The game is about putting two numbers together in the same row or column.
First select a number that will be merged with the next number that is selected. It must be the same number in both boxes.
The new number ends up in the box for the last box selected. The new value in the box will be one higher than the number of the selected boxes.
When two numbers are merged, you get a new number, sometimes two numbers, somewhere on the board.
The value of the numbers you add up is given as score.
