Freekick 2 is a free, ad-supported soccer game that lets you take repeated direct free kicks on a goal.
Freekick 2 looks great, with a photorealistic field and cartoonish players, and it has a fun, easy-to-learn interface that lets you adjust the speed and direction of your shot, including the ability to put a little bend on the ball. You tap arrows to rotate your point of view left and right, and you swipe your finger up an arrow to determine the force and spin of your kick. As you score, the number of defenders rotates between one, two, and three. (The game also offers a "Challenge mode" as an in-app purchase, which adds the ability to somehow invoke a T. rex, UFO, and "crazy soldier.")
Unfortunately, with a little bit of experimentation, you can score almost every single time with exactly the same one or two shots (adjusted for the position of the defenders), which makes the game boring very quickly. Another, more minor problem is that the app's rotating banner ads completely obscure your score while you're playing.
Freekick 2 has a lot of potential for a free kick game, but it needs some more testing and work--perhaps by improving the goalie AI, or making the defenders more dynamic--to make it a worthwhile download.
