I believe I have found the best board game for the ESL classroom. It's Guess Who.
This game has always been popular, and it is an excellent game for ESL students.
Guess Who allows students to practice question forms, specifically yes/no questions.
Each player chooses a card with a character name and face on it. Then the players take turns asking yes/no questions to try and guess who the character is. Each person has a board with all the characters on it that they use keep track of the characters.
Formulating yes/no questions is incredibly important, and it is not always easy for ESL students. This game really let's them practice. Some common questions:
Does he have a mustache?
Does she have red hair?
Is he bald?
Is it a woman?
Does she wear glasses?
Apart from asking yes/no questions, it is also helpful for face vocabulary like beard, mustache, lips, eyes, etc.

Guess Who is fun and gives a focus on form. It makes a great ESL game for any classroom.
