Your mission in Angry Birds is to destroy all the green pigs by catapulting birds at them. This wouldn't be too difficult, except for the fact the hogs are holed up inside fortified castles which you need to smash into in order to enter. As the levels progress, these fortresses become ever more impenetrable, so Angry Birds requires a bit of lateral thinking as well as a steady aim.

Playing the game
To fire one of the angry birds you simply pull back on the catapult, adjust the trajectory, then release your finger. You can shoot four birds per turn, and if you don't destroy every pig then you'll have to start the level again. This free version of Angry Birds includes 15 playable levels. It gets very difficult, very quickly so even this trial version should last you a while.
As well as being great fun to play, Angry Birds looks the part too. Graphics are colorful and fun, and the bird noises and sound effects are hilarious. Playing the game on high resolution screen such as that of the HTC Desire is a real dream.
