The rhythm game component of T7S involves tapping star icons on the screen as the music plays, and there are different types of icons. The icons appear in random locations, so each play is a new experience. There are three difficulty levels: easy, normal, and hard.
Lessons are used to strengthen your idol cards.
Group lessons are used to increase the stats of your cards. The supplementary cards used will be consumed.
Special lessons are used to increase the maximum stats of your cards. This is done by combining two identical base rarity cards. There are three base rarities of cards: G (Gold), S (Silver), and B (Bronze). When cards undergo special lessons, their rarity increases to GS (Gold Star), SS (Silver Star), or BS (Bronze Star) depending on their original rarity. The artwork on the card also changes.
Item Produce is where you can give presents to your idols to raise intimacy levels. Items can be obtained while scouting.
Scouting is done to recruit candidates to become future idols. Scenarios are unlocked as you scout out each zone. When scouting, you may tap anywhere on the screen to progress the search and gain gold and XP. Item icons will appear and fly back and forth across the screen; tapping them successfully will reward you with an item which can be used for Item Produce. You can also randomly run into other players, and either send them a friend request or exchange greetings with them.
While scouting you can also find Collect Items which are fragments of cards. Collecting all six fragments will reward you with a limited idol card. However, each player can only find three types of fragments from scouting. The other types must be obtained by winning battles against other players.
