I would like the neighborhood’s suggestions on a puzzle I’m contemplating creating.

_{If your reply is actual brief, a remark is okay. Otherwise, please depart an actual reply.}

Let’s say the solver is given, as one of many earlier levels in a puzzle, many units of two phrases that must be linked collectively. One set, for instance, may be

iron ______ ______ spray

and one wants to determine the linking phrases as follows:

iron abdomen bug spray

the place “iron abdomen”, “abdomen bug”, and “bug spray” are all recognized issues.

I’m strongly contemplating together with a examine sum for each reply affirmation and likewise to stop (hopefully) the solver from making an attempt to maneuver to the subsequent stage with a solution that is not the meant reply, however which may additionally match (nevertheless unlikely).

For the instance above, the examine sum would appear to be this:

iron abdomen bug spray examine sums: 27, 9

the place 27 is the sum of the A1Z26 values for the primary and final letter of the anticipated reply:
For “abdomen”, s(19) + h(8) is 27, and for “bug”, b(2) + g(7) is 9.

It’s exceedingly unlikely that an unintended reply would cross the examine sum additionally.

The query:
Is this fascinating? Is it useful? Too useful? Annoying? Overkill? Not sufficient? Other recommendations or concepts are welcome.
