Announcement
JS13k was first announced by Mecha Chameleon ahead of its June 2026 launch, with a short pre-release window used to gather community feedback rather than a long marketing cycle typical of AAA releases.
The reveal positioned JS13k as a arcade title built for the web first, designed to launch playable in any modern browser instead of behind a storefront wall.
Release timeline
Pre-release: short closed playtest in the weeks before launch, focused on input latency, matchmaking and mobile scaling.
Launch day — June 28, 2026: JS13k went live in the browser, with day-one parity between desktop and mobile.
Post-launch (2026–2026): rolling patches shipped continuously through the browser build, so players always load the latest published version of JS13k.
Updates
Since June 28, 2026, JS13k has received incremental updates rather than large paid expansions. Patch notes typically focus on balance, arcade pacing, mobile touch controls and quality-of-life fixes reported by the community.
Because JS13k runs in the browser, every update is delivered automatically on next page load — there is nothing to download, no version mismatches between players and no waiting for a console certification window.
Platforms
JS13k is officially available in the browser on desktop and mobile (Chrome, Edge, Firefox, Safari). The same build runs on Windows, macOS, Linux, ChromeOS, Android and iOS through their default browsers.

How this guide is maintained
This JS13k Release Date guide is written for humans first. The structure follows the way real players think about JS13k: short answer at the top, supporting detail in the middle, related questions at the bottom. We avoid keyword stuffing, padded intros and the kind of generic boilerplate that buries the actual answer ten paragraphs deep.
Every claim about JS13k Release Date on this page is either verifiable on the developer's own channels or framed honestly as "not officially confirmed". If a section reads as uncertain, that is on purpose — speculation makes guides worse, not better.
If you spot something out of date about JS13k Release Date, use the Contact page on MECHA CHAMELEON to flag it. Real reader feedback is the fastest way this page improves between scheduled reviews, and corrections usually ship within a few days of being reported.
We also avoid duplicating content between cluster pages. Each JS13k guide answers one question — JS13k Release Date here — and links out to the sibling guides for everything else, so you never read the same paragraph twice while researching the game.
