Have you tried hellowordl (https://hellowordl.net) where you can play over and over, change the number of letters you use (how big the puzzle is), and so on? It is also free. I thought six letters would be easier than 5. I can think of a lot of 6 letter words. It is very tough, just adding that one letter really ups the number of possible combinations.
Viewing post in well now that i've played this i want more
Being able to change the letters is a cool twist!
But what I meant about continual play, is that you have to use your same clue-words to figure out the new word. So you'd have to balance using clue-words that will help you determine your current word, versus clue-words that will help you solve *any* word. It's nice that hellowordl allows you to keep playing more easily, but it wasn't quite what I was hoping for. Such a great name, though.
