Ghosts of Mistakes: Sort a coin wrong or let one slip past, and it comes back a few seconds later as a ghost. Sort the ghost right and you win back a life, or double its points if your lives are full. Miss it and it returns faster, up to three times. The game-over screen counts the ghosts you redeemed, and How to Play has a new page about them. Sound: Coins clink when you sort them right and buzz when you miss. You'll also hear the discard chute, wave clears, upgrade picks and the end of a shift. Tap Sound Off in the menu to mute it. We also refreshed the store banner.
