Puzzle 821 


Four shepherds were watching over their flocks, and they were commenting on how many sheep they each had.

If Alex had three more sheep, then he'd have one fewer sheep than Billie.

Whereas Drew has the same number as the other three shepherds put together.

If Charlie had three fewer sheep, he'd have exactly three times the number of Alex.

If they were evenly distributed, they'd each have eleven sheep.

How many sheep does Alex have?

Puzzle 822 


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?

Two islands, one bridge joining. One also has two N, two S. The other also has one N, one S.

This is the 'Seven Bridges of Konigsberg' puzzle, tackled by Leonhard Euler in 1736.
