It's not on the Apple TV PlutoTV app (yet). However, it appears that either PlutoTV or Buzzr are "zooming" the 4:3 image to fill a 16:9 screen since it's on the WatchFree app. When Classic Concentration is on, the entire bottom row of the game board is missing. :-(
On the Buzzrplay.com livestream, it's not zoomed, and looks like it should.
