Sixty is an online vocabulary builder that supplements existing foreign language learning programs.  The premise is this:  if you learn 2,000 words, you’ll know 60% of a language.  Conversational vocabulary is possible in three easy steps:

  1. See, hear, and type the word.

  2. Guess the word in seven seconds.  

  3. If you guess the word correctly, you’ll see the word less often.  If you guess incorrectly, you’ll see it more often.  

Our game strips the chaos out of learning vocabulary.  We adapt to each user’s learning curve, so students who use our system for just 20 minutes a day, learn 2,000 words in less than three months.
