Blockrain is a self-hosted falling-block puzzle game. This local version uses the MIT-licensed Blockrain.js project with a cleaned local entry page and no third-party ad scripts.
Play Blockrain free online at Vivid Coder GamesVerse — no download, no signup, and no ads of our own. It runs instantly in your browser on desktop, Chromebook, and mobile, and is unblocked and safe to play at school or work.
Some browser games keep running once the page is loaded; Blockrain is mostly playable as long as the tab stays open, even if your connection drops briefly.
Most players reach the later stages of Blockrain in 30–60 minutes, but the harder puzzles can keep replay sessions going for weeks.
Blockrain is solo by design, so there's no online pressure. You set your own pace and goals.
No account is needed for Blockrain. Just open the page and play; your session stays local to the browser.
