Dobble

Dobble is an observation and speed game invented in 1976 by French mathematician Jacques Cottereau, then rediscovered and turned into a commercial game in 2008 by Denis Blanchot. Based on a mathematical principle guaranteeing that any two cards always share exactly one matching symbol, it has been published by studio Zygomatic since 2009. The line has since branched into numerous licensed variants and editions, including Harry Potter, Disney and Super Mario.
