About NumBlocksGen

What This Site Is

NumBlocksGen is an independent educational games portal that curates and hosts browser-based math, logic, and puzzle games. Each game on this site has been personally tested and documented with detailed play notes, screenshots, and practical teaching strategies.

The site was created to fill a specific gap: parents and teachers searching for number block-style educational games often land on confusing aggregator sites or encounter broken links. This site provides a reliable, tested collection of playable games with honest descriptions of what works, what doesn't, and how to use each game effectively with learners.

Who Runs This Site

NumBlocksGen is maintained by the NumBlocksGen editor as a small catalog. This is not a commercial platform, school district resource, or corporate venture.

There are no user accounts. The site is supported through advertising (Google AdSense) and exists to help parents and teachers find working games with documented test notes.

How Games Are Selected and Presented

Games on NumBlocksGen are hosted as iframe embeds of Scratch projects or TurboWarp-packaged HTML files. Each game is credited and linked to its original Scratch project. The site uses these games under their stated Scratch licenses (typically CC BY-SA 2.0) with proper attribution. We do not claim authorization, partnership, or endorsement from the original creators.

Each game page includes test notes from actual play sessions. You'll see which controls were verified, which features worked as described, and which aspects might be confusing or slow. Screenshots are labeled as either runtime captures from our testing or creator preview images when direct capture was not obtained.

Games may be removed if they break or if ongoing testing reveals issues. The approach keeps the catalog focused on games that loaded and ran during testing.

Editorial Approach

The editorial content on game pages describes what was observed during testing and suggests ways the games might be used. Descriptions note what the game appears to practice, observed control behavior, and potential teaching applications.

Age recommendations and teaching suggestions are editorial opinions, not researched claims. For example, noting that a multiplication game drills recall rather than teaching concepts, or suggesting that saying problems aloud might help with retention.

Why "NumBlocksGen"

The site name comes from its original focus: providing a tested, playable version of a Scratch project that generates number block characters. The domain and catalog were built around that generator as the primary featured game.

Over time, the site expanded to include other high-quality math and logic games, but the original generator remains the primary featured game. The name reflects that history while making clear this is a generator-focused portal, not an official BBC or Numberblocks property.

Relationship to Numberblocks and Other Properties

NumBlocksGen is completely independent and not affiliated with the BBC's Numberblocks television series, Blue Zoo Animation, Blocks Universe, Scratch, MIT, or any of the individual game creators credited on game pages.

References to "Numberblocks" identify the BBC educational series that inspires many fan-created games. The term is used descriptively to help visitors find what they're looking for, not to suggest any endorsement, partnership, or authorization. The main featured game uses number block-style characters created by a Scratch community member, not official BBC assets.

All games are community-created Scratch projects packaged for browser play. The site uses these projects under their stated Scratch licenses (typically CC BY-SA 2.0) with attribution to the original creators. The Rights & Credits page documents the source project and applicable license for each game.
