I Built a Tic-Tac-Toe Web App — Here’s Why It Was Worth It
Yes, I built a Tic-Tac-Toe web app. I know what you’re thinking — of all the things to build, why that? It’s one of the oldest, simplest games in existence. But that’s exactly the point. Finishing something small and doing it properly teaches more than you’d expect. You can play it right here on the blog via the apps menu — no download, no sign-up, just open and play.
Why Build a Tic-Tac-Toe Web App?
When you work in tech, it’s easy to always chase complexity — the bigger the project, the more impressive it sounds. Building something small and finishing it properly is more valuable than starting something ambitious and never completing it, though. A Tic-Tac-Toe web app is the perfect scope for a focused personal project: clear rules, defined logic, a real end state, and something anyone can immediately understand and use.
Adding more interactive content to this blog was also a goal. Calculators, a Wordle clone, a weather app, and some crypto tools are already here — but something purely fun, with zero barrier to entry, felt like it was missing. You don’t need to know anything about finance or health metrics to play Tic-Tac-Toe. Just click and play.
What I Built and How It Works
The Tic-Tac-Toe web app runs entirely in the browser — no server calls, no backend, no dependencies. Built with plain HTML, CSS, and JavaScript, it is embedded directly into the page. Two players take turns placing their marks on a 3×3 grid, and the game automatically detects wins, draws, and invalid moves. A single click resets everything cleanly for a new round.
The design is intentionally minimal. Flashy animations and unnecessary complexity would only get in the way — the focus is entirely on smooth, responsive gameplay whether you’re on desktop or mobile.
What Building It Actually Taught Me
Even a simple Tic-Tac-Toe web app involves more decisions than you’d expect. How do you store the game state? How do you check for a winner efficiently? Handling edge cases — like a player clicking an already-occupied square, or the game ending in a draw — each of these is a small but real problem to solve cleanly.
The win detection logic was a particularly nice exercise. Eight possible winning combinations exist on a 3×3 grid — three rows, three columns, and two diagonals. Writing that check in a readable way without hardcoding eight if-statements is actually a fun little puzzle. It pushed me to think about how to represent the board state efficiently and iterate over it in a way that scales.
As someone who spends most of my professional life in RPA and automation, dropping back to first-principles JavaScript logic is a good mental workout. Sharp fundamentals matter, even when your day job is higher-level.
Why I Keep Building Small Apps for This Blog
The Tic-Tac-Toe web app is part of a broader habit — shipping small, working tools that people can actually use. Alongside this game you’ll find a compound interest calculator, a net salary calculator, a BMI tracker, a Wordle clone, a weather app, a crypto chart analyser, and a few other things in alpha.
None of these are meant to replace professional tools. Personal curiosity, wanting to practise a specific skill, or simply finding something fun to build — those are the real reasons behind each one. A blog becomes more useful when it has things to interact with, not just articles to read.
Go Play It
Give the Tic-Tac-Toe web app a try by heading to the Apps section in the menu or clicking directly to the Tic-Tac-Toe page. Challenge a friend sitting next to you, or play both sides and see how long it takes to force a draw. Simple, fun, and always ready — sometimes that’s all you need.
