Pattern Factory Free

Pattern factory is a unique and challenging spacial-reasoning based puzzle game for Android tablets and phones. You start out the game as a new employee at a Pattern Factory, where you train to put quirky machines together on an assembly line, with the ultimate goal of having them work together to drill specific patterns into pieces of sheet metal. As you get more familiar with the game and complete more and more levels, the patterns you
are asked to drill and the number of machines you'll need to use become more and more complex.

Pattern Factory uses a unique blend of robust, time-tested development patterns, and creative out of the box solutions, to provide a new and exciting game experience:
1) Our "scale-up level design" ensures the most crisp graphics available are displayed on your Android device with minimal wasted space‐whether it be on a small phone or a large tablet, the graphics look great!
2) 25 painstakingly hand crafted levels add just the right touch to your puzzle solving experience. And then, once you unlock infinite mode, the game can literally generate levels for you forever! The fun never stops!
3) Unlike other mind-numbing mobile games, Pattern Factory actually helps to keep your mind sharp and active, while improving your spacial reasoning skills.
4) Our in-game hint system gives just the right amount of information to keep you moving forward if you get stuck, while still keeping levels challenging and rewarding.
5) Our 3d-rendered-as-2d graphics provide excellent graphics while also draining less battery than traditional 3d-only models.
