Random information on the term “Number puzzle”:
A cross-figure (also variously called cross number puzzle or figure logic) is a puzzle similar to a crossword in structure, but with entries that consist of numbers rather than words, where individual digits are entered in the blank cells. The numbers can be clued in various ways:
Cross-figures that use mostly the first type of clue may be used for educational purposes, but most enthusiasts would agree that this clue type should be used rarely, if at all. Without this type a cross-figure may superficially seem to be impossible to solve, since no answer can apparently be filled in until another has first been found, which without the first type of clue appears impossible. However, if a different approach is adopted where, instead of trying to find complete answers (as would be done for a crossword) one gradually narrows down the possibilities for individual cells (or, in some cases, whole answers) then the problem becomes tractable. For example, if 12 across and 7 down both have three digits and the clue for 12 across is “7 down times 2”, one can work out that (i) the last digit of 12 across must be even, (ii) the first digit of 7 down must be 1, 2, 3 or 4, and (iii) the first digit of 12 across must be between 2 and 9 inclusive. (It is an implicit rule of cross-figures that numbers cannot start with 0; however, some puzzles explicitly allow this) By continuing to apply this sort of argument, a solution can eventually be found. Another implicit rule of cross-figures is that no two answers should be the same (in cross-figures allowing numbers to start with 0, 0123 and 123 may be considered different.)
