Word Rush is not available in Google Play; it is normally priced at $0.99 at the Amazon Appstore. As we've noted before, there are sometimes differences in pricing and availability between the two marketplaces.
Word Rush is described as follows:
“One of the coolest things you can do with an iPad” - KotakuWord Rush has a 2.7-star rating in the Amazon Appstore.
“If I were to recommend one game for kids on one of those “this is the stuff you should buy your kids” lists? This would be it.” - Fast Company
“The possibilities with this app are virtually endless.” - 148 Apps
“Its open-ended nature and resemblance to popular educational toys will appeal to parents who are uneasy about kids ceaseless desire for screen time.” - PadGadget
Become an inventor as you design unique creations and then set them in motion. You’ll never know what to expect as you watch your creations bounce, roll, tilt or even accelerate on the screen. Let your creations come to life as you play with different joints, forces, motors, teleporters, and inputs then watch what happens next. From the simplest bouncing ball to an elaborate pinball machine, the possibilities for tinkering are endless on Creatorverse.
Issues with the app appear to be permissions and poor gameplay.
There is also a version of the app in the iOS App Store. There it is priced at $0.99, but has insufficient ratings to display.
We'd like to see free versions of say, Office-compatible software or useful utilities such as CalenGoo instead of niche apps or endless games (we just assume every day that it's going to be a game; it's gotten that bad).
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.
Apple has already lost a portion of that lawsuit, which said Amazon.com had participated in "false advertising."
