The game is pretty simple- there is a grid that consists of sixteen tiles. You begin with two tiles that are marked with either the number 2 or 4. With each move, you have to move the tiles either left or right, down or up to match the numbers in order to eliminate them. So when you swipe a number 2 tile with another number 2 tile, you cancel them both and change it into a number 4. Each matched tile gets multiplied and adds a new tile to the board. When there are not more matches for the tiles, combinations and space on the board, you have officially lost the game. The best way to understand the game is to play it on your own, and the best part is that there is no score board or time challenges, so you can manage the whole game within a day.
