3) Classic puzzle - magic square 1Around the turn of the 19th/20th century, Sam Loydd was the most famous puzzler in the USA, but in his entire cylopedia i discovered only one domino puzzle, more about that in another issue. Henry Dudeney lived in roughly the same period, and included a separate chapter on domino puzzles in his Amusements in mathematics. And even outside this chapter i found a puzzle on dominoes.
In the table below the som of the dots on the first row is 13. Complete the other 5 rows with the tiles from a double 6 pack in such a way that the sum of all rows, columns and the two diagonals is 13.
4) Classic puzzle - magic square 2
Henry Ernest Dudeney gives the solution the problem above in his book as an example. His real challenge was: make a square of 6x6 such that the sum of all rows, columns and the two main diagonals is 18. En passant he natoes that 23 is also possible.
