Puzzle 1
Can you find the country hidden in the following paragraph?
Welsh horses are my favourite animal. Tapir, llama, marmoset, and elephant closely follow. I don't care much for English rabbits nor ocelots, adders, goldfish, and spaniels.
Puzzle 2
The river Pregel ran through the town of Konigsberg. In the river were two islands, connected to each other and the rest of the city by seven bridges.
The residents of Konigsberg challenged each other to walk through the city, and cross each of the seven bridges exactly once.
Can you find a path that they might have taken?
This is the 'Seven Bridges of Konigsberg' puzzle, tackled by Leonhard Euler in 1736.
Puzzle 3
Last week my wife and I found ourselves stranded on an island, oops!
Unfortunately, we were also stranded with our two sons, with no clear means of rescue.
Luckily, I came across an old rickety boat which I knew could carry either one adult or two children.
How did I rescue my family?
