slingo final award

I still need unslingo and a few patterns so I have 9 of 12 awards BUT the final award says I have 11 more to go! Are there secret hidden awards?

No, there are no hidden awards, just the twelve shown. In order to get the last award, you have to get the first eleven. Unslingo is definitely the toughest to get. I had to work on getting it for half a day almost.
