A browser game is a game that runs inside your web browser. That means Chrome, Safari, Firefox or Edge. There is no download and no install. You do not need an account. You click a game, and it starts.
If you have not played one since Flash went away, this guide will catch you up. It covers what browser games are today, how they work, and how to find good ones.
A short history
Browser games were a huge part of the internet in the 2000s. Sites like Newgrounds and Miniclip hosted thousands of Flash games. Many game developers started there.
Adobe ended Flash in December 2020. For a while it looked like browser gaming might die with it. Then HTML5, WebGL and JavaScript grew strong enough to replace Flash. Modern browser games are safer than Flash games were, and they work on phones too.
Almost everything you play today on a site like TwozyGames is HTML5. Try 
Drunken Fighters or 
Formula Racing Games Car Game to see how far it has come.
Why browser games beat app stores for quick play
No install. A browser game takes no storage on your phone.
No account. You do not sign up to play. Progress is usually saved in your browser.
A fast start. You click and the game loads in seconds. There is no store page and no update to wait for.
Safe. A browser game runs inside the browser's sandbox. It cannot read your files. It cannot install itself. It stops when you close the tab.
Any device. The same address works on a laptop, a tablet and often a phone. Some games are built for just one of them.

Two kinds of game site
Most browser game sites are portals. A portal does not make games. It shows games from a distribution network, inside a frame on its own page. That is normal, and it is how most of the web's free games reach you.
A smaller number of sites are studios. They build their own games. TwozyGames does both. We make our own two-player games, and we also pick games from a partner catalogue called GameDistribution. You can tell them apart on our site. Our own games have their own section, and they carry no ads inside the game.
What to look for in a browser game site
It picks, it does not dump. A good site leaves weak games out. It sorts the rest into groups you can use, like two-player or phone-friendly. A site with five thousand games and no advice is just a pile.
It says where the games come from. Showing partner games is fine. Pretending they are your own is not. Look for a plain statement about sources.
Games start in place. A good site loads the game on the same page. Be careful with sites that open new tabs or make you click start three times.
It has a real privacy page. Free game sites usually use analytics and ads. A good site names the companies involved and tells you how to opt out. A single vague paragraph is a warning sign.
Where to play
You are already in a good place to start. TwozyGames focuses on games for two people on one device. If that is what you want, begin with our originals or the same-keyboard guide.
