Two detectives. Two perspectives. One chilling mystery. Parallel Experiment, the latest mind-bending release from Eleven Puzzles, is now live on Android, Steam, and iOS. This innovative two-player cooperative puzzle adventure turns communication into your most powerful tool—and your only way forward.
Two Is Better Than One
Step into the shoes of Ally and Old Dog, two detectives caught in a twisted psychological experiment orchestrated by the infamous Cryptic Killer—a name familiar to fans of the developer’s previous titles. Trapped and isolated, each player experiences a unique half of the same world. No single player has the complete picture. Success hinges entirely on sharing clues, interpreting details, and trusting your partner’s observations.
From decoding encrypted messages and repairing circuit boards to reviving a groggy ally, the challenges are as varied as they are immersive. With over 80 puzzles to solve, you’ll encounter complex locks, mysterious symbols, hidden notes, and unexpected mini-games—including darts and match-3 rounds—that break the tension between intense investigative sequences.
Unlike earlier entries in the Eleven Puzzles series, Parallel Experiment expands beyond a single setting. Explore multiple districts of Kraków using an interactive map that tracks your progress across locations. Uncover new environments, discover hidden secrets, and interact with a cast of eccentric locals who may hold vital clues.
It’s a Parallel Experiment
Need a little mischief during the investigation? The game lets you interact with your partner in playful—and frustrating—ways. Tap on their window, shake their screen, or give them a well-timed poke just to throw them off. It’s all part of the experience.
Styled in a striking noir comic book aesthetic, the game’s narrative unfolds through cinematic cutscenes spanning nearly 100 pages of illustrated storytelling. The atmosphere is dark, tense, and dripping with mystery—perfectly matched to the psychological depth of the plot.
