From publisher's website:

Lexogon One is the same, addicting, word-finding game as Lexogon™, but designed especially for the vocabulary and spelling levels expected of middle-schoolers. As with Lexogon, everyone plays all the time. It’s great for intergenerational play, it’s an exciting game for family night play (or for occasions when players want an easier challenge than Lexogon). And teachers see Lexogon One as a great addition for their spelling and vocabulary sections. Kids give it a great learning testimonial. A typical comment from a fourth grader – “I can’t believe I’m learning something and having fun at the same time."
