For fans of this cult Japanese puzzle here are 365 fiendish sudokus which require all your powers of logic, endurance and concentration to be rewarded with hours of brain-twisting fun. A challenge for every day of the year, this softback book has one clear big puzzle in an elegant layout with an elastic fastener and a full size bright white pencil with a rubber tip slotted into an elastic fastener down the side, so when you change your mind you can easily erase and make your second or third (or fourth) attempt. Mind bending fun with numbers, beautifully decorated cover with black background and pale pink flowers and berries, birds and leaves design for a lovely gift idea.
