If you like to play Wordle - there is a great website called mywordle.me that allows you to easily create your own Wordles to share with others. I created a blog post as well - How to create your own custom Wordle.
Flippity.net has included the game called Word Master. ** Make sure to check out all of Flippity's other options as well - it is an outstanding site.**
Word Master is very similar to Wordle with a few minor tweaks. You can see the differences below:
Important differences from Wordle:
There is no dictionary. Players may type whatever the wish, including gibberish.
There is no standard character set. You may use numbers, symbols, and non-English characters in your puzzles (but players will need to be able to type those characters.)
You may use words of any length up to 10 characters. 5 character words are recommended.
