How to Play Semaphore

 

You have to find a number with no repeating digits using the following color clues:

. no digit is correct 

. one digit is correct, but in the wrong position

. one digit is correct, and in the correct position

​

For example, from the following clues

1  8  7   ..

​

we learn that two of the digits of 187 belong to the number we are looking for, with one digit already in the correct place value and the other in the wrong place value.

 

The order of the color codes does not have to match the order of the corresponding digits in the given number. More than one answer is possible!
