Tabletop Game: Tic Tac Toe
Tic-tac-toe, also called tick tack toe, or noughts and crosses/Xs and Os as it is known in the United Kingdom, Australia and New Zealand, is a pencil-and-paper game of unknown origin. Two players, X and O, take turns marking the spaces in a 3×3 grid. The X player usually goes first. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game. If the board fills up before anyone accomplishes this (which is very likely to happen between players with any experience), the game is a draw.The first video game, OXO, is pretty much this in video game form. It was the basis for Tic-Tac-Dough and The Hollywood Squares, as well as the Secret "X" game on The Price Is Right.
Video game adaptations:
- OXO (1952) for the EDSAC.
- Tim Soft's Tic-Tac-Toe (1994) for the Super NES.
- Stephen Ostermiller's Tic-Tac-Toe, one of many online versions. Includes a good strategy guide.
- Neave Interactive's Tic-Tac-Toe, online Flash with sound effects.
"Tic Tac Tropes":
- Casual Video Game
- Difficulty Levels: Some computer players never lose. To give the human a chance, some video games have difficulty levels.
- Ostermiller's Tic-Tac-Toe has four difficulty levels: Novice makes random moves, Intermediate blocks two-in-a-row, Experienced makes the best first moves, and Expert plays perfectly.
- Tim Soft's Tic-Tac-Toe has Easy, Normal and Hard. If you find the flaw, you can still win about 1 in 4 games against Hard.
- House Rules: Once the 3x3 grid gets too easy, players may trade up to a larger grid size. There's also a "3D" variant, played simultaneously on three separate grids (to simulate a cube), where getting three in a row in any direction (even across different grids) counts as a win.
- X typically goes first, but that's up to preference really.
- Match Three Game: Well, you need to get three X's or O's in a row, column or diagonal to win...
- Player Versus Player
- Separated by a Common Language: This game known as Tic-Tac-Toe in North America is known as Noughts and Crosses in the United Kingdom, Australia, and New Zealand.
- Strategy Game: One needs some strategy to avoid defeat in this game, as players are technically attacking and defending at the same time.
- Unwinnable by Design: If two skilled players play the game, they will inevitably force themselves into a draw. Many computer players, starting with OXO from 1952, can play a perfect game with no mistakes, so it is impossible to win against them.
- Video Game: Ur-Example. OXO, a 1952 version made for the computer, is believed to be the first computer/video game to use a digital graphics display.
Appearances in media:
- Tic-Tac-Dough: Game show. Answer questions, place X's and O's, win money.
- The Hollywood Squares: Game show with nine celebrities sitting in a giant grid.
- WarGames: One of the computer games on WOPR is "Tic-Tac-Toe". This game is as unwinnable as "Global Thermonuclear War".
- SMBC theater did a parody of this scene where the computer concludes that the lesson is to go first and control your opponent's options. Ironically, its justification uses terrible tic-tac-toe strategy.
- xkcd provides the Complete Map of Optimal Tic-Tac-Toe Moves. You will never lose a game again! Its Alt Text is a Shout-Out to WarGames."The only winning move is to play, perfectly, waiting for your opponent to make a mistake."
