The official Star Trek Trexels twitter account just confirmed the game is coming to Android this year: https://twitter.com/StarTrekTrexels/status/444191836203008000 And if you've never heard of Trexels, here is the official site: http://yesgno.me/star-trek-trexels/
I paid $2.99 for the iOS version. In addition, there are massive in-app purchases you need to make (which I didn't) for the game to be remotely playable.
