Cookie Master

Each festival, we need cookies, massive of cookies. Especially this Christmas!

Put more than three cookies together will make a new high level cookie, do this until make the cookies that the cookie box needed.

But it is not an easy work, due to different cookie boxes have different internal structures and they also will provide vastly different cookies as material, even the naughty snowman and giftbox will try to stop your plan.

Never mind! aggregate four cookies as a bomb to destroy them, and collect the rare star cookie and props -- they are probably the last straw to clutch at when you stuck.

Come on! Cookie Master! Accept the challenge from these cookie boxes!
