Is tile selection random?
Often the perfect tile arrives right after you’ve placed a less ideal tile in a spot. If you are lucky not to put the tough-choice tile in the most logical place then the second, ideal tile is helpful. However, it regularly happens that you make the logical/sacrificial choice, only to have the ideal tile come up as the very next one. Not sure if this is by design, but it can feel quite frustrating and discouraging when playing Classic mode. It happens too often to be coincidental in my experience.
