You have spent an evening on Neal.fun, you have been through the password rules, the deep sea, the trolley problems and the bill-gates shopping spree, and now you want more. These are the websites like Neal.fun: small, polished, playful projects that make an idea feel like a toy.
The nearest relatives are the explorable explanations. The Evolution of Trust and Parable of the Polygons are playable essays by Nicky Case, and they feel like the same school of thought as Neal's scrolling explainers. The Pudding tells visual stories about culture with data, and Bartosz Ciechanowski's Interactive Explainers takes bicycles, lights and cameras apart in long, clear essays. For scale, The Scale of the Universe does what Size of Life does, bigger. And for the timeline lovers, Histography is a dot-filled history of everything.
The list also includes Neal's own work, so you can find the pieces you missed: Neal.fun itself, Absurd Trolley Problems, and others. One practical note: neal.fun sits behind a bot wall, which means automated checks cannot always load it, so our badge may say "alive but unverifiable". It is not broken.
Use "Surprise me from this list" to roll the dice, or start from the top: the first eight are the closest in spirit and the easiest to enjoy right away.

How we picked. Neal's projects share a few traits: a single clear idea, an interface you can use in seconds, and a sense of humor about the subject. We looked for sites with the same traits, whether they come from independent creators, universities or Google. We did not include anything that looks similar but is mostly ads.
Three routes from Neal.fun.
Why Neal.fun matters. It shows what you can do when a developer treats every page like a small short film. Our job is to find the rest of that family, so we welcome submissions when you find one.
More lists. Fun Websites to Play With is more game-centric, Fun Educational Websites is more learning-centric, and the Interactive Websites list is more technical. If you want something unplanned, take me somewhere odd.
Nicky Case's explorable explanations, The Pudding, Bartosz Ciechanowski's explainers, The Scale of the Universe and Histography are the closest in spirit. They share a clear central idea, an easy interface and a playful tone. All are on this list and checked daily.
Neal.fun is the creation of Neal Agarwal, who built many of the projects on it, including The Password Game, Infinite Craft and The Deep Sea. The site collects his games, visualizations and other interactives in one place, with each project opening as its own self-contained page.
Explorable Explanations is a curated hub for interactive essays you can play with, and Experiments with Google collects creative-coding and AI toys. Our own directory also gathers them, with filters for mood, time and mobile support so you can find similar sites quickly.
neal.fun uses bot protection that blocks automated checkers, so we cannot always confirm it loads. We treat bot walls as alive but unverifiable instead of broken, and re-check it with a browser-based test each week. If you see this badge, the site is almost certainly fine, just unable to be verified by a robot.
