In YOMEN, each player is given a set of three colored blocks with which to build a structure behind a screen. Each player is also given a set of "detective" blocks that match the colors of their opponent's pieces. On a turn, a player asks their opponent about what is visible from a specific direction, and the opponent answers, such as "Black is on the bottom row, green in the middle, and nothing on the top". If a player has asked about a side view, then the asker also provides the answer for their structure. If a player has asked about the view from above, then only the person being asked the question answers. The players take turns alternately, and the first to correctly guess the opponent's structure and orientation wins!
