Hey I Found something and sense you also seem to be trying this and made some progress I wanted to share something I found. In this game the number/780 is made after 30 letters are said. The last 780 is 30*26 because of 30 letters with 26 in the alphabet. The first number is weird you have to assign a number value. A=1 B=2 etc but dont include repeats and that equals the first number. Hopefully this helps you make progress if you find anything it would be awesome if you could share
