Physics Toys

Play with Physics

Bring your creations into Numberblocks Playground and experiment with Rocket, Magnet, Black Hole, Tornado, Vortex, Shockwave, Float, Zero Gravity, and more in one saved scene.

Rocket

Fit a Rocket, then launch a Numberblock from the Physics panel and guide its flight in the playground.

Black Hole

Place a Black Hole in the scene, watch nearby Numberblocks curve inward, then release them when you are ready.

Tornado

Create a spinning Tornado that lifts Numberblocks from the ground before sending them back into the scene.

Zero Gravity

Switch on Zero Gravity to let the whole scene float, then return to ordinary physics whenever you want.

How It Works

How to Play

Numberblocks Playground uses its built-in Numberblocks Generator to turn 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

The built-in Numberblocks Generator lets you build your own Numberblock character, then place it in Numberblocks Playground rather than using a fixed model. 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

In Numberblocks Generator, use the Create panel to set 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.
