Yup, mostly surprised by the longevity of the website (1992-today). And of course being able to play it online

I wonder how it would work before Javascript.

HTTP POST can handle this readily. I'm guessing a frameset with targets circa late 90s based on the current layout

Was it always a website?

In 1992 it would have more likely been a telnet service.

This is also very achievable in hypercard or visual basic so it could have also been a downloadable application

I've got a Next and an HPUX so I've tried the early browsers and written code for them. (HPUX is for ViolaWWW) They're pretty buggy. Making them handle the game would take some serious work

now that i'm in front of a computer i can see it was registered in 2005. The 1992 is not related to the website but to the game.

I guess also the inspiration for the hit television program "Deal or No Deal."

Can't Stop and Can't Stop Express are mainstays of my family's COVID-era weekly game night on Board Game Arena.

Board Game Arena has a free implementation of Can't Stop with multi-player match making.
