Amazon.com has promised to make a paid app free every day in the Amazon Appstore, and today's app is Spinballs.
Spinballs is priced at $2.81 in the Android Market. Meanwhile, it is normally priced at $2.49 in the Amazon Appstore. As we noted previously, prices sometimes differ between the two stores.
Spinballs is described as follows:
Spinballs combines match-three gameplay with logic-based strategy. The game consists of seven discs containing six colored balls apiece, like a ball bearing. The objective is to link three or more balls of the same color by spinning the discs. Discs can be turned both clockwise and counter-clockwise, depending on which side of the disc you tap.Spinballs has a 4.6-star rating in the Android Market and a 3.0-star rating in the Amazon Appstore.
Link as many as possible before the time runs out, as indicated by the bar along the top of the screen. The best links will charge your Helping Elements. Once you've got three or more linked, hit the execute button to eliminate the balls, and refill the spots with new colored balls.
Often, especially in the easier levels, balls will link with very little effort on your part, but to achieve highest scores, fill the Helping Elements that rest in each corner of the screen. This requires more effort, and is necessary to reach the higher levels.
Charge Your Elements
Helping Elements can be charged and triggered. Charge Helping Elements by linking colored balls that are directly in front of the Element. An arrow will appear indicating that this link is going to charge the Element. Hit the execute button, and watch the Element fill. The bigger the link, the more the Element is charged. Each Element has its own purpose: to clear the field, freeze time, sort all balls, or multiply the points earned. Once you fill an Element it will be illuminated; save it for when you need it. Trigger it with a tap.
As you progress through levels, you are given less time to create links. Utilize the four elements wisely and develop your own strategy to reach the higher levels.
Unlike many match-three games, this interface has a tough, industrial vibe, rather than jewels, cartoony fruits, or smiling animals. The discs resemble bearings and the sound effects sound more like something you'd hear in a mechanics garage--air tools and intense music.
At issue in the Amazon Appstore crashing issues, and the timer being too fast to allow any strategy to take place.
When there are this much of a difference in ratings between the two stores the question is usually: why? Generally it seems because the much larger number of reviews in the Android Market allow the "bad" reviews to not take as much effect. In this case, there are 36 reviews in the Appstore and 49 in the Android Market.
Those who are considering "buying" a Free Amazon Appstore app might want to consider what it means to developers.
Amazon.com 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. Amazon.com has responded to the lawsuit in the same manner.
