Did you know that your brain needs exercising in order to function effectively, let it go and your mental processing can become sluggish. All too often we get bogged down by the mundane and fall into the same patterns of thinking that lead us to the same results day after day.

The following 50 brain teasers will not only get your grey matter working but for some of them you will really need to think “out of the box” to work them out and in doing so you will be able to create new neural pathways leading to better problem solving abilities and a wider perspective on life in general.

1 EINSTEIN’S RIDDLE

Here is one only for the bravest of you. Einstein said that 98% of the world would NOT be able to solve this puzzle. Can you? The trick is to be patient and to pay attention to the details.

There are 5 houses in 5 different colours in a row. In each house lives a person with a different nationality. The 5 owners drink a certain type of beverage, smoke a certain brand of cigar, and keep a certain pet. No owners have the same pet, smoke the same brand of cigar, or drink the same beverage. Clues:

1. The Brit lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the immediate left of the white house.
5. The green house’s owner drinks coffee.
6. The owner who smokes Pall Mall rears birds.
7. The owner of the yellow house smokes Dunhill.
8. The owner living in the centre house drinks milk.
9. The Norwegian lives in the first house.
10. The owner who smokes Blends lives next to the one who keeps cats.
11. The owner who keeps the horse lives next to the one who smokes Dunhill.
12. The owner who smokes Bluemasters drinks beer.
13. The German smokes Prince.

7/You can only run half way into the woods otherwise you’ll be running out of the woods

8/It is a grandfather, his son and his grandson

9/You got the number 18 because it doesn’t matter what number you start with at the beginning, this problem is more of an illusion as the “unknown” number has been calculated mathematically to reach 18.

11/He had hiccups

12/The poison was in the ice cubes and in the king’s case didn’t have time to melt fully into the drink

13/A candle and matches and the light filled the entire room

29/There are 9 left as all but 9 have died

30/The word is incorrectly because it is always pronounced incorrectly

31/ The snail reaches the top of the pit on the 16th day!…On the first day, the snail reaches a height of 5 meters and slides down 4 meters at night, and thus ends at a height of 1 meter. On the second day, he reaches 6 meters, but slides back to 2 meters. On the third day, he reaches 7 meters, but slides back to 3 meters. On the fifteenth day, he reaches 19 meters, but slides back to 15 meters.

49/Just throw the ball straight up into the air

50 /This one is misleading to start with as there is no missing pound. The actual amount paid out is £27, minus the £2 for the hotel assistant makes £25. It’s only because the numbers are so close to £30 that it is confusing.
