Most quick crossword books require users to find their way to the relevant very large category groups, then work their way through to the relevant section, and then again to the required word. This new Crossword Solver is based on the principle that there is no actual advantage in these large categories. If the clue asks for the name of a river and the solver doesn't know it, how does the category of Rivers help? It doesn't! Our new approach is now entirely practical and works every time for its crossword reader/user.
