Project: WEEKLY PUZZLE FUN (wpfC)

Part 1: 7x7 challenging logic-grid puzzle

Objective

To apply your skills in the solving of a logic puzzle. We've now been through the gamut of resolutions on easy and medium difficulty. You'll find the clues may reveal fewer direct things, while really cranking up on the indirect- this is where the connections will be made.

Grid-Based Puzzle Strategies

Some things to keep in mind when solving this type of puzzle:

Remember, keeping track of what has been eliminated is just as important as tracking what has been identified. A lot of trouble or “dead ends” have emerged when people were not keeping full inventory on grid box eliminations.

Please do endeavor to put forth original, honest effort in the solving of these puzzles, by hand; the process will help foster and solidify many analytical reasoning skills that will influence and improve your logic and programming skills. Improvements won't happen overnight, but through consistent practice, by the end of the semester you should start reaping the benefits of such an activity.

Puzzle Backstory

The Byronville Gaming Club holds one “game night” each month, at which a number of members gather to play a different board game.

Part 2: Letter Division Puzzle

Objective

Logic grids are not the only form of logic puzzle; here is another one that relies heavily on logic and reasoning in order to sift through.

A letter division puzzle is one where the numbers 0-9 have been replaced with various letters of the alphabet; it is your task to determine what number each letter maps to, and report that to me in the project submission.

Letter Division Puzzle Strategies

Some things to keep in mind when solving this type of puzzle:

As I said: For this sort of problem, you will likely want to take notes; all the various little tests you concoct to prove or disprove some relationship can be important in the bigger picture. This may also take a bit longer and seem more overwhelming (especially at first), but really, it is just longhand math :) Remember to attack the problem in pieces, and not head-on all-at-once.

Practice some similar math problems to derive patterns so that the seemingly unfamiliar letters performing math can start to make more sense.

Part 3: Sudoku puzzle

Objective

With the logic grids you put your logic skills to the test, with the word math you math skills. Here, we will explore various other types of puzzles, often combining both logic and math skills to solve, but also exercising different aspects of your deduction/induction skills.

Puzzle

Enter numbers into the blank spaces so that each row, column and 3×3 box contains the full sequence of numbers 1 to 9.

Top row:

pos #0 pos #1 pos #2 pos #3 pos #4 pos #5 pos #6 pos #7 pos #8
