Amazon Appstore's Free App of the Day, 6/13/2012: Voltage Premium has promised to make a paid app free every day in the Amazon Appstore, and today's app is Voltage Premium.

Voltage Premium is only available as a free, ad-supported app in Google Play, and is normally priced at $0.99 in the Amazon Appstore. As we've noted before, there are sometimes differences in pricing and availability between the two marketplaces.

Voltage Premium is described as follows:
Toying around with powerful electric circuits just became casual gameplay. Voltage Premium is a challenging puzzle game that requires you to connect the blue electrical circuit with the red electrical circuit.

Getting Wired

The red current comes from the tube running up the left side of the screen, and the blue current comes from the right. Each tube contains multiple outlets. Connect to an outlet with a provided puzzle piece and slowly work your way across the screen until you connect the two currents.

Similar to Tetris-style gameplay, you're given one puzzle piece at a time, but they're all different. Some pieces rotate, while others do not. Some pieces can slide across the top of your screen allowing you to drop them anywhere, while others sit stagnant. This is determined by the color of the piece. You'll always know the next available piece which is displayed in the corner. Play smart; you're only one step ahead.


Earn bonus pieces for more turns, to swap pieces, or to activate a bomb. Most bonuses are earned after leveling up and appear as a colored button at the top of your screen. Colored buttons are good. We like to push colored buttons.

Build the high-voltage circuit in two game modes: Timed or Unlimited. Compete with other players through OpenFeint scoring system.

The diesel-punk themed graphics and high voltage snaps, sizzles, and zaps are ironically paired with an easy-listening, instrumental ensemble. It's classy and dangerous! Now, would someone please hold my overcoat while I quickly fuse some dangerously high-voltage fuses?
Voltage Premium (free, ad-supported as Voltage) is rated at 4.6 stars in Google Play, and is rated at 2.9 stars in the Amazon Appstore.

It's not unusual for an app in the Amazon Appstore to be paid while it only appears as free and ad-supported in Google Play. Generally the developer will cite issues with restrictions in Google Play (but not detail them).

This is, however, the latest in a string of such apps in the Amazon Appstore.

It's hard to understand the big difference in ratings. Google Play has 228 ratings, so that's a solid average. The Amazon Appstore rating is affected greatly by OpenFeint hatred, but also because of such issues as lack of instructions, poor controls, and more.

Those who are considering "buying" a Free Amazon Appstore app might want to consider what it means to developers. opened up the Appstore despite a lawsuit by Apple, which has previously trademarked the term "App Store." Microsoft has filed an appeal against that trademark, saying the term is too generic. has responded to the lawsuit in the same manner.
