What Is GN Math?

By the GN Math team · Updated

GN Math is a free website full of browser games you can play without downloading anything. You pick a game, press play, and it starts right on the page. There are 171 games right now, split into 9 categories, and none of them asks for an account or an email address.

The site is aimed at the moments when you have a few minutes and a browser, such as study hall, a lunch break, or waiting for a class to start. That is why the games are small, start quickly, and work well on school laptops and Chromebooks.

Where the name comes from

“GN Math” became a shorthand among students for a site where math-flavored and casual games live side by side. You will still find plenty of number play here, including a cage-sum logic grid, a factor game, a speed arithmetic quiz, sudoku and a tile-merging puzzle. Over time, the collection grew well beyond math. Today it includes chess and other board games, arcade shooters, sports, racing and strategy.

Because people search for it in different ways, you will also see it written as gn-math, gnmath, gn.math or gn maths. This site uses the plain spelling, GN Math.

How GN Math is different

Many game sites pull games in from big outside portals, with layers of ads and redirects. Here, every game is an open-source HTML5 project, and its files sit on this same site. That has a few practical effects:

  • Faster loading. A game page loads one small game, not a chain of third-party scripts.
  • No surprise redirects. Pressing play never takes you to another website.
  • Clear credits. Each game page names the original creator, links to the source code, and lists the license.
  • Fewer moving parts. There are no logins, chats or online lobbies, so there is less to go wrong on a school network.

What you can play

The biggest shelf is puzzle games, with logic grids, sliding tiles, pipe puzzles and color sorting.Board and card games cover chess, checkers, backgammon, mancala and several kinds of solitaire, plus some very old games such as Senet. For quick reflex play, the arcade andaction sections have space shooters, brick games and survival waves.

There is even a small group of games that teach practical skills. These include writing CSS selectors, arranging layouts with flexbox and grid, typing git commands, and snapping together code blocks. They are handy when you want something that still counts as learning.
