The games on this site are free to play in your browser. They are provided as-is, the site is supported by advertising, and the simulations are for learning and fun, not for real engineering or safety decisions. By using the site you agree to these terms.
Some games model real systems: flood defense, dam and spillway operation, eclipse paths, orbital mechanics and others. They are built carefully, but they simplify the real world and are meant for education and entertainment. Do not use them to design structures, operate facilities, plan an emergency response, or plan eclipse travel without checking authoritative sources. Nothing on this site is engineering, financial or safety advice.
The game source code is published on GitHub under the MIT License, which sets out what you may do with the code. Game names, artwork and the written text on these pages remain the property of their author unless stated otherwise. Classic games such as Chess, Go and Solitaire are traditional games; their rules belong to no one, and the versions here are original implementations.
The site shows advertisements served by Google AdSense, and some pages link to other sites, including app stores and itch.io. We are not responsible for the content of third-party ads or sites. How advertising uses cookies is described in the privacy policy.
The site and games are provided "as is", without warranty of any kind. Games may change, be removed, or be unavailable at times. To the extent the law allows, the author is not liable for any loss arising from use of the site.
These terms may be updated; the date above shows the latest version. Questions: see the contact page or email michaelbflynn@gmail.com.
