Sunverse (the map is called Sunfield) is a free learning game for kids roughly ages 6–10. Four worlds cover math, reading & grammar, space and money. There are also nine arcade mini-games, a garden that grows as lessons get finished, and a collection of Sproutlings that hatch as you play.
It is a practice game, not a curriculum. It is meant to sit alongside school, never to replace it.
Sunverse is built and run by ISSMCSP — a small, dad-operated project. One grown-up makes it, tests it on his own kids, and answers the mail himself.
There is no paid tier and no subscription. Sunverse has no ads, no third-party trackers, and no in-app purchases. There is nothing for sale, so nothing can be sold to you later.
Everything your child does is saved in that one browser, on that one device. It is never sent anywhere during normal play. See the privacy page for exactly what that means, and the terms for the ground rules.
Sunverse is free for personal, family and classroom use. It works offline once loaded, and it can be installed as an app on a phone, tablet or laptop. There is no chat, no friend list, and no way for another person to contact your child through it.
