A census taker approaches a woman leaning on her gate, number 14, and asks about her children. She says, "I have three children and the product of their ages is seventy–two. The sum of their ages is the number on this gate." The census taker does some calculation and claims not to have enough information.
The clue may require arithmetic to be applied to another answer or answers (e.g. "25 across times 3" or "9 down minus 3 across") The clue may indicate possible answers but make it impossible to give the correct one without using crosslights (e.g. "A prime number") One answer may be related to another in a non-determinate way (e.g.
The solution has X and Y as 4 and 13, with P initially knowing the product is 52 and S knowing the sum is 17. Initially P does not know the solution, since 52 = 4 × 13 = 2 × 26. and S knows that P does not know the solution since all the possible sums to 17 within the constraints produce similarly ambiguous products.
This is a common procedure in mathematics, used to reduce fractions or calculate a value for a given variable in a fraction. If we have an equation =, where x is a variable we are interested in solving for, we can use cross-multiplication to determine that =.
A "box technique" can also be applied on occasion, when the geometry of the unfilled white cells at any given stage of solving lends itself to it: by summing the clues for a series of horizontal entries (subtracting out the values of any digits already added to those entries) and subtracting the clues for a mostly overlapping series of vertical ...
Players who answer correctly on the earliest clue get more points than players that answer after more clues are given. The first clue is worth 6 points, the second is worth 4 points, and the third is worth 2 points. The 6 point clue is the hardest clue, while the 4 point and 2 point clues get progressively easier.
