This new game shows things from the pigs’ point of view. In a risky move, the makers have abandoned the “flick and hit” move that Salman Rushdie said he has “mastered” for a more complicated approach where users build their own flying, rolling or spinning device to help the porkers get revenge on the fowl. Unlike birds, pigs can’t fly, so they need equipment. There are 60 levels to work through and, like Birds, it costs 69p. There have been some doubts about whether Rovio can match the success of Angry Birds, which has its own theme park, and the gaming community have been mumbling about Bad Piggies being the equivalent of a difficult second album. Tetris was a hit in 1984 but Super Tetris didn’t catch on, Pac-Man had no sequel and Zynga’s Farmville fell from 83 million monthly users in 2010 to 18.7 million today.
