1. The Camels

Four tasmanian camels traveling on a very narrow ledge encounter four tasmanian camels coming the other way.

As everyone knows, tasmanian camels never go backwards, especially when on a precarious ledge. The camels will climb over each other, but only if there is a camel sized space on the other side.

The camels didn't see each other until there was only exactly one camel's width between the two groups.

How can all camels pass, allowing both groups to go on their way, without any camel reversing?

Hint:

Use match sticks or coins to simulate the puzzle.

Solution:

First a camel from one side moves forward, then two camels from the other side move forward, then three camels from the first side move forward etc...

The answers given all fit the following rule: After eliminating the lowest and highest numbers shown, sum the remaining odd dice and take the highest even number below that (or zero if there is none).

Some puzzles' solutions are not given, for example, the first puzzle.

I have a more elegant solution to the tasmanian camel problem. It was indicated that the camels would climb over each other "only if there is a camel sized space on the other side." It was not specified, however, that the "other side" was to occur after only one camel length.

You could also consider the perfect mate and leave your friend who saved your life with the old lady. If your friend saved your life once, they might do it again.

An alternate solution to the camel problem is that a camel should be able to climb over multiple camels before coming to the empty slot.

The solution suggests picking from the box labeled 'Apples & Oranges', but it doesn't guarantee that the box contains only apples or only oranges. It could contain both, leading to confusion.

The puzzle was frustrating and not enjoyable.

The solution to the puzzle is to give the keys to your friend first, who can drive the lady home, avoiding unnecessary trips.

As a Tasmanian, I want to point out that camels don't live in Tasmania.

The riddle states, 'I am a drink and I rhyme with toffee.' The answer is likely 'coffee'.

There are mistakes in your puzzles and solutions. I found errors in 3 out of 10 puzzles I tried, including the example of the Tasmanian camels.

120 wires x 10km each makes only 1,200 km, not 12,000 km.

There are alternative explanations for the puzzles, such as the mother keeping birthday presents in the cellar or being involved in other activities.

There is no such thing as a Tasmanian camel....

The camel puzzle in the 'very easy' section was difficult for my students. We would like to revisit it, but it seems to be inaccessible now.

The camel puzzle in the 'very easy' section is currently inaccessible. My class has been looking forward to solving it, and I would appreciate it if you could send me the puzzle and its solution.
