Hi — I'm the person who built the Madderverse, and this page is the “why” behind it.
The problem
I got tired of watching kids' games on the App Store and Play Store turn into ad-delivery machines. You hand a phone to a kid for a quick break, and within five minutes they've sat through more video ads than they've actually played. Some games are barely playable without spending money. That isn't a kids' game — that's a marketing pipeline aimed at children, and most parents notice it the moment they look up from their own screen.
I made the Madderverse because I think kids deserve better than that.
The promise
Every game on this site is, and will always be:
- Free. No purchases, no subscriptions, no premium tiers, no “watch a video to continue.”
- Ad-free. No banners, no interstitials, no sponsored content slipped into the gameplay.
- Tracker-light. Anonymous visit counts only. No personal data, no profiles, no third-party advertising trackers. (See Privacy & Legal for the full picture.)
- Browser-native. Nothing to install. Nothing to sign up for. Open the link, and it plays.
Why I'm doing this
I grew up with very little. The games and creative tools other kids took for granted — drawing programs, music makers, a computer in the bedroom — most of that was out of reach for me. As a parent, I've watched my own children miss out on things I couldn't afford to give them, and that hurt in a way I didn't have words for.
For the first time in my life, I have access to powerful tools I never imagined I would. Generative AI is one of them. Used carelessly, it produces noise. Used with care, in the right hands, it lets one person ship things that used to take a studio and a budget.
I believe AI belongs in the hands of people who grew up the way I did, and people who didn't — and especially in the hands of kids who want to learn to draw, to code, to compose, to build worlds. The Madderverse is what that belief looks like when I act on it: a small, growing collection of games made with care, paid for by me, given away freely.
What I hope you take from this
If you're a parent: I hope your kid gets a few honest minutes of fun here without a single ad, and you get a few quiet minutes back.
If you're a kid: I hope one of these games sparks something. Maybe you'll laugh. Maybe you'll get a high score. Maybe you'll think, “I want to make one of these.” If you do, that's the best thing that could happen on this site.
If you're someone learning art or code: please, make stuff. The tools are here. You don't need permission, and you don't need an expensive degree to start. You need curiosity, time, and a few people who believe in you. I'm rooting for you.
