The main distinction between Hogwartle and Wordle is that the Harry Potter canon is used exclusively for both the source and solution word lists in Hogwartle. Wordle is an exact clone of Hogwartle. In every other respect, the gameplay is identical to that of the classic version of the game. You are entering words that have five letters each. The color of the light that emanates from each letter is determined by whether or not it is the final letter of the word. There is a strict prohibition on the use of plurals.
Because only Harry Potter-related words can be used as guesses or answers, it's possible that you won't make it past the first guess if you don't have a serious Potterverse reference book on hand.
