Tip 1: Do not tap an item as quickly as its discovered. Instead, use a long time to discover all or the majority of the items. Start tapping them to get combos to enhance your last score and make stars quicker.
Tip 2: Enter the Store and see marketing videos or complete offers to make gems.
Tip 3: Bones or Wolf's Bane can be used to reveal an item you can not discover. They are tough and costly to get. Save them for use throughout really tough scenes, such as the last star of the game or when you need to keep constructing the combo meter.
Tip 4: Log in daily to get bonuses. You will certainly need to play a brief concealed item scene to make them.
