wordle unlimited is a free online game based on the famous Wordle game. This game allows you to guess a secret word of five letters by entering suggestions and getting feedback on how many letters are right and wrong. You can play with English or Vietnamese words, and you can choose the difficulty of secret words. You can also create your own secret words and share them with friends. I tried to play Wordle Unlimited and found it very interesting and challenging. I've learned a lot of new words and how to distinguish between letters in English and Vietnamese. I've also tried to guess the secret words made by other people, and I'm very happy to guess. I think this is a very good game for training your memory, improving your vocabulary, and developing logical thinking.
