I have a good app called 'Blocked' - its one of those puzzlers where you have to move the blocks in a grid to be able to remove a 'key' block. There are versions based in a car park where you need to shift the cars around to remove a target car. I just wondered if there's a 'best in class' of this kind of game? Any recommendations? I like Blocked but think there may be a better variant on the store? Cheers, Jamie.
