## Game Board

## Rules

Group students in pairs and have them work on the same Polypad game board.

- First, player 1 creates a four-digit code using the numbers 0-9 and hides code behind the red rectangle. Some options to consider:
- You can limit the numbers (For example 1-6) according to the students' grade level.
- You may decide whether the repetition is allowed or not and inform the students. You may want to increase the number of guesses allowed respectively.

- Player 2, The Code Breaker, starts with a guess by dragging the number cards to the first row.
- Player 1 evaluates the first guess by dragging the squares onto the numbers in the guess.
- The red square indicates the guess is correct and also in the correct place.
- The blue square indicates the guess is correct, but not in the correct place.
- The purple square indicates an incorrect guess (Both the number and the place).

- The Code Breaker has 6 guesses to break the code.
