In one of their online magazine posts FDJ or Française des Jeux reveal some secrets behind the France Lotto balls.
“LOTO® balls are famous and hold secrets! From their weight to their size, including the annual checks to which they are subjected, LOTO® balls are very special. And for good reason: same weight, same size, same material… They are all identical” the company stated.
“LOTO® balls are made from solid rubber, in a company in the North of France that closely reviews every detail in order to obtain perfectly similar balls. ‘A LOTO® ball is 5 centimeters in diameter for 26 grams!’, Reveals Julien Challet, responsible for the operations of printing, distribution and promulgation of FDJ games. Not 1 gram more, not 1 gram less” they continued.
