Numberblocks Playground Websim

Numberblocks Playground Websim is the browser playground version for users who want a 3D sandbox instead of TurboWarp-style 2D play. It includes TV10TheCool's expanded fork of Numberblocks Playground on Websim, with hundreds categories, villains, achievements, and recording tools.

Choose Numberblocks Playground Websim when you want sandbox play: drag blocks, merge values, spawn Terrible Numbers, and look for secrets. It is different from typing a number into a classic generator stage.

This page keeps the player focused on Numberblocks Playground Websim only. For quick 2D generator sessions, use the main NBB version or 1 to Infinity from the related pages below.

Start the player above, then use these in-game controls on the grassy stage.

Move: Drag any block with your finger or mouse to reposition it on the playground.

Lift: While dragging, use the scroll wheel or pinch gesture to change a block's height above the ground.

Join: Bump two positive numbers together and watch the blocks merge into a new total.

Talk: Place two blocks near each other and wait. Numberblocks love to chat when they are close enough.

Reset: Tap the broom icon in the bottom bar to clear the playground and start fresh.

Use the Numbers tab at the bottom to spawn 0 to 100 in Numberblocks Playground Websim, then switch tabs for negatives, fractions, operations, and more.

Operations: Open the Operations tab to spawn math symbols (-, +, x, /) as blocks you can place on the stage.

Sequences: Tap a number, then an operator, then another number to perform a calculation in order.

Modifiers: The Modifiers tab affects every block on the playground at once, which helps with classroom demos or wild experiments.

Compound Numbers and Multi-Spawn tabs offer extra ways to build larger values or spawn groups quickly.

Irrationals and Fractions tabs include special values such as π and common fractional Numberblocks.

1 to 10: The original squad from the show. Each number has its own personality and look.

Square Club: 4, 9, 16, 25, 36, 49, 64, 81, and 100 are proud squares. (4 is still scared of circles.)

Rectangle Club: 12, 18, 24, 28, 32, 42, 48, 54, 56, 63, 64, and 72 love rearranging themselves into different rectangle shapes.

Step Squads: 3, 6, 10, and 15 form perfect staircases when you line them up.

Special guests include 11 the Soccer Star, 14 the Skateboarder, 20 the Tap Dancer, and 26 the Secret Agent.

Browse the Hundreds through Nine Hundreds tabs to spawn 100 to 999, plus Alternatives and Maps for extra worlds in Numberblocks Playground Websim.

Terrible Twos: Small orange troublemakers you can spawn from the Terrible Numbers tab.

Terrible Four: A green 2x2 menace that plays by villain rules instead of hero merge logic.

Octonaughty: A giant 8-block villain and Octoblock's arch-nemesis.

Tip: Villains cannot merge with heroes. They only merge with each other, so keep hero and villain play separate for the intended behavior.

Nine's Sneeze: Nine is shy and sometimes sneezes his center block out, splitting into an 8 and a 1.

Infinity: Spawn the heaviest block and drop it from high up to trigger a massive earthquake effect.

Negative Land: Spawn more than ten negative blocks and the world inverts. Positives are vaporized in this mode.

Crossovers: Reach a total playground value of 85 to unlock Windows. Mario is always ready for a "Let's-a go!"

Most of these secrets begin in the Negative Numbers, Crossovers, and Maps tabs. Try them after you learn the basic controls.

The playground hides 16 achievements. Open the trophy icon in the bottom bar to track what you have unlocked.

Hints from the in-game guide: try irrational numbers, unlucky number combinations, and different graphics quality modes.

Use Settings to switch between Optimized, Standard, and High Graphics. Some secrets respond to visual or performance modes.

Record and Photo buttons let you capture clips or screenshots when something surprising happens on the stage.

Two Hundreds (200 to 299): Numbers follow the same body rules as Hundreds. 200's body combines with tens and ones.

Numbers 201 to 299 spawn near the ground, about 1 unit above the surface. 200 itself spawns higher, around 20 units up.

Three Hundreds through Nine Hundreds extend the same pattern for 300 to 999.

Root blocks come from Operations. Root block numberlings use √ and appear in yellow.

Original project credit goes to @Simulation on Websim. This Numberblocks Playground Websim page features TV10TheCool's expanded Numberblocks Playground fork.

Use the in-page player above to load Numberblocks Playground Websim, dismiss the welcome tour if you prefer, then pick a tab and spawn your first number.

Open the fullscreen player or Source link when the frame feels tight, when number buttons fail to appear, or when you want the full browser window.

If the bottom number bar stays empty, check that api.websim.com is not blocked by an ad blocker or network filter. The spawn buttons depend on the Websim platform script.

For quick Scratch-style play without a 3D sandbox, switch to the main generator or 1 to Infinity from the related pages below.

Numberblocks Playground Websim depends on the Websim platform and browser frame permissions. Refresh once, then open the site player in a new tab if the frame stays blank.

Mobile browsers can be stricter with in-page embeds. Landscape mode, fullscreen, or the new-tab player gives the sandbox more room.

Allow api.websim.com when spawn buttons are missing. That script powers the number bar in the Websim player.
