This book is composed of the most interesting problems from a quarter
century of regional mathematics competitions for students aged 11-14 in
the province of Styria, Austria. The problems presented here range from
pure puzzles to a more traditional mathematical type of question, but
all are somehow special, posed with the intent of giving the reader
something interesting to think about, with the promise of an
entertaining moment of elucidation and enlightenment at the end.
