If you are used to doing code word puzzles where one letter of the alphabet is substituted for another and you want something a little more challenging you will find it right here. Letters, numbers and symbols are used to create the code and there are usually no patterns to the code. So, just because 10 might represent M it doesn't mean that 11 will represent N. Clues are provided for each puzzle to get you started.
Here’s your chance to show how smart you are.
There are hours of fun to be had with this little book, with different levels of difficulty to provide something for everyone.
