doodlecube.io was one of the predecessors of Bloxd.io. The website featured only the Doodle Cube game mode. Doodle Cube was later added to the Bloxd.io website, and since then the website was defunct.
However, the doodlecube.io website has been repurposed as an “unblocked domain” of Bloxd.io since 15 December 2025, where it is identical to Bloxd.io.
