It looks like a trivial game, and when a game of tic-tac-toe ends a few seconds later with a satisfying X and O filling up every available space, who can argue with that? For decades, researchers and teachers have actually been analyzing the impact of tic-tac-toe on the developing brains of children. The results are surprisingly remarkable.

Here are 5 true benefits of playing tic-tac-toe as a kid:

1. It encourages cognitive skills early on

Every move requires the child to look at the board and then think about where to put their next marker. Where will it help me get three in a row? Where does my opponent pose the most immediate threat?

These might seem like easy choices to us, but these actions are powerful stepping stones for kids in logical reasoning. Teachers at PlaygroundEquipment.com are advocates for this sort of "logico-mathematical thinking" in which a child learns to look for patterns and anticipate future scenarios; the foundation of science and math classes later on. In a study conducted in 1993 by Carnegie Mellon University, they made a five-year-old girl play a program that only knew how to win and lose. Each time she was determined to achieve victory, the computer won the game due to her overlooking the chance to defend. The exact opposite happened every time she was only trying to prevent losing the game. This experiment proved just how complicated it can be for the young mind to balance two different priorities when it comes to a game like tic-tac-toe.

2. It introduces strategic reasoning

Tic-tac-toe is entirely about strategy – there's no luck involved. With absolutely no chance components to interfere, the win or loss depends solely on the player's moves.

Children have a great chance to practice cause-and-effect reasoning in this game. If I move here, will my opponent know exactly what to do next? Am I trying to set up an inevitable win at some point? If they move there, then I should put mine here. All of these questions are key strategic thinking points. Since the game is compact enough that you don't have to strain your brain, it is the perfect first game for any child to play as a practice for games that require much more thought, like chess or draughts.

3. It fosters social skills and sportsmanship

Most tic-tac-toe games are played in real time with a partner. Because of this, children can learn crucial skills of turn-taking, patience, and graceful competition.

How to win without being too cocky and how to handle defeat without falling into a tantrum are two highly valuable lifelong skills. Tic-tac-toe provides a child the opportunity to practice over and over again in a context with minimal pressure and immediate results; you can be right back at square one (literally!) just two minutes later! An article from New Directions for Child and Adolescent Development, published in 2026, revealed that adolescents who played tic-tac-toe before interviews experienced 80% less anxiety and opened up more in their interviews due to the game's familiarity and low-stakes nature, transferring that relaxed social demeanor to their normal play time.

4. It encourages the child's understanding that a tie can be a success

Very few children's games end in a draw; and if the game ends in a tie, they often think that they "lost". However, tic-tac-toe ends in a draw, and this can be a really important learning opportunity for a child to realize that the goal isn't always to win, and that there are different definitions of success. The focus shifts from being better than the person they are playing to just simply not making a mistake, which is often what we want them to think like in real life. Just as the experiment from Carnegie Mellon had proven, it took the little girl many tries at the game to truly get the concept of working towards both offense and defense; this achievement can be really valuable as they do not just get the information, they figure it out themselves!

5. There is nothing required for the game other than what you and your partner have available

A pen, a pencil, paper, a stick, or even your finger in the sand will do! Tic-tac-toe was originally drawn into paved surfaces by the ancient Romans 2000 years ago; all you need is that surface and the other person playing. This ease is why the game has been able to transcend the ages and remains one of the first games a child learns how to play. This lack of any need for technology or supplies removes any barrier that can be hindering the child's chances to play with their friends and family.

If You're Planning to Play Tic-Tac-Toe with a Child

When playing a game of tic-tac-toe with children, make sure you give them plenty of time to answer your questions and even encourage them to explain why they are playing where they are. Speech therapy programs like the one in Adelaide, Australia have seen children develop cognitive skills while having the most fun they have had during the process of trying to predict the opponent's moves and then verbalizing the game plan.
