What this is

A small collection of games made at home. Every one runs straight in the browser, works on a phone or tablet, and can be installed to a home screen to play offline.

No accounts, no advertising, no tracking of any kind. Nothing a child does here leaves their own device — see the privacy page.

More coming

New games get added as they are finished. Ideas are welcome, especially from the people they are made for.
