Known limits
- The builder needs WebGL. A browser or device that blocks WebGL shows the on-page fallback instead of the 3D scene.
- Large numbers are supported up to 1,000,000, but complex scenes use more graphics memory and may be slower on lower-powered devices.
- Saved characters are not synced between devices or browser profiles.

How It Works
How the 3D Numberblocks Generator works
The game turns one typed number into a playable 3D Numberblocks character. Start with the block count, then use the builder controls to adjust layout, style, scene, and math actions without leaving the page.
What you can make
This custom Numberblocks maker is for building your own Numberblock character instead of only playing a fixed generator. Each character starts from a number, so a small value becomes a simple stack while a large value becomes a bigger 3D block model.
Use it when you want a specific number, a classroom-style visual, a transparent Numberblock image for a worksheet, or a playful character design with your own colors and face.
Main game functions
The Create panel controls the number and layout. The Customize panel changes color, material, face, expression, headwear, add-ons, and background. The Play tools let you jump, dance, celebrate, fall apart, rebuild, split, merge, and combine characters.
Photo Mode is built for quick sharing. You can frame the 3D scene, choose a transparent background when needed, and download a PNG without uploading the character to an account.
- Number input range: 0 to 1,000,000.
- Layouts include compact, tall, wide, rectangle, steps, pyramid, solid, and random.
- Saved Characters stay in local browser storage on the same device.
