Tap the Hot Air Balloon icon on the Home screen to start a Puzzle level.
Swap neighboring pieces (red hearts, yellow stars, etc.) on the board to join 3 pieces of the same color and clear them.
You can only swap as many times as you have Moves, as displayed in the top-right of the screen.
Complete a level by meeting all of the Targets displayed in the top-left of the screen.
The targets are known as Trick Pieces, and require actions such as clearing neighboring pieces, or using Mana Gifts or Magic Items to clear.
The number of moves available in each level is fixed, and when it reaches 0, you fail the level.
By paying coins after failing a level, you can buy additional moves and continue playing.
