PlusROM High Score Club

Standard: Each match adds to the progress bar until you reach the next level.
          The game ends when you run out of moves. Each level gets longer as you play!
Timer:    The progress bar starts full and slowly depletes over time. There is only one board to
          complete, but every match advances to the next level! If you run out of moves, the board
          reshuffles, and the game only ends when the progress bar reaches empty.
Blitz:    The progress bar starts out half full and depletes quickly. Each match fills the progress
          bar, giving you more time. The level is increased at timed intervals. If you run out of
          moves, the board reshuffles, and the game only ends when the progress bar reaches empty.
Left Difficulty Switch selects either 7 or 8 block colors (increases the difficulty).
