TRAFFIC LIGHTS app for iPhone and iPad

The Traffic Lights game is a great way to give your child an understanding of place value at the same time as helping them to develop logical thinking.
The iPad chooses a secret number and the player has only six guesses to find it. The Traffic Light clues show that the guess has:

GREEN: The right digit in the right place of the secret number

ORANGE: The right digit, but in the wrong place of the secret number

RED: The wrong digit and so not anywhere in the secret number

There are three levels, using 4-digit, 5-digit and 6-digit secret numbers. Just as you feel safe at one level, it’s time to go on to the next.
