About NumBlocksGen

NumBlocksGen is an independent browser games site focused on math, puzzle, logic, and learning games that can be played without an app install. The goal is to help players find focused games with clear controls, source credits, tested screenshots, and practical guidance before they press Play.

Many games on the site began as Scratch projects and are credited on their play pages with links to the original creators. We test the hosted versions, capture distinct runtime states, record reproducible observations, disclose limitations, and explain how to approach each game. That first-hand layer is the value of the site, not just the embedded game frame.

How games are selected

We look for games with understandable rules, playable browser frames, and a clear math, learning, puzzle, or reasoning angle. A game does not need to be complex to be useful; Counting Squares uses one visible prompt, while a logic game may use a compact board that rewards planning.

Independent and source-aware

NumBlocksGen is not affiliated with Scratch, MIT, Numberblocks, Blocks Universe, or any game creator whose work is credited here. We avoid presenting credited projects as our own original games, and we avoid using official characters or logos as site branding. Each game links to its public source and non-sensitive permission record on the Rights & Credits page.

What we improve on each page

Each play page records what loaded, which controls worked, what changed after input, and what did not verify cleanly. Category pages then help visitors choose between similar games by task and input style instead of forcing them to open every card blindly.
