Got an undeciphered writing system you can't read? No problem! Here's how to start cracking a lost script: use your digits. I figured it was time to reconvene the Decipherment Club for this one. As Robinson points out in the introduction to Lost Languages, counting the number of distinct glyphs in an undeciphered text is a convenient trick to keep in mind when you start deciphering a writing system. Linguists and decipherers have been using it since at least the days of Assyriologist AH Sayce. In principle, it's a simple little algorithm that we can use to make an educated guess about the type of writing system used in a lost text. You can get a feel for this simplicity in my short code demo at the end.
