Doesn't time fly when you're clashing with clans?

It's been a whole year since Supercell released its free-to-play strategy world builder Clash of Clans.

To celebrate, the Finnish developer has given you a present. A digital present, mind.

For one entire week, you can boost a resource collector with just one gem. Or you can boost four of your resources collectors with just four gems. You get the idea.

We gave Clash of Clans a Gold Award when we reviewed it last year, and stated that "those looking for an opportunity to build a world, while destroying someone else's, will find Clash of Clans a very appealing package with surprisingly deep layers of strategy to dig through."

If Supercell's birthday promotion is enough to entice you into giving this social strategy scrapper a try, you can grab it from the App Store for free right now.
