The changes that shaped the site

  1. Physics playground

    Physics Toys make the 3D Builder more playful

    The 3D Builder now has a dedicated Physics tab for experimenting with the Numberblocks already in your scene. Place an Explode, Magnet, Black Hole, Tornado, Vortex, or Shockwave field on the playground; tap a block to Freeze or Float it; or use Zero Gravity, Launch, Stop Motion, Resume Motion, and Reset Physics. Explode now offers POP, BOOM, and MEGA BOOM, each with clear visual and sound feedback. Black Holes can draw in blocks and send them back with RELEASE!, while the camera remains available for zooming and panning during play. Larger builds are naturally harder to move, and the playground keeps blocks inside its boundaries. Physics play never changes a block’s number, style, or saved build. By default, a block keeps its natural resting pose; turn on Auto Stand if you would like settled blocks to return upright when there is space.

  2. First-time experience

    A quick guided tour for new sandbox builders

    First-time visitors to the 3D Builder now get a short, hands-on tour that teaches the basics by doing them. It walks through adding a Numberblock, selecting and moving it, then rotating, panning, and zooming the scene — with instructions that match the device being used, whether that is a mouse, a trackpad, or a touchscreen. The tour appears only for visitors who have never used the sandbox before, so long-time builders are never interrupted, and anyone can replay it later from the Help menu. It is available in English, Spanish, French, and Portuguese.

  3. Builder experience

    Richer character styling and smarter large-number framing

    Today's 3D Builder update brings a broader set of facial-expression and accessory choices, with their positions retained when a character is saved. It also makes large builds easier to inspect: camera fitting now works from the character's real projected bounds, so even a 100,000 block frames naturally instead of feeling cropped or too distant. The 3D landing page now uses lighter review imagery for faster loading, and the site's privacy-disclosed usage measurement is enabled by default.

  4. Settings & reliability

    More control over music, materials, and reliable building

    Yesterday's 3D Builder update adds a background-music volume slider, from 0–100%, that takes effect immediately and stays with your saved settings. Character placement now stops with a clear message if there is no safe open space, rather than stacking a build on top of another. Materials, far-away large-number lighting, and the Star Headband have been refined, while PNG export, sound recovery, keyboard dialog handling, and saved-setting validation received reliability fixes behind the scenes.

  5. Reliability

    Creation gallery with stronger image loading

    Added six real builder creations that reopen their matching number and layout. Every card takes visitors into the builder with the same starting number and arrangement, so they can inspect an example and keep building from it. If image delivery has a short cache failure, the gallery now automatically tries a fresh request up to twice instead of leaving a broken thumbnail.

  6. Start experience

    Direct launch from the preview

    Opening the 3D Builder or its preview now starts the tool directly, without requiring a second play confirmation. The preview action creates Numberblock 1 and moves visitors to the game area, making the first build feel like one clear step instead of a two-stage hand-off.

  7. Quick start & mobile

    Shareable presets and a better mobile workspace

    Added one-tap 10, 12 Rectangle, and 25 Square starts with shareable links, so a parent, teacher, or friend can open the same starting idea. On phones, controls snap into a bottom panel that leaves more of the scene visible; landscape uses a scene-and-sidebar layout for easier adjustment.

  8. Builder range

    Build whole numbers up to 1,000,000

    Expanded the original builder from smaller values to whole numbers up to one million. Larger values use layouts adapted to their scale, while local saves and spoken-number feedback continue to work with the number being built.

  9. Play mode

    Multiplication mode joins the 3D Builder

    Added ×2 and ×10 controls alongside the existing number steps, so visitors can turn a current whole number into a new multiple in one action. The builder immediately creates the new character, making it easier to explore multiplication patterns without retyping each value.

  10. Sound

    More reliable spoken-number audio

    Moved number speech to a maintained service run for this site, improving the voice path used by the original builder. This keeps the spoken-number feature aligned with the builder as it grows, rather than depending on an older external setup.

  11. Major release

    Original 3D Builder launched

    Released the original Numberblocks character builder made for this site, rather than another embedded community project. It runs in the browser and lets visitors build a number, choose its layout, colour, face, material, and scene, then combine or split characters, save work on the device, and export a PNG image.

  12. Site milestone

    The site becomes multilingual

    Added English, Brazilian Portuguese, Spanish, and French routes alongside language controls. Visitors can choose a language from the site menu and keep that language while moving between the builder, version pages, guides, and site information.

  13. Site launch

    Numberblocks Generator launches

    The first browser hub went live with playable generator paths, version comparisons, and a focus on quick, no-install access. It gave parents, teachers, and casual players one place to start a suitable version in the browser instead of searching through separate project pages.
