Eights!

The game starts by showing you a random set
of numbered tiles spread across its 4×4 board.
Your task is to merge/join the numbers.
5 can only match with a 3 to create an 8.
5 + 3 = 8
any number higher than 5 can match with itself
8 + 8 = 16
16 + 16 = 32
...
Match higher numbers to get your high score.

Game mechanics:
In order to merge the tiles you need to push
the tiles to the wall.
Simply swipe using one finger to any four directions
(up, down, left, and right) and all free tiles will
move along. Thus, you may be moving more than one
row or column at a time, and you may trigger
more than one merge in a single action.
After each move, the game will place a new tile in an
empty space left behind by the action.
It is important to remember that the space on the board
is limited, and the game ends when you can no longer move.
Hence, you must manage the free spaces.
I recommend planning for a move that will free two or more
spaces with a single action.
