Secret Code

15 min2 participants

Implementation of a multiple-step strategy designed to ask appropriate questions and guess a 3-digit secret number.

Let's play!

  1. Player 1 : Write a secret number using 3 or less bricks, on your base plate.

  2. Player 2 : Guess the secret number by asking relevant questions: e.g. How many bricks are used? Is it an even number? Is the number in the tens place odd or even? Does it start with a 7? Is it higher or lower than 500?

How to prepare

  • 2 base plates

  • Number bricks

  • 2 number sign brick

  • 1 bowl

Place the number sign brick in the top left corner of each base plate to indicate the bricks are numbers.

Place the remaining bricks in a bowl to share.

Give a base plate to each player.

Facilitation tips

  • Suggest manipulation of bricks.

  • Discuss strategy: “How can you remember all of your questions and answers?”, “Which questions work best?”.

Possible variations

  • Determine a time limit or a maximum number of questions.

  • Increase the number of players: more than one player asks questions.

  • Increase the number of bricks in the secret code.
