What is Logic?
A system of reasoning, the art of applying reasoning to the structure and content, the method of deduction. Puzzles like this, where we are given a grid and a list of premises and asked what can be deduced from them, are commonly referred to as Logic 'grid' puzzles.
A format in which the set-up to a scenario is given, as well as the object (for example, determine who brought what dog to a dog show, and what breed each dog was), certain clues are given ("neither Misty nor Rex is the German Shepherd"), and then the reader fills out a matrix with the clues and attempts to deduce the solution.
What makes grid puzzles unique is that the solver is usually provided a grid
( see our example below entitled "My Little Ponies") with all of the given information
arranged neatly in the columns and rows , followed by a list of clues. The goal or
objective is of course to 'Deduce' from the given clues the unique solution to the puzzle.
Please follow along as we now provide a detailed step-by-step analysis of a standard logic puzzle.
MY LITTLE PONIES(SOLUTION)
Last weekend three friends (one named Polly), took their ponies (one named Giggles ), to the pony show, where each of them won a prize (one was a winner). From the clues provided , can you puzzle out , which girl and which pony was the winner and which girls took the other prizes? CLUES: 1. Pam's pony was not named Sierra, the pony that did not win. 2. Giggles won the second prize (place). 3. Polly’s pony was the winner. Pam's pony finished ahead of Penny's. |

USING THE GRID : ( TIPS/STRATEGY)Again refer to the example below. "My Little Ponies", the first clue is given as: ' Pam's pony was not named Sierra, the pony that did not win.' We actually have two deductions here
So locate the row with 'Pam' and the column with 'Sierra' and place an "X" in this box. Now ,locate the row with 'Sierra' and the column with 'Win' and place an "X" in that box. |
|
The next clue is : 'Giggles won second prize ( place)' So locate Giggles's row and the column with 'Place', but this time enter a "Check mark" or some other suitable object to show that this is a positive result, ( while simultaneously placing 'XX' in the Row For Giggles - Win and Giggle - Show, as shown in the diagram to the right). Now ( as a result of this clue ) , neither Sierra nor Patches could be second ( Place ) - so we would also place "XX" in those boxes where Sierra and Patches intersect with 'Place' column. Looking at the Sierra Row we find that Sierra must have finished third ( since we have already eliminated her from 1st and 2nd places ) , so place a 'Green box' in the grid at Sierra -Show ( as shown) . |
|
We can now conclude the order of finish of the horses ( because the only possible grid square remaining is 'PATCHES -WIN ' ) as 1st-(Win)-Patches, 2nd-(Place)-Giggles, 3rd-(Show)-Sierra. ( Check or "XX" the appropriate boxes). Also place an "XX" in the box for Pam under Show ( since Sierra was third , Pam could not finish third ).Your chart should now look similar to this one to the right . |
|
Finally , we have clue #3 ' Polly's pony was the winner . Pam's pony finished ahead of Penny's. ' ( This clue tells us the order of finish of the three girls, as follows ) : (1) If Polly's pony was the winner, Polly must be riding "Patches". (all elimination boxes in Polly's row , Win column and Patches column are shown) and , (2) Pam finished before Penny, so Pam was riding Giggles, and must have Placed (see diagram ). which , (3) Can only mean , Penny was on Sierra. ( From which it follows that Penny finished in 3rd (SHOW) , which is shown below in the final solution diagram ) |
|
In Summary , (also see diagram to the right) we have the solution : 1st - (WIN) - Patches, Polly . 2nd - (Place) - Giggles, Pam. 3rd - (Show) - Sierra, Penny. |
