Expansion Pack: A Crossword Suite
A crossword puzzle suite with nine puzzles of all sizes (3x3, 5x5, all the way to 17x17). Expect puzzles of all kinds of difficulties from easy to fiendish, and some twists and tricks along the way.
The main part of this suite is available for FREE (pay-what-you-want if you're so inclined), but for $10 you can get Expansion Pack XL, which has everything in the normal suite plus a bonus 21x21 themeless! Just select Expansion Pack XL when you check out, and you'll get the ~deluxe~ experience!
