Today's MyAppFree title is addictive game Quarto

Today’s MyAppFree game is Quarto, an addictive game for 2 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:

• tall or short;
•  red or blue (or a different pair of colors, e.g. light- or dark-stained wood);
• square or circular;
• hollow-top or solid-top.

Players 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.
