24th volume of the book series “Sfide e giochi matematici”, in 60 volumes, published between 2017 and 2018. studiogiochi wrote the presentations for the whole series.

This volume offers some nice logical, mathematical and intellectual brain-food, with no risk of surfeit whatsoever. From classic logical problems to never-before published brain teasers, from intelligence tests and numerical quiz to measurement comparisons, the adventure continues, among original and endearing problems, taken from contemporary board games. Last but not least, there is obviously a section dedicated to Sudoku, with new schemes, curiosities and variants.
