Choose your topic. You have several chances to guess each word. After each guess, the computer helps you by putting one letter in the correct place. There is also a scrambled sentence to give you a clue. Please note this site is American, so 'football' refers to American football.
This will really test and stretch your vocabulary! You will be shown two synonyms, one of which is scrambled. It's a race against the clock to unscramble the word by dragging and dropping the letters. Be warned, though: most of the synonyms are not obvious.
This is similar to Thesaurus Tangle but slightly less difficult. You will be shown a topic, and the scrambled word will belong to that topic. Good luck!
