Build First, Switch Versions Anytime
Start in the main generator, then switch to Classic NBB, Websim, Scratch, or 1 to Infinity when you want another way to play.
Play in the Main Generator first, then open Classic NBB, Websim, 1 to Infinity, or Scratch from the same page without keeping five tabs open.
Main Numberblocks Generator
Build custom Numberblocks
Start here to build custom Numberblocks in the main generator. It runs on this site, loads in the browser, and is the best first stop for a new visit.
Classic NBB Numberblocks Generator
Play the classic fan-made version
Use Classic NBB when you want the classic fan-made TurboWarp version. It is a good switch when you want the original NBB-style player instead of the main generator.
Numberblocks Playground Websim
Try the sandbox playground
Open Websim to drag blocks, merge numbers, spawn villains, and chase achievements in a sandbox playground.
Numberblocks Generator 1 to Infinity
Explore bigger numbers
Use this version when the normal generator feels too small and you want larger values or bigger number patterns.
Numberblocks Generator Scratch
Open a Scratch-style project
Use Scratch when you want the Scratch project path. Play in the faster browser player first, then open Scratch for notes or remix details.
