Like Worldle, but for Northeastern Illinois (NEIL). Rather than guessing countries, NEILdle is focused on the 284 municipalities that are wholly or partially within the seven counties of Cook, DuPage, Kane, Kendall, Lake, McHenry and Will.
NEILdle is written in R using Shiny. Most code comes from wch/shiny-wordle's implementation of the immensely popular Wordle, but significant modifications have been made so that the game functions more like the geography-based Worldle than the purely word-based Wordle.
