Welcome to this superb collection of 100 circle sudoku puzzles! These puzzles all have their own solution towards the back of the book, so if you get stuck take a look there. Here are some solving tips: Place each number from 1 - 8 exactly once in each of the eight concentric circles that compose the puzzle. In addition, each number from 1 - 8 appears exactly once in each of the eight segments of the circle. Each puzzle has one solution that can be reached through logic alone. That's all there is to it!

What do road and railway systems, electrical circuits, mingling at parties, mazes, family trees, and the internet all have in common? All are networks - either people or places or things that relate and connect to one another. Only relatively recently have mathematicians begun to explore such networks and connections, and their importance has taken everyone by surprise. The mathematics of networks form the basis of many fascinating puzzles and problems, from tic-tac-toe and circular sudoku to the 'Chinese Postman Problem' (can he deliver all his letters without traversing the same street twice?). Peter Higgins shows how such puzzles as well as many real-world phenomena are underpinned by the same deep mathematical structure. Understanding mathematical networks can give us remarkable new insights into them all.

The Sudoku Effect: Universities in the Vicious Circle of Bureaucracy

This book shows that the introduction of the European Credit Transfer System (ECTS) of credit points as a new accounting unit at universities has led to increased bureaucracy and the schoolmaster-style regimentation of Bachelor’s and Master’s courses. It explains how, due to the pressure of having to plan every single working hour of studying in advance, a ‘Sudoku Effect’ is created by the necessity to combine courses, exams and modules in such a way that the points ‘add up’. An unintentional side effect of the introduction of the ECTS, the Sudoku Effect has led to more classroom style teaching, an inflation of exams and fewer choices available to students. It has resulted in such complex and contradictory guidelines for the planning of the curriculum that the values attributed to the higher education reform can often only be realised if the rules for Bachelor’s and Master’s programmes are ignored, or at least stretched, in practice. The book describes how the reaction to this situation is the continuous further refinement of the complicated rules rather than their abolishment.
