Launch of Sokoban Online 4.0
Posted October 21st, 2026Christmas comes early for us! Due to some security vulnerabilities with Sokoban Online 3.0, we have no choice but to launch version 4.0 to the public.
There's still a lot left to do in 4.0, so this will be an open public beta release so everyone can try it and report any bugs as they come. Hopefully in a few weeks we can have a solid version 4.0 running with out any major bugs in it.
Sokoban Online 4.0 will become live very soon and accessible at SokobanOnline.com. As this version has been 8 years in the making, we hope you love it! Thank you for all your support over the years.
Sokoban Online's Future
Posted March 18th, 2026We would like to provide an update regarding the future of Sokoban Online.
Sokoban Online (currently V3) will be receiving a major upgrade with the development of V4. While we had previously considered canceling V4, positive community feedback has encouraged us to move forward with the project.
V4 is a technically ambitious undertaking, as it will be developed for both console platforms and the web. Please note that the web version will most likely not include the full campaign (Adventure Mode). Access to the campaign and several other exclusive console features will require purchasing the game on console. All existing features from V3 will remain available in the web version, which will continue to be free-to-play with full level-building capabilities.
For users with active PRO accounts, we are pleased to offer the console version at no additional cost once it is released, upon completion of a simple claims process.
At this time, we do not have a confirmed release schedule for V4, as we are actively seeking an experienced HTML5 developer to complete the project. If you know of any qualified HTML5 developers who may be interested, we would greatly appreciate your recommendations.
Sokoban Online 4.0 Delay
Posted December 26th, 2022Merry Christmas and Happy New Year from your friends at Uphill Studio! We would like to highlight the progress we have made and the short delay we are currently experiencing for the Sokoban Online 4.0 release. As you already know, version 4.0 was supposed to be released today. Unfortunaly, it will be delayed until 2023. Michel, our developer, fell ill in December and has unable to put together the finishing touches needed for a smooth release. Much work has been finished in the last few months, but not enough to confidently release to the public. We will update everyone as soon as we are about to push out the first public release of 4.0. It won’t be much longer!

New Year's Update
Posted December 28th, 2021Hello everyone! We'd like to give the community an update on the progress of Sokoban Online 4.0 before 2021 ends. While much has been done behind the scenes, there is nothing visible or playable to the community yet. Some of the progress we have done includes building over 400 puzzles for the adventure mode (still more to go!), as well as extensive coding completed for the menu system, puzzle select menus, player and builder. While we would like to give you an exact release date for 4.0, we can assure you that it will be released in 2022. We will keep the community informed when the release does take place, and will have the community involved for feedback, bug testing, and much more. One of the main focuses will be to have a flawless solution validator for modern puzzles in 4.0.
There are a few significant changes happening in 2022 that will allow us to complete 4.0 in a timely manner. Both Jeff and Michel's work schedules have opened up, allowing for a vastly improved Uphill Studio work schedule. In addition to this, we now have extensive resources to complete the task. We thank everyone for your patience and your continued support of Sokoban Online. We can't wait to use the Uphill Engine to bring you our new and exciting games!
New Website Launched
Posted September 17th, 2021It’s finally here! The release of the new Uphill Studio website is now live. Like all of the projects we are working on, there is still a lot of work left to be done. We're never satisfied until everything looks absolutely perfect, so expect to see a few minor tweaks happening to the website within the upcoming months.
