Many developers host versions of popular games on GitLab/GitHub Pages because: Domain Reputation
Origins and Motivation Unblocked game collections have long been popular among students and casual gamers who encounter network restrictions that block popular gaming portals like Poki, CrazyGames, or Newgrounds. When direct access to these portals is blocked, enthusiasts sometimes mirror or rehost small HTML5 games or create wrappers that serve game files from alternative hosts. GitLab and other code-hosting platforms are attractive for this purpose because they provide free hosting for static pages, easy version control, and simple collaboration tools. For many contributors the intent is pragmatic: restore access to lightweight, browser-based entertainment during free periods or to preserve small games that might otherwise become unavailable. pokiunblockedgitlab link
