Official announcements, newest first. Posted on Steam.
- Community AnnouncementsSecurity Patch, QoL, Discord and MoreGood Morning!Apparently there is a bit of a security risk going on with older Unity builds, so I updated to the newest engine version and rebuilt the game. Hopefully nothing is broken, but I tested most of it and it seems fine. Of course, if you notice anything let me know in the Discussions. More info about the Unity security thing here. I used this opportunity to also add some minor quality o...
- Community AnnouncementsName change coming soonNew name? Why? Yes, after thinking about it for a while, I've decided that this game needs a name change. The reason is pretty simple: B.i.t.Lock is just not a good name... It sounded cool on paper and has grown on me a lot, but I realized that it has some major flaws. It isn't search-friendly, can be tedious to type because of the dots in the name and sometimes even confuses people. With this...
- Community AnnouncementsB.i.t.Lock 1.4: Challange Packs Update{STEAM_CLAN_IMAGE}/35600166/1c1430be293b3d7c76819e4bebba5ac9544c7a64.png B.i.t.Lock 1.4 is now live! The new Challenge Packs Update for B.i.t.Lock is finally released. There is lots of stuff to do and more! What's new? 150 new levels were added to the game as 50 challenge packs. That raises the total amount of levels from 76 to 226! That's a lot! And it certainly took me a while to make them al...
- Community AnnouncementsWeekly Challenges are DONEWeekly Challenges?... Yes, if you didn't know already, I was making a few levels a week and uploaded them on Itch every week (now that I think about it, I feel kinda stupid that I didn't make them available on Steam as well, but I guess I was just too lazy to implement all that network and database stuff). Now, after making 50 Challenges with 150 new levels, I can finally rest. Wait! What if I...
- Community AnnouncementsB.i.t.Lock FREE Challenge Packs UpdateAs you may or may not know, I've been doing my Weekly Challenges now for almost a year and posted them regularly on Twitter ( ). However, they were only playable in a web browser and I never got to implement them in the main game. I've decided that I will be stopping after my 50th Weekly Challenge and update the game with all of my levels that I created over the year. This update will be COMPLE...
- Community AnnouncementsWorkshop UpdateAfter a year in development, the update is finally finished. Level Editor and Steam Workshop When pressing 'Start' in the Main Menu, you will now see a 'Workshop' button in the bottom left, which will lead you to the B.i.t.Lock Workshop.

Why Block in the Lock mods break
A mod is compiled against one version of a game. When the game updates, anything that reached into the parts that moved stops working, and it usually stops working silently rather than with a message that explains itself.
That is what the table above counts. It is not a guess: each row is a mod the community has reported as broken by that specific release. The number is a fair measure of how disruptive an update was, and it is the reason people delay updating a game they have modded heavily.
Common questions
Does IndexGG host Block in the Lock mods?
No, and it never will. Every download link points at the author's own page on Nexus, GitHub, CurseForge or wherever they published it. We index the ecosystem; the files stay with the people who made them.
Where does the compatibility data come from?
From the communities that maintain it in the open, not from guesswork. Each claim carries how it is known, so a reported breakage is never presented as though the author said it.
Why is a mod listed as broken when it works for me?
Compatibility depends on your exact game version and the rest of your load order. A mod marked as broken in one release may work fine on an older one, which is exactly why the version is recorded next to the claim rather than a bare yes or no.
