Eleven Puzzles’ co-op puzzle game Parallel Experiment have made the difficult decision to push the release to June 5th, 2025. This extra time will also allow the developers to polish every aspect of the game, ensuring a perfect Parallel Experiment experience on day one.

As a plus, mobile versions (iOS & Android) will also launch on the same day, making it even easier for players to find a co-op partner and escape the clutches of the Cryptic Killer together, as crossplay is possible across all platforms! (and a Nintendo Switch version will arrive later in the year!)

Parallel Experiment is five times longer than their previous game and many times more mechanically complex. It features many new elements and puzzles unlike anything you’ve seen before. Playtesting sessions have produced rave reactions, hindered only by the unpolished state of some areas. With the extra time to smooth out the experience, you’ll be playing something truly special when June comes around!

Parallel Experiment is a 2-player cooperative puzzle game with escape room-like elements. Players take on the roles of two detectives who are often separated, each with different clues, and must work together to solve puzzles.

It’s a noir-inspired adventure with a comic book art style, featuring detectives Ally and Old Dog. While following the trail of the dangerous Cryptic Killer, they suddenly become his targets and are now unwilling participants in his twisted experiment.

It has a variety of innovative puzzles that push the boundaries of cooperative puzzle design, offering puzzles never seen before in other games.
