Apparatus for your Android phone involves Rube Goldberg devices. It's not quite Mouse Trap (and you thankfully don't have to keep track of all those tiny plastic pieces), but this puzzler's one-of-a-kind gameplay is truly exciting enough to promote to anyone who enjoys brain teaser apps.
To play, you have to drop a tiny marble into a blue crate by assembling several pieces and connecting them together in the correct order. Not every piece on the screen will be able to move, though, so you'll have to use your imagination to make the machine work.
Apparatus has a bunch of different tools that you can use, such as angled boards, chutes, see-saw-like planks and even motors that can make the marble travel across the screen.
The Rube Goldberg devices in Apparatus aren't quite as fun looking as you'd might hope. Thanks to TV and the movies, I always imagine colorful household items like wind-up swimming rubber ducks or hopping frogs, electric train sets or dominos used to create and perpetuate a chain reaction. The ones in this game are much more industrial looking, sadly.
I'm not especially great at puzzle games like this, but I still had a good time playing this one. I found the puzzles to be pretty tough, but, because I'm not the best at solving brain teasers, you'll have to be the judge of that.
My experience with the app overall, was quite pleasant and easy going, as I didn't have any difficulty understanding the rules of the game (there's a question mark icon that you can tap if you need any kind of tutorial), gameplay mechanics were accurate, and I didn't encounter any kind of hiccups while I had the app running.
That being said, I noticed a few consumer reviews in the Android Marketplace that reported issues with Apparatus. To be on the safe side, I'd recommend that you give the lite version of this game a try before upgrading to the full version.
