10 Shades of Grey for Android
In this game you must reach the darkest shade of grey by swiping vertically or horizontally. As you combine the same shades of grey you will be left with darker shades. Reach the darkest to finish the game.
It sounds easy but any 2048 veteran will tell you, it really isn't. Reaching that darkest shade of grey will be a challenge and if you are ready to take it then play!
