Used to be fun – Push Mahjong-solitaire puzzle Review

I have had the game for several months. Fun, challenging. Now it has started having games that cannot be won. The board gets down to a dozen or so tiles and there are several tiles that do not have a matching tile on the board. I don’t mean that I’m not able to slide them to make a match, I mean there is ONLY ONE of that tile even showing on the board.
