Mega Brain - The numbers play

Every game you will be provided with a table of the boxes. Each box will contain a number ranging from one to four .

You will also have a second table where you have to rebuild the first table following the rules that follow .
Each empty box when clicked will take the value of " 1 " , if the boxes bordering clicked to that already contain a number, this number will be incremented by " 1 " .
Of course you can just click the empty boxes and not those full ....

What is left to say .... Have fun ...
