The Shortest Distance Between Two Points...Router Aqua is rated at 4.9 stars in Google Play and 3.1 stars in the Amazon Appstore.
Router Aqua is a brain game that requires connecting matching color dots in the shortest possible distance while avoiding overlaps. Explore multiple routes through seven chapters, each more complex than the last.
... Isn't Always a Straight Line
Chapter One introduces you to the basic gameplay and is well-suited for players of all ages. Chapter Two requires a bit of intellectual dexterity. For Chapter Three, you need to earn at least 130 points from the previous chapters to continue the game. Finish each stage with a perfect score to earn a Star Point. When you earn five or more Star Points, use them to get hints on more difficult levels.
Keep in mind that you need to plan ahead before you connect the first line, or the rest of the lines will tangle--and won't connect. Each stage (or level) offers up to five stars, earning you a Star Point for a perfect score. Capture the Star Point by joining all dots in the stage using the shortest possible lines.
Part circuit board, part connect-the-dots, Router Aqua's simple yet beautifully designed, glowing graphics pull you from level to level as you work through incrementally challenging puzzle boards. Every chapter contains lots of levels, and as you master the game, you may find yourself wandering back along familiar paths to replay, working toward even better scores and making your mark on the global leaderboard.
However, many of the negative ratings are around the "paid game with in-app purchases" theme, which is much more hated in the Amazon Appstore than in Google Play. It is true that it does make less sense to have a paid game with in-app purchases, as well, but the game appears to be playable without buying anything in-app.
Router Aqua is also available in the iOS App Store. The iOS version is $1.99 in the App store, but does not have enough ratings for Apple to display. It also includes in-app purchases.
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.
