Whether you play games all the time or just want something to fill a few quiet moments here and there during the day, passing the time doesn't need to be expensive.
Yes, you need to break out your wallet if you want the latest big AAA shooter, but the free route is becoming increasingly interesting. Many older games are now opening out in search of a wider audience, and more and more companies are finding ways to profit from free releases.
For indie developers, it's the perfect way to make a name for themselves, either just for the glory or to build an audience for future games.
US company 2D Boy, for example, launched onto the scene with Tower of Goo, a game that involves building a tall tower out of bouncy balls of stretchy slime. This free download morphed into the amazing full title World of Goo, which took the net by storm.
We've gathered together 20 of the best free games around, covering releases new and old from every genre. With so much choice, you're guaranteed to find at least one you like. Give them a go – there's nothing to lose.
