on Android, Steam, and iOS. This cooperative two-player puzzle adventure thrives on teamwork and communication.

Stronger Together

You and a teammate control Ally and Old Dog, detectives ensnared in a sinister psychological test orchestrated by the Cryptic Killer, a familiar figure from the developer’s earlier games.

Each player experiences a unique perspective, with progress hinging on sharing clues. You might crack a code, repair electronics, or even rouse a drunken character.

With over 80 puzzles, the game features complex locks, cryptic symbols, and scattered clues. Between mysteries, enjoy darts or match-3 challenges.

Parallel Experiment breaks new ground for Eleven Puzzles, moving beyond a single setting. Explore Kraków’s diverse areas with a map to track your journey, uncovering fresh environments, hidden secrets, and quirky locals.

A Shared Challenge

Feeling playful? Tease your partner mid-puzzle by tapping their window, shaking their screen, or giving them a playful nudge.

Rendered in a striking noir comic book style, the game includes nearly 100 pages of cutscenes. Watch the trailer below for a glimpse!

Parallel Experiment offers crossplay across all platforms. On Android, it costs $6.99, with a 20% discount for the first two weeks. Visit the official website for more details.
