love this type og puzzles.
it's based on nintendo ds' "pic pic" "magipic" and recently nintendo 3ds' "phil fill-a-pix". conceptis also introduced it to its line up on ios and android.
will surely download your version too on google play. wish your games are available on ios too.
edit: i am playing it on google play right now and it works well on my samsung tab s2.
HOWEVER i have one complaint: why don't numbers grey out or fade away when they meet their condition? it makes the puzzle so much easier to navigate. for example in the nintendo ds game "pic pic", the numbers turned from black to green when you colored their matched tile numbers or red when you added one more tile than them.
can you please look into it?
