Tiered rewards reward you for taking part in mini events. Each time you do something in the game linked to the current event that is happening, it will build up your rewards! Examples include: spinning the Tailor of Fortune, opening Carpenter Crates, and opening suitcases.
You will see the competition name, details on what it will take to get points, how many more moves you need to get to the next level and any completed levels that you have done.
