SIxeso - Memory/concentration/pairs game

Wikipedia: Game concentration, also known as Match Match, Memory, Pelmanism, Shinkei-suijaku, Pexeso or simply Pairs, is a card game in which all of the cards are laid face down on a surface and two cards are flipped face up over each turn. The object of the game is to turn over pairs of matching cards.

My colleague Dominik Pražák created a SIxeso. It is based on derived units with special names and symbols, as defined in SI Brochure. One has to find pairs of unit symbol and its expression in terms of base units.

I have to say this game is challenging even for professional metrologist, even for ones acting in the field of electrical measurements.
