5 JUNE 2025 - Eleven Puzzles is proud to announce the launch of Parallel Experiment, a brand-new cooperative escape room-style puzzler available now on Steam, iOS, and Android!

Two detectives, one deadly experiment, a race against time. ​
​Each player only has one half of the puzzle.

Parallel Experiment costs $9.99 on PC, $6.99 on iOS & Android. (regional pricing may vary). The co-op puzzler has a two-week 20% launch discount and players can get an even better deal with the Cryptic Killer Bundle, including Unsolved Case, Unboxing the Cryptic Killer, and Parallel Experiment, which offers an additional discount.

Just like in their previous titles, crossplay is possible across all platforms! ​
​(+ a Nintendo Switch version will arrive later in the year!)
