A kids' game created by two Arlington moms has been named one of 20 finalists out of nearly 500 submissions in the Amazon Alexa Kid Skills Challenge. Alexa is the voice of Amazon’s hands-free, voice-controlled technology.

The app, The Queen's Mathematician, by Emily and Heather Calvin-Bottis, is a choose-your-own-adventure-style math game set in a quirky tree-house castle full of kid friendly humor, surprising choices and mischievous elves. The Queen's Mathematician is best for ages 6 through 8.

Creating the game was an all hands-on-deck collaboration, the creators' said in a Feb. 1 news release. Emily conceived of the concept, structured and coded the game. Heather did the writing. Their daughters tested multiple versions and contributed ideas.

"Our goal was to make a game that would make our own daughters love math even more than they already do," Heather said in the release. "It's awesome that being picked as a finalist means our game will reach more kids and help them find the fun in math too!"

The Alexa Kids Skills Challenge will conclude with winners expected to be announced Feb. 28. During February, Amazon will promote the finalists' skills and consider customer engagement, such as number of plays and ratings along with other factors to determine the winners.

The skills created for Alexa are free to enable and will continue to be available through Amazon on an ongoing basis after the contest.
