Amazon Appstore's Free App of the Day, 4/17/2012: Mathris - A Math Game

Amazon.com has promised to make a paid app free every day in the Amazon Appstore, and today's app is Mathris - A Math Game.

Mathris - A Math Game is not available in ad-free form in Google Play, and it is normally priced at $1.99 in the Amazon Appstore. As we've noted before, there are sometimes differences in pricing between the two marketplaces.

Mathris - A Math Game is described as follows:
Do Sums. Have Fun.

Mathris - A Math Game is a Tetris-style game for kids to learn numbers and build their basic math skills while still having a blast. Players must scramble to solve arithmetic problems while correctly stacking the blocks.

Mathematical Blocks
The numbers fall like Tetris bricks, but you can only remove the bricks by matching a question and an answer (4+2 with 6), a question with a question that has the same result (4+2 with 3+3), or two of the same numbers (5 with 5).

Math Tetris features three game modes (addition, subtraction, and multiplication) and four themes (winter, spring, summer, and autumn).

More Options

Mathris features high scores, and is integrated with OpenFeint so you can compete with players around the world. Toggle sound effects and background music. Mathris also comes with a tutorial and option to customize the number space (1 to 10, 1 to 20, and 1 to 50). Just how fast are your arithmetic skills?
The free version of Mathris - A Math Game is rated at 3.8 stars in Google Play. It is rated at 2.3 stars in the Amazon Appstore.

There is also a paid and free version of a different version of an app called Mathis by a different developer in Google Play, so don't mix them up. This app is developed by divmobvn in Google Play (named divmob in Amazon Appstore) while Mathis and Mathris Free are developed by CLIQUEYOU.COM.

There are only 17 reviews in the Amazon Appstore, which means that negative reviews skew the overall rating mightily but most of the negatives were about bugs and poor performance.

FREE Shipping - Select Items only
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.
