Tic Tac Toe 2 Player: XO Game

Review by eFreeware

Some games ask for an evening, a tutorial and a spreadsheet of stats before you can enjoy them. Tic Tac Toe asks for almost nothing: two players, a grid, and a few seconds of thinking. That low barrier is exactly why the game has survived so long in notebooks and on chalkboards, and it is the gap that Tic Tac Toe 2 Player: XO Game fills on Android.

The app comes from Onetap Global, sits in the Puzzle category on Google Play, and is free to download. It has been installed more than 100 million times and holds a 4.3 average from 142,851 ratings, which suggests a lot of people have tried it and most have been content with what they got. It arrived in mid-2022 and was still being updated in 2026.

Noughts and crosses with a neon coat of paint

The premise is the one you already know. Two players take turns claiming empty squares on a grid, and whoever first lines up the required number of their own symbols in a horizontal, vertical or diagonal row wins. In the app the symbols are the familiar X and O, and the developer has dressed the whole thing in a glowing neon look rather than a plain paper grid.

What separates this version from the version you scribble on the back of an envelope is the range of board sizes. You can play on the standard 3x3 grid, or step up to 6x6, 9x9 or 11x11. That single change alters the game considerably: a 3x3 board is a puzzle you can solve in your head within a few moves, while the larger grids stretch the same basic idea over far more space and demand that you think further ahead.

The developer frames the app as a way to train your brain and plan a few steps in advance, and that description fits the bigger boards better than the small one. On 3x3, most adults reach a draw once they know the trick. On 11x11, the same rules produce something closer to a light strategy exercise, because there are simply more lines to watch and more ways to miss one.

How a round actually unfolds

A game begins with an empty grid and two sets of marks. Players alternate turns, each claiming one free space per turn, and the round ends when someone completes a row of the required length or the board fills without a winner. Nothing about that loop is complicated, and the app does not appear to complicate it either — the rules are the ones the game has always had.

You can play solo against the computer or against another person, so the app covers both the moments when you have an opponent nearby and the moments when you do not. The developer describes the multiplayer side as supporting both human and computer play, and also lists online two-player games so you can challenge friends who are not sitting next to you.

A round is short enough that people tend to reach for it in spare moments, and not needing a connection for the basic game keeps those moments usable. It is the sort of app that fits into a waiting room, a lunch break or the gap before something else starts, rather than something you schedule time for.

The board sizes give the same rules a different feel depending on how much time you have. A 3x3 round is over almost as soon as it starts, while a larger grid rewards a slower, more deliberate approach. Having both in one app means you can pick the size to match the time you actually have rather than the other way around.

What brings players back to the board

The strongest argument for keeping this installed is variety within a very simple rule set. Four board sizes, a computer opponent and human matches cover a surprising amount of ground for a game whose rules fit in one sentence. If you like the idea of noughts and crosses but find the standard grid too easy to exhaust, the larger boards are the part that will hold your attention.

The developer also leans on nostalgia, noting that adults may recall their old memories of the game. That is a fair pitch. Tic Tac Toe is one of the first games most people learn, and a version that looks sharp on a phone screen and offers a few new sizes is an easy thing to keep around for the odd quiet minute.

There is also a social angle. Because the app supports two players on the same device and online matches, it works as a shared activity rather than a solo habit. A parent and child can take turns on one phone, or two friends can play from wherever they happen to be. The game is rated for Everyone, which fits that use.

The developer's recent update note is short and simply invites players to enjoy the game, so there is no new mode or feature to weigh here. What you see described is what the app offers: the classic game, a neon presentation and a set of board sizes that scale the challenge up or down.

Free to play, with advertising

The app costs nothing to download and contains ads. There are no in-app purchases, so nothing inside the game asks you to spend money to keep playing, and there is no paid tier to weigh against the free one. The trade is straightforward: you get the game at no cost, and advertising is part of the package.

For a game built around short rounds, that arrangement is easy to understand. Anyone who dislikes advertising in mobile games should factor it in before installing. For everyone else, the cost of entry is a download and whatever attention the ads take.

The install numbers suggest the trade has been acceptable to a very large number of people. More than 100 million downloads and a 4.3 average from a large pool of ratings is not a guarantee of anything for you personally, but it does indicate that the app has held up for a broad audience over several years.

A quick game worth keeping on your phone

It takes the oldest grid game there is, adds a neon look and four board sizes, and lets you play against the computer, against someone beside you or against a friend online. The free, ad-supported model keeps it accessible, and the offline support makes it usable when a connection is not available.

I would point this at people who want a light puzzle they can pick up and put down in under a minute, and at anyone who wants a simple two-player game to share with a child or a friend. The larger grids give it more staying power than the 3x3 version alone would, and the option to play against the computer means you are never stuck waiting for a partner.

If you are looking for a deep strategy game or a long campaign, the rules here will not stretch that far, and that is fine — it is a pocket-sized version of a classic, priced accordingly. For what it sets out to be, it is an easy install to justify.
