While playing a puzzle, coins can be used to purchase two kinds of assistance:
1. Shuffle tiles: This causes all the remaining tiles on the board to be shuffled, opening up new valid moves. It can be selected by tapping on the pink icon in the status bar area.
2. Undo last move: This returns the last two tiles that were removed to the board. It can be selected by tapping on the red icon in the status bar area.
These is no limit to the number of times these options can be used in a puzzle, provided you have enough coins to purchase them.
Coins can also be used to replay completed puzzles, or to automatically complete quests or claim trophies.
