There are a lot of puzzle games in the App Store, and one of the best selling games was a puzzler called Blocked. Blocked made it to the top of the App Store for a while, and as usual it spawned a lot of variants and copies. Blocked is about getting a block out of a hole in a wall, but it is blocked by other blocks. You have to drag the blocks in order to get the target block out. A lot of variants using other obstacles such as cars have been invading the App Store using the same formula, and controls as Blocked. Now, finally a title that takes the formula to the next level has arrived: Wriggle.
