Fun, Puzzles, Travel
Written by Paul Bourke
The following are a number of puzzles presented for your entertainment.
Feel free to submit any puzzles that you think are interesting,
my email address can be found here.
If appropriate I will include them here.
The main requirement for any puzzles listed here is they should not
require any advanced mathematical skills. If you find yourself
writing equations for any of the puzzles you are probably approaching
it the wrong way. (There are only a couple of exceptions below)
The puzzles below are approximately in order of increased difficulty
although it is only my own personal impression.
To answer your next question, no, answers are not provided
to most of the problems.
The whole point of a good puzzle is for it to prey on your mind
until you solve it.
If you are REALLY desperate I will reveal answers if you
beg or for a small inducement (eg: beer, chocolates, postcard).

Contrary to what most people say, the most dangerous animal in the world
is not the lion or the tiger or even the elephant. It's a shark riding
on an elephant's back, just trampling and eating everything they see.
