Logic Puzzle Wooden DOUBLE TANGRAM

Board game of logic and imagination for 2 players or teams, where each has a 7-piece tangram set in front of him. Players choose a card with a shape and try to put it together. The player who gets the shape right the fastest wins.
A tangram (international: tangram, Chinese: 七巧板, pinyin: qīqiǎobǎn, meaning seven flat tiles) is a puzzle consisting of 7 flat shapes, called tan (tan, seven), which are joined to form shapes. The player's goal is to form some specific shape (of which only an outline or silhouette is given) using all 7 pieces, without overlapping each other. The tangram is rumored to have been invented in China during the Song Dynasty (960-1279 AD) and then brought to Europe via merchant ships in the early 19th century. It became very popular in Europe for some time and later again during the First World War. It is one of the most popular puzzles in the world. A Chinese psychologist has described the tangram as "the world's shortest psychological test", although anyone who engages in it does so for entertainment rather than psychological analysis.
