These collections comprise 25 original puzzles in large format (15x15) grids and cost just £3 each. They come in the form of PDF files of just over 500kB so downloading time should be kept to a minimum. Clicking on the image of the collection you wish to buy will take you to my Etsy shop where you can complete your purchase. New collections will be added on a quarterly basis with volume four scheduled for release in April.
Please note: these collections are not merely puzzles from the old archive that have been bundled together in sets of 25; they are wholly original and have been created exclusively for this enterprise.
