Connect Four (also known as Four Up, Plot Four, Find Four, Captain's Mistress, Four in a Row, Drop Four, and Gravitrips in the Soviet Union) is a two-player connection board game, in which the players choose a color and then take turns dropping colored discs into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own discs. Connect Four is a solved game. The first player can always win by playing the right moves.
The game was first sold under the Connect Four trademark by Milton Bradley in February 1974.
Connect Four is a two-player game with perfect information for both sides. This term describes games where one player at a time plays, players have all the information about moves that have taken place and all moves that can take place, for a given game state. Connect Four also belongs to the classification of an adversarial, zero-sum game, since a player's advantage is an opponent's disadvantage.
One measure of complexity of the Connect Four game is the number of possible games board positions. For classic Connect Four played on 6 high, 7 wide grid, there are 4,531,985,219,092 positions for all game boards populated with 0 to 42 pieces.
The game was first solved by James Dow Allen (October 1, 1988), and independently by Victor Allis (October 16, 1988).

Shatranj (Arabic: شطرنج; Persian: شترنج; from Middle Persian chatrang چترنگ) is an old form of chess, as played in the Sasanian Empire. Its origins are in the Indian game of chaturaṅga. Modern chess gradually developed from this game, as it was introduced to the western world by contacts in Muslim Al-Andalus (modern Spain) and in Sicily in the 10th century.
The Persian word shatranj ultimately derives from Sanskrit (Sanskrit: चतुरङ्ग; caturaṅga) (catuḥ: "four"; anga: "arm"), referring to the game of the same name: Chaturanga. In Middle Persian the word appears as chatrang, with the 'u' lost due to syncope and the 'a' lost to apocope, such as in the title of the text Mâdayân î chatrang ("Book of Chess") from the 7th century AD. In Persian folk etymology, a Persian text refers to Shah Ardashir I, who ruled from 224–241, as a master of the game:
Three books written in Pahlavi, Kar-Namag i Ardashir i Pabagan, Khosrow and ridag, and Wizārišn ī čhatrang ("Treatise on Chess"), also known as the Chatrang Nama ("Book of Chess"), all mention chatrang. In Kār-nāmak it is said that Ardashīr "with the help of the gods became more victorious and experienced than all others in polo, horsemanship, chess, backgammon, and other arts," and in the small treatise on Khosrow and ridag, the latter declares that he is superior to his comrades in chess, backgammon, and hašt pāy. Bozorgmehr, the author of Wizārišn ī čhatrang, describes how the game of chess was sent as a test to Khosrow I (r. 531-79) by the "king of the Hindus Dēvsarm" with the envoy Takhtarītūs and how the test was answered by the vizier Bozorgmehr, who in his turn invented the game Backgammon as a test for the Hindus. These three Middle Persian sources do not give any certain indication of the date when chess was introduced into Persia. The mentions of chess in Kar-Namag i Ardashir i Pabagan and Khosrow and ridag are simply conventional and may easily represent late Sasanian or even post-Sasanian redactions. According to Touraj Daryaee, Kar-Namag i Ardashir i Pabagan is from 6th century. Wizārišn ī čhatrang was written in the 6th century.
