One person selects a string of four items from a set of 8 and the other guesses the string of 4 each time. In the four boxes to the right of the guess the first player then gives clues to improve the guess by using one of three different symbols, and open circle, a closed circle and an empty box.
The closed circle means that letter or number is correct and in the correct place, then open circle means that the number is correct but in the incorrect place and the empty square means that the number is not correct.
Play continues with the second player continuing to guess until they have either correctly identified the string of four letters or number or until they have run out of guesses.
Choose eight numbers; for example 1-8
Choose who is who. One player becomes the codemaker, the other is the codebreaker
Choose 4 numbers. The code maker chooses a pattern of four different numbers; for example 1 2 3 4.
Try guessing the pattern. The codebreaker tries to guess the pattern, in both order and number, within twelve (or ten, or eight) turns. Each guess is made by writing a row of four numbers.
Provide feedback. After each guess the code maker provides feedback by placing from zero to four key dots next to the guess.
Create a response code. A full key dot is placed for each code number from the guess which is correct in both number and position. An empty dot indicates the existence of a correct number placed in the wrong position. Put first the empty dots and secondly the full ones.
Keep making guesses. Once feedback is provided, another guess is made; guesses and feedback continue to alternate until either the codebreaker guesses correctly, or twelve (or ten, or eight) incorrect guesses are made.
Score. The codemaker gets one point for each guess a codebreaker makes. An extra point is earned by the codemaker if the codebreaker doesn't guess the pattern exactly in the last guess. The winner is the one who has the most points after the agreed-upon number of games are played.
