Agreed. I had it reduced to a single tile available, yet there was no way to win. Every new tile matched one above or to the side of it.

Co-developer here- Not quite. It is possible, but you have to have the right kinds of tiles in the right positions. I won't give away the algorithm, but I do know it can be beaten. Not easily, perhaps, but certainly possible.

Can confirm, have just beaten it a few times.
