Big Sale is a temporary event that consists of several stages. Every stage has a task that will require you to collect yellow pieces on the game field. Each task has a reward, and completing one opens a new challenge. Activate the Golden Key to gain access to better rewards. The more stages you complete, the more prizes you earn. Complete all the tasks to get the grand prize!

IMPORTANT NOTE:
- All players at level 17 and higher can participate in this event.
- The event doesn't feature special levels—just keep playing from the level you were at in the game.
- You can only reach the grand prize if you've completed all the previous stages.
