You get one point for every tile removed, so your score will always be an even number between 0 and 144. Some patterns are easier than others, so a high score doing one pattern may not be comparable to a high score with another. Your score is listed as a set of two numbers, seperated by a slash. Because undo-ing puts tiles back on the board, it will make your score go down. The number before the slash is your current score. The number after it represents the highest score you have gotten to in this game.
