Update 2023.04.07: - now error toast messages are shown for invalid moves with an explanation why the move is impossible (you can turn this off in options) - the game now detects when there are no moves available and shows a "game over" popup. Also when the same position on the table repeats for the 3rd time - more backgrounds, more music (you can now select which tracks to include in the shuffle) - more solitaire types (101 now)
