Puzzle games are a huge thing on mobile devices, they’re easy, levels are simple to make and easy to add on to if the developers ever want to introduce some in-game purchases. In short, they are just the easy option for game developers to pursue, so it’s no surprise that the mobile gaming market is quite full of such games. It takes some serious individuality to be able to have a game rise above the rest and set itself apart.

Touch Arcade: Like it or not, you can’t ignore the physics puzzle category on iOS. With so many games to play that are just like it, why would anyone want to play Eager Beaver [ $0.99 ]? Because you’ve never played one with an incredibly excited beaver before, that’s why.
Most of the beavers in Eager Beaver are lethargic and just don’t care too much about building dams. In their place we have Edgar, a beaver who is so good at building dams that he has even created contraptions to do it for him. Edgar seems so excited about building dams that you probably won’t be able to help get a bit excited yourself.
AppSpy: Eager Beaver mixes up the tower-building concept by placing it underwater; while similar in many ways it proves to be entertaining despite the same-ish feel.

GDN: Edgar is an industrious beaver who’s created a crane to help his dam building abilities. But the items he finds to help dam up the rivers might not be exactly what you’d expect. The dam building pieces take on various shapes, sizes and materials, everything from oblong rocks to used up tin cans and more. Each reacts slightly differently to the rushing current that you need to dam up. On top of that there are switches, magnets, drain vents and even explosives that will help or hinder you on each level.
