UberGogen and UltraGogen Puzzle Books
The UberGogen and UltraGogen puzzles in these books go from: the easiest
you can find on a Monday that take you ten minutes to do; to the hardest ones
that you get on a Sunday - to give you an idea, the one on the left isn't the
hardest I have done and it took me about an hour. Try today's puzzle by clicking Here.
Each book consists of 250 puzzles that are all new, never been published -
125 Uber-Gogen puzzles and 125 Ultra-Gogen puzzles - along with the answers at
the back and, as you would expect, they increase in difficulty as you work
your way through them. You can see on the 'Look inside'
feature on Amazon's website,
what the puzzles look like - they are printed in a 5½"x8½" which
is a bit narrower than DIN A5 paperback format on off-white paper so they are easy on the eye, a good,
practical size and will still fit in your pocket.
So, whether you are a hardened puzzle junkie, someone who wants to become one or you need to find a gift
for somebody that is one, this is the only place you will find them.
Currently, there are four books (a total of 1,000 puzzles) and you can go to each
book's Amazon page by clicking on the country code links below (for example 'UK'). Amazon will send the books you order to any address you specify (and wrap them as gifts if you want them to).
How do I know that all of the puzzles are new? Well, I don't know with absolute
certainty but it's a guess with pretty good odds. With a dozen layouts used and
eliminating mirrors and rotations, that makes 23,266,815,064,996,478,976,000,000
combinations which is about the same as:
- The number of millimetres from Earth to the Andromeda galaxy;
- Roughly the number of water molecules in two 350ml cups of coffee;
- If you were able to stretch that many gold atoms to make a filament that
was only one atom thick, it would be 3,955,358,561,049km long which would take
light 5 months to travel;
- The number of cubic millimetres (microlitres) of ice in the Antarctic ice cap
(that would give a sea-level rise of around 58m or 190 feet drowning Nottingham
and Manchester but giving rise to the new Port of Leicester); or,
- The proportion of times you would lose the UK Natonal Lottery
if instead of choosing 6 correct balls from 59 (and that is up from the 6 correct
balls from 49 where the half hour program where you watched them perform the
draw gave rise to a situation were you stood a greater chance of dying of a
heart attack whilst watching the program than you did of winning it) you
had to choose 29 correct balls from a total of 102.
