From there, I wrote the first computer program of my own—a game of tic-tac-toe. Getting it to work forced me to think through for the first time the most basic elements of the game's rules.
[12] [17] To retrieve MENACE's choice of move, the opponent or operator located the matchbox that matched the current game state, or a rotation or mirror image of it. For example, at the start of a game, this would be the matchbox for an empty grid. The tray would be removed and lightly shaken so as to move the beads around. [4]
Bertie the Brain was a video game version of tic-tac-toe, built by Dr. Josef Kates for the 1950 Canadian National Exhibition. [1] Kates had previously worked at Rogers Majestic designing and building radar tubes during World War II, then after the war pursued graduate studies in the computing center at the University of Toronto while continuing to work at Rogers Majestic.

An animated pedagogical example showing the plain negamax algorithm (that is, without alpha–beta pruning). The person performing the game tree search is considered to be the one that has to move first from the current state of the game (player in this case) NegaMax operates on the same game trees as those used with the minimax search ...
This step is sometimes also called playout or rollout. A playout may be as simple as choosing uniform random moves until the game is decided (for example in chess, the game is won, lost, or drawn). Backpropagation: Use the result of the playout to update information in the nodes on the path from C to R. Step of Monte Carlo tree search.
OXO is a video game developed by A S Douglas in 1952 which simulates a game of noughts and crosses (tic-tac-toe). It was one of the first games developed in the early history of video games. Douglas programmed the game as part of a thesis on human-computer interaction at the University of Cambridge.
Hence, every winning-strategy of First in a strong-positional game is also a winning-strategy of Maker in the corresponding maker-breaker game. The opposite is not true. For example, in the maker-breaker variant of Tic-Tac-Toe, Maker has a winning strategy, but in its strong-positional (classic) variant, Second has a drawing strategy. [2]
