Two detectives, two halves of a sinister puzzle, and one brilliant criminal mind orchestrating it all. Parallel Experiment, the newest release from Eleven Puzzles, is now available on Android, Steam, and iOS. This two-player cooperative puzzle adventure turns communication into your most vital tool for survival.

Two Heads Solve What One Cannot

You and a partner step into the roles of Ally and Old Dog—two investigators trapped in a psychological maze designed by the notorious Cryptic Killer, a familiar antagonist from the developer's previous works.

Each player views a distinct version of reality, with neither side revealing the complete truth. Progress hinges entirely on exchanging vital clues with your partner. Challenges range from deciphering complex codes and assembling circuitry to the unexpectedly messy task of sobering up a drunken companion.

With over 80 puzzles spanning intricate locks, mysterious symbols, and hidden documents, the game balances cerebral challenges with lighter distractions like competitive darts and match-3 minigames.

Parallel Experiment marks Eleven Puzzles' first expansion beyond a single-setting narrative. Players now navigate multiple districts of Kraków using an interactive map that tracks discoveries across locations, encountering fresh environments, buried secrets, and eccentric characters along the way.

Designed for Collaborative Chaos

The game encourages playful sabotage between partners during investigations. Disrupt your counterpart by rapping on their window, shaking their screen, or simply irritating them with persistent pokes—all in good fun.

A noir-inspired comic aesthetic frames the experience, with nearly 100 pages of digitally-rendered graphic novel sequences advancing the story. Preview the distinctive visual style in the official trailer below.



Parallel Experiment features full cross-platform compatibility. Android users can grab it for $6.99 with a 20% launch discount active for the first fortnight. Visit the official website for details.
