Detectives,
Due to ongoing technical issues affecting connections to our servers, we’ve decided to suspend sales of our games in Russia. We don’t think it’s fair to sell a game in a region where we can’t maintain a reliable quality of service.
Players in Russia often have trouble connecting to our servers, and unfortunately this is beyond our control. There are government-level restrictions that affect certain types of connections to servers outside Russia, and recently the situation has been getting worse.
We’ve implemented many workarounds to reduce these issues, including better global server distribution, proxy servers, and dynamic rerouting. However, the restrictions keep changing, and it has become a constant game of whack-a-mole. Unfortunately, we also cannot legally host servers in Russia, so for now there is nothing more we can realistically do.
We’re very sorry we had to make this decision, but we believe it is the only fair one. We should not be selling a product in a region where we cannot provide a dependable experience. We hope the situation changes, or that we find a workable solution soon.
If you have any questions or comments, please feel free to contact us at [email protected] - we’ll be happy to help.
Best regards,
Eleven Puzzles Team
I bought the game earlier. Can I still play?
Of course. We are not limiting your access to our servers, although playing may still be difficult because of the technical issues mentioned above.
I bought the game, but I don’t have a partner to play with.
You can visit our Discord and look for a partner there. If you have someone specific in mind who can no longer obtain the game, reach out to us at [email protected] and we’ll try to find a solution.
When will you resume sales in Russia?
We don’t know, and we can’t give any timeline because this is beyond our control. We’ll keep looking for a technical solution that works, but we suspect that until these restrictions change, it will be difficult to resume sales while maintaining a good quality of service.

Detectives! We've got something special for you.
We listened to your feedback, read every review, and watched your videos and streams. Then we started working on an update, and it quickly grew into something much bigger.
For the past few months, we’ve been hard at work updating Parallel Experiment. We’ve fixed numerous bugs, reworked and improved many puzzles, added new features, and introduced a brand-new special level to the game!
Today, we’re releasing Parallel Experiment 2.0. The best part? It’s all available now, for free.
Near the final part of the game, you’ll now discover a completely new level filled with fresh puzzles that tie the entire experience together.
We felt the second half of the game was a bit lighter on puzzles, so we fixed that.
We admit the original ending felt rushed. It has been completely reworked. The pacing is better, the puzzles are more engaging, and the overall experience is significantly improved.
The game now features a completely redesigned hint system.
At any point, you can press the Hint button to receive a nudge in the right direction. Each puzzle includes multiple hints, most of which avoid giving direct answers - you still want to solve it yourself, don't you? Only the final hint typically reveals the full solution.
There are now over 300 hints in the game, and we hope it makes the experience more enjoyable for everyone.
We took a critical look at the game’s conversations and cutscenes and realized they were simply too long for a puzzle-focused experience.
They’ve now been rewritten and tightened to be shorter, clearer, and more to the point, while keeping the story intact.
We've squashed many bugs in the process. Big and small. Ugly and uglier.
All platforms now support Cloud Saves.
Your progress is automatically backed up online, making it easy to continue playing across multiple devices or recover your saves if needed.
Nothing.
While this update and new level is large enough for a paid DLC, we are releasing it for free. We built this to address your feedback and ensure you experience the game exactly as intended.
Both players must use the same version.
Due to major structural changes, version 2.0.0 is not compatible with version 1.0.X.
No.
If you have already completed the game or have an old save file, loading it will automatically transport you to the new content. You can start playing the new level right away.
If you enjoy this free update, please leave a review or update your existing one. It helps us immensely and allows us to keep making games. Thank you!
We hope you truly enjoy this free update. Grab your partner and jump back into the game. Have fun!
P.S. Need a player 2? Join our Discord to find a partner or report any bugs regarding the 2.0 update.

This release marks a colossal milestone for our tiny team. Parallel Experiment is by far our most ambitious project yet — and with only 7 of us, it’s been a wild ride. The scope was big, the technical challenges even bigger. But today, we’re proud. We’ve built something we believe is truly special — and we’re thrilled to finally share it with you.
Thank you for your incredible support and patience. We hope it was worth the wait. Please accept our deepest gratitude.

Detectives!
We planned to release the game on March 6th and were working day and night to meet that deadline. However, unforeseen obstacles significantly slowed our progress. In our effort to deliver the game on time and at our high standards, we had to cut some "nice-to-have" elements: extra features, optional puzzles, and even the mobile version. But we soon realized we had cut too much.
You deserve to experience Parallel Experiment as we envisioned it from the beginning. We can’t release a game missing key elements. It wouldn’t be right. So we've made the difficult decision to push the release to June 5th, 2025. This extra time will allow us to polish every aspect of the game and restore all that we cut, ensuring a perfect Parallel Experiment experience on day one.
We’re truly sorry for letting you down, but we believe it's better to launch a complete game with all the bells and whistles rather than a half-baked release. You deserve better, and we hope you understand.
Keep in mind that Parallel Experiment is a completely new challenge for us. It is five times longer than our previous game and many times more mechanically complex. It features many new elements and puzzles unlike anything you've seen before. We're navigating uncharted territory, that’s why we couldn’t predict exactly when we'd reach our destination.
One thing is certain: Parallel Experiment is shaping up to be really fun to play! Our 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.
Thank you so much for your continued support. We ask that you bear with us just a little longer. The wait will be worth it.
P.S. In a week or two we’re releasing a new trailer that’ll showcase many new areas. Keep an eye out for that!
We’re beyond excited to share that Parallel Experiment will be launching on March 6, 2025! This game is truly special, and we’re incredibly proud of what we’ve achieved. While we’re still ironing out some final details and polishing the game, we’re thrilled to announce the launch
We’re beyond excited to share that Parallel Experiment will be launching on March 6, 2025! This game is truly special, and we’re incredibly proud of what we’ve achieved. While we’re still ironing out some final details and polishing the game, we’re thrilled to announce the launch date!
Check out our new trailer showcasing a glimpse of what we’ve prepared for you:
After getting tricked by the Cryptic Killer in Unboxing the Cryptic Killer, detectives Old Dog and Ally are back on the quest to capture the criminal. A series of cryptic clues leads them across the city, taking them closer to uncovering his grand scheme: the Parallel Experiment. While the detectives are uncertain about the Cryptic Killer's exact plans, they know they must act fast to stop him. One question remains: Are they closing in on the Cryptic Killer, or walking into yet another one of his traps?
Over 10 hours of gameplay
No fillers - every moment has a purpose.
5 huge sections
Each section is bigger than our entire previous game, Unboxing the Cryptic Killer, and three times as big as Unsolved Case.
Compelling story
Told through almost 100 comic book pages and over 10,000 in-game words.
Nearly 80 puzzles
Carefully crafted to test your puzzle-solving skills.
Optional challenges
For the extra-observant detectives.
It’s because we’re pushing the boundaries of cooperative puzzle design to deliver a game that delights you with clever design, an intriguing story, unique puzzles, compelling characters, and beautiful comic-book-like graphics.
More importantly, this is a game we wish we could play ourselves. Sadly, we won’t be able to experience it for the first time, but you will. We envy you and are very proud of what we’ve accomplished!
If you haven’t already, please consider wishlisting the game. Every wishlist helps us tremendously. Thank you!
