Today for free in the Amazon Appstore you can get Siege Hero. Which is a game a bit like Angry Birds where you throw rocks at a flimsy wooden construction and try and kill everyone on screen.
Here is the developers take on what the game is about:
It’s amazingly realistic FREE HD castle crushing fun! Description
“Physics puzzle games have always had a safe home with casual gamers, and Siege Hero is easily one of the best!” -JayisGames.com
“As things stand, Siege Hero already represents a genuinely genre-expanding twist on projectile-based play” -PocketGamer (Silver Award – Score 8)
Hero’s Wanted!! Use strategy and precise aim to tumble down the Fortress’s and Free the Oppressed.
Tear down the 200 HD castles across three Ages. If you’re good enough to earn Gold on each castle you’ll unlock the extra looting levels in the Treasure Map. Over 10-hours of gameplay.

Some people have said that as the same game is free on the Play Store what is the point, well the Amazon Appstore version is the paid version which is normally only available after an in app purchase.
Getting the UK Amazon Appstore is a bit of faff. I’d head over to this link here to download it. Also if you have the US version installed it won’t work.
