5. Bad Piggies
Bad Piggies ($1) was the first real spinoff from the Angry Birds formula, and it’s still the best by a wide margin. It’s all a role reversal: Instead of controlling the birds, you take command of the supposedly stupid pigs, building intelligent contraptions to guide them to a goal. Even more so than the source series, Bad Piggies is a puzzle experience, and it requires a lot of trial and error tinkering to get right.
You’ll construct karts, helicopters, and other makeshift vehicles using crates, propellers, balloons, and various tools, and the grid-like building structure makes it simple to build—yet producing a proper ride to tackle the tougher stages isn’t easy. It makes you wish the series opted for more of these brainier entries, rather than brasher, forgettable fare.
