Overview System Requirements


Number Fill-Ins are Fill-In puzzles with a delightful difference - each puzzle consists entirely of numbers! No math skills required, and just like regular Word Fill-Ins all the entries are provided. You solve each puzzle by filling in the diagram with entries reading across and down, in the same manner as a crossword puzzle. Across and Down answers are mixed together, and it is up to you to find their proper places in the diagram. To help you get started, one entry in every puzzle is already filled in.
