The popular Android game Apparatus has pushed an update today which adds 3 new games and fixes some bugs. Most notably, now clicking on the soft button 'back', it exits the app. Another bug fix, that you may not like patches the bug which unlocked all the levels in the previous update.
The game is available in two versions - Appartus Lite (the free version) and Apparatus paid version. The game is extremely engaging.
I use Apparatus for the best time killing game (I like it more than Angry Birds as it demands some mechanical skills). The goal of the game is to put a ball in the basket and in order to do so, you have to create bridges, use levers, create pulleys. In a nutshell, it is a fun game. I heavily recommend it to kids. Unlike Angry Birds it is not violent and is quite educational as well.
The game is very well supported on most phones and tablets including, Nexus One, Samsung Galaxy S, Samsung Galaxy S II (Please disable sound! This device crashes with sound on, we're working on a fix!), HTC Desire HD, HTC Desire, Samsung Galaxy Tab, ZTE Blade, ZTE Light, Acer A500 Tablet, Motorola Xoom.
