DARIO DE TOFFOLI (Venice, 1953) has been travelling far and wide through the ludic universe for some forty years : he writes books and articles, invents games, organises events and, above all, he plays (and often wins !). To him, numbers and calculation are instruments of a beautiful game, one that helps us keep our brains fit and think better.
 
He is the founder of studiogiochi and the creator of the Premio Archimede for unpublished games ; he also was Pentamind World Champion in 2002 and in 2012.
 
He is the author of Il grande libro del calcolo veloce e mentale, published in Italy by Kangourou and Mondadori.
 
In the meeting he will make you play with fast calculation and mental calculation, to emphasise that what counts most – even more than knowledge of specific algorithms – is mental flexibility. By finding the right shortcut, one can solve apparently impossible calculations.
