The game board is fully interactive. When you select a number, it will disappear, leaving only the remaining numbers in the game. There is also a scoreboard so the students can keep track of the number of questions they have asked.

Directions for play are included, but here's a quick rundown...
Player 1 chooses a number, but doesn't say what it is.
Player 2 asks questions until he has eliminated all other numbers.
The types of questions asked are up to the teacher/student.
Example: "Is the mystery number an even number?"
Example: "Is the mystery number a prime number?"

Students absolutely love this game! I sometimes use it whole class, but more often than not, they are using it as a center activity on my smart board. It will work just fine on a regular computer, too!
