Lucydoku - Paperback
This is Lucy Audrin's first book of 100 sudoku puzzles. Choose standard paperback binding or spiral binding that lies flat. The dry-erase kit includes an 8x10" sheet of thin acrylic, and one each of black, blue, and red fine-tip dry-erase markers. Physical stock from this store will be autographed by the creator, and every copy comes with a sudoku-themed bookmark while supplies last.
