 +For this project, the only puzzle you HAVE to solve in order to be eligible for full credit will be the one contained in the **puzzle** file.
 +
 +Should you desire, there's an opportunity to gain some bonus points, which can be earned by successfully solving and documenting your solution to the puzzle contained within the file **bonus** and reporting it to me as appropriate.
 +
 +As you gear up to work on the project-required puzzle (or additionally the bonus puzzle), I have provided a sampling of practice puzzles that you can try your hand on in order to get more experience working with these type of puzzles. Doing them will not net you any points, nor will not doing them diminish your totals for this project. I would recommend doing them, though, as the more exposure you have within this domain, the more patterns become identified, further facilitating your chances of success.
