LOUISVILLE SLUGGER HOMERUN CHALLENGE is a free app, inspired by Major League Baseball's "Home Run Derby" event played prior to the All-Star Game. Controlling your batter is simple: swipe up on the screen for the hitter to swing after the ball has been pitched. If your timing is good, you'll hear the crack of the bat and watch as your ball sails out of the field; you'll also see the direction, power of the hit, and perhaps some feedback, such as a hit being too early or late. Throughout the game you'll see achievements you've unlocked -– such as five home runs in a row -– and at the end of each game you'll see your best score, longest drive, number of home runs, and longest streak.
The main drawback for this app is that it's not clear what's required to move onto the next location. The instructions say you need 1,500 TPX points to unlock the next stadium, which is different from your regular score. The game never explains what a TPX score is (located in the top-right of the screen), why it's different from your regular score, and what you need to do to raise it. On a related note, along with the Classic and Practice modes, there is also a Target mode that can be unlocked with 35,000 TPX points or by paying 99 cents as an in-app purchase. Other in-app purchases, which range from 99 cents to $1.99, might be for extra bats, landmark locations, and the ability to acquire the authentic Louisville Slugger bats of superstars. The game is fun, but flawed.
