The book of codes was produced by a novel and complex computer program written to find all solutions to all sub-combinations of a superset of puzzle pieces. It then aggregates the solution count for each piece code and sorts the results according to increasing level of counts. It is expected that over the next few years, the results will be checked by both players and programmers.
Players will be able to check the low-count codes by tweeting solutions and comparing other tweets for the same code. A special case is to try to find a solution for a code that is not in the book. There should be no solutions for these cases. An innocuous error has been inserted into the code book for all sets sold. See if you can figure out what the error is before it is revealed in 2017!
Programmers will be able to check low-count or high-count codes by writing their own program or using an available program such as Scott Kurowski’s.
