In the early 2000's, I enjoyed flash games and created three flash arcades:

https://www.eskimo.com/eskimo-arcade/
http://www.ybbored.com/
http://www.defender-games.net/

Note that ybboared and defender-games is presently not https, this is because when flash was discontinued in 2020, I did not renew the certificate.

Now I've resurrected these arcades using ruffle. Ruffle is open source software that translates shockwave files into webassembly which your browser can execute without flash.

Check it out, have fun, remember presently ybbored and defender-games have no SSL but certs are on order.
