Together, the Startdl puzzles are a solid, well-rounded package that will appeal to a broad variety of puzzling tastes. This grouping includes games for number people, word-lovers and code breakers. While these puzzles work very well as a team, they can also be purchased individually.

Add Them Up: It's a crossword puzzle for all the number people out there! You will find not one single letter in the completed grid of an Add Them Up puzzle. Instead, each "word" in the solution is a number whose digits add up to the sum given in the clue, and no "word" contains any digit (0 through 9) more than once.
