Facebook is the home of embarrassing photos, people you wouldn't talk to anymore in real life and privacy statements that are discussed the world over every time they're updated.
It's also home to hundreds of games that millions of players around the world get stuck into on a daily basis. Here's our pick of nine of the most addictive Facebook games.
One of the most recognisable games in the world is also one you can play on Facebook for free, and it's brilliant fun.
Flinging fowl at evil - or perhaps misunderstood - pigs sounds daft, and it is. Oh, it's also totally addictive and the sort of thing you'll lose hours to.
Pool Live Tour
Pool is always a good way to spend some time, to kill an hour here or there. So why not do it in this excellent video game version of the pub pastime?
Best of all, you can play Pool Live Tour against your friends or others online. And as there are millions of players, you'll never be short of competition.
Jurassic Park Builder
Build your own Jurassic Park. That's all we need to say, really. Just don't hire Dennis Nedry - he's not the most reliable of employees.
Building up your own park to house the dinos is captivating and addictive, and Ian Malcolm's on it, so it's great.
One of the most popular and influential puzzle games ever made, Bejeweled hit its peak with the Blitz edition.
Tens of millions of people play the gem-matching game, and that's for a very good reason: it's brilliant.
It's got some (cartoony) adult content, but Criminal Case is great for appropriate players. A hidden item/adventure game, Criminal Case tasks players with solving a series of cases.
Ignore the fact it's set in a town called Grimsborough and just go with it - Criminal Case is captivating when it wants to be, and it often wants to be.
Words With Friends
Would we get into trouble if we called this Scrabble by another name? Yes? Oh, we won't do that then, even if that's what Words With Friends is.
It's the classic competitive word game, with players trying to out-dictionary one another in their race to the top of 'I should have been on Countdown' Hill. Scrabble is brilliant, so it's unsurprising that Words With Friends is too.
Farm Heroes Saga
There's a certain other 'Saga' game below, if you want to skip ahead to the most obvious choice in any Facebook game list ever. But those who want something a tiny bit different could do a lot worse than Farm Heroes Saga.
It's a match-three puzzle game with a farming theme, and it's as captivating as you'd expect from a King game. That is to say: you'll get addicted, given half a chance.
Top Eleven: Be a Football Manager
11 million players is a fair few, truth be told, and Top Eleven has more than that playing the game right now.
It's a simple, straightforward and fun football management game and it offers a great way to wile away the odd 10 minutes here and there. And those 'odd 10 minutes' will add up soon enough - you will get addicted.
Candy Crush Saga
We started with the obvious Angry Birds, we end with the just-as-obvious Candy Crush. If you haven't played it yet, you're missing out.
The object of the game is to match up the same type of sweet. That doesn’t sound very compulsive, does it? But trust us, once Candy Crush gets its sweet claws into you, it doesn’t let go.
