My first match, I got to the point of a draw, where the game quickly flashed the message "UNENTSCHIEDEN!" (draw?) and forced me to play again. Only this time, I couldn't flip any cards, and my opponent couldn't flip any of mine, and they just flipped at random. Also, the left space would not accept cards as this was declared an illegal move, so I had to quit the game when the rest of the board was filled up.
Otherwise though, it's fun. I always liked Triple Triad, though I've never been very good at it.
