What each slot rewards, and what it costs to play someone out of position.
A group is seven slots. Each one weighs the eight idol ratings differently, so the same idol is worth more in one seat than another. These are the exact weights the game uses.
| Position | What it rewards |
|---|---|
| Leader Holds the group together on camera and off. | Star 30% · Charm 25% · Craft 20% · Vocal 15% · Dance 10% |
| Main Vocal Carries the chorus and the killing part. | Vocal 60% · Star 14% · Craft 12% · Dance 7% · Charm 7% |
| Lead Vocal Bridges verses and holds the harmony. | Vocal 45% · Dance 18% · Visual 15% · Charm 12% · Star 10% |
| Main Rapper Owns the bridge and usually writes it. | Rap 55% · Craft 18% · Star 14% · Dance 13% |
| Main Dancer Center of the formation, front of the fancam. | Dance 62% · Visual 15% · Star 13% · Charm 10% |
| Visual Face of the group, and of the CF campaign. | Visual 50% · Star 22% · Charm 16% · Vocal 12% |
| Maknae Youngest. Variety gold, fandom magnet. | Charm 30% · Dance 22% · Vocal 20% · Visual 18% · Star 10% |
Every idol carries the positions they actually held in their group. Jennie is a Main Rapper, a Lead Vocal and a Visual, so she fits three slots at full value. Put her anywhere else and she scores at 86%.
The penalty is deliberately survivable. A stacked idol out of position often still beats a perfect fit with weaker ratings — working out when that's true is most of the game.
The seven picks are also scored together. Stacking members from one agency reads as shared training and pays a bonus; spreading across four or more generations costs you; three or more nationalities earns Global Appeal, which feeds overseas activity and the Japan release.
What happens if you play an idol out of position?
They still play, at 86% of their value. The penalty is deliberately survivable — a stacked idol out of position often beats a perfect fit with weaker ratings.
Which position matters most?
None dominates. Main Vocal weights vocal at 60%, Main Dancer weights dance at 62%, and Leader spreads across star power, charm and craft. A lineup strong in one area and empty in another will not go 52-0.
What is chemistry?
A bonus or penalty on the whole lineup: stacking one agency pays off, spreading across four or more generations costs you, and three or more nationalities earns Global Appeal.
