There are several of this type of puzzle that have been around for years, but we think this pair of linked puzzles are amongst the best.
Both concern three different coloured boxes, which are red, white and blue, where one of the boxes contains a prize. Each of the boxes is labelled with a statement and from these statements you must deduce which box contains the prize.
In the first puzzle the boxes are labelled thus:
- Red Box - The prize is not in the Blue Box.
- White Box - The prize is not in this Box.
- Blue Box - The prize is in this Box.
Of these three statements, no more than one is true. So, where is the prize?
In the second puzzle the boxes are labelled thus:
- Red Box - The prize is not in the White Box.
- White Box - The prize is not in this Box.
- Blue Box - The prize is in this Box.
Of these three statements, one or more is true and one or more is untrue. So, where is the prize?
As usual you can post the answers as a comment on this website, reply to the post on Facebook, or retweet or reply on Twitter @quizmastershop.
