Advanced “Either Or” Clue Solving Part 2

CharlieDec 21, 2017 Playing Tips No Comments

A lot of the Daily Challenge puzzles and Hard level puzzle packs contain games which require a more advanced knowledge of the Either Or clues.

If you look at the puzzle example here, the second part of clue 3 tells us some information that might be hidden to the novice logic puzzler. From this clue, we know that Glasgow and buses are separate events but it also tells us more than this. If you look down the column on the grid you can see the player has already marked Glasgow and Buses as False . . . BUT . . if you carry on down that same column you can see that Glasgow also isn’t equal to Instagram or Cell Phones.

So, looking at the first part of the clue we know that May 14th must be equal to Glasgow or Buses; and we now know that Glasgow isn’t equal to Instagram or Cell Phones and buses isn’t equal to Instagram or Cell Phones as they are in the same section . . it therefore follows that May 14th CANNOT be equal to Instagram or Cell Phones. From a previous clue May 14th and Instagram is already filled in as false but we can now fill in May 14th and Cell Phones as false.

The same process now applies to 6000 (the other item in the first part of clue 3) which also CANNOT equal Instagram or Cell Phones so you can now fill these two boxes as false.

The same process can also be used across the rows as well as the down columns. So where we see Buses and Glasgow is already false, we can also see that Buses are not equal to Birmingham either. So that then tells us that May 14th and 6000 CANNOT equal Birmingham either.

Use this technique every time you see a clue beginning with “Of . . . .” and you’ll be able to solve some of the more difficult puzzles.

Following on from our last playing tips post about Either Or clues, here we will go into another aspect of information that can be gained from these type of clues.

In this puzzle example clue 3 states “Of the show taking place on May 14th and the show that he performed to 6000 people . . .”.

Now if you look at the grid you can see that the show on May 14th has already been confirmed as having 7000 people at it. If you add this piece of information into clue 3 it could now read “Of the shows that he performed to 6000 and 7000 people . . .”

This tells you that the information in the second part of the clue (in this case Glasgow and buses) can only be equal to 6000 or 7000. As a result we can fill the following with an X as being false: Glasgow and 5000, Glasgow and 9000, buses and 5000, buses and 8000, buses and 9000.

In the second part of this blog post we will explain another more complicated way of getting information from “Either Or” clues.
