Simple Matching game - Need to work with Chromecast

Hi,  I need a simple android game to work with on a tablet and be displayed on a Flat Screen TV using Chromecast.  The game is a matching game that works like this:  you have buttons (something like a keyboard) that are letters and numbers.  One letter/number will light up and user needs to press that letter/number. Then the same letter/number will light up again and and additional letter/number, user needs to press the same sequence.  So it goes with 3, 4, 5 and up to 10 straight letters/numbers.  If the user gets the 10 stragith letter/numbers in the same order, then the app should display some text saying he/she is a winner.  This should be an app for Android Tablets but should work with Chromecast. The app should be displayed simultaneously on the tablet as on the Flat Screen TV.  Please let me know any questions you might have.
