Quarto!

Quarto is a board game for two players invented by Swiss mathematician Blaise Müller.It is played on a 4×4 board. There are 16 unique pieces, each of which is either: • Big or all • Light or dark • Square or circular • Hollow or solidPlayers take turns choosing a piece which the other player must then place on the board. A player wins by placing a piece on the board which forms a horizontal, vertical, or diagonal row of four pieces, all of which have a common attribute (all short, all circular, etc.).Quarto is distinctive in that there is only one set of common pieces, rather than a set for one player and a different set for the other. It is therefore an impartial game.Features: • Player vs Player • Player vs CPU • Three levels of difficulty
