So, the author gave the model single sentence prompts like "Balatro, but for the game of coin flips" plus generic encouragement like "make it better" three times ended up with netlify-hostable web games each time? That is hard for me to believe.
It's likely that at least some amount of additional context was provided to the model to enable it to reliably create the desired form factor. This introduces the caveat that the author probably views some amount of context as being trivial / beneath the level of mentioning. But then the question becomes where they draw the line.
