The Idolmaster: SideM - Live on Stage!

About

The Idolmaster: SideM - Live on Stage! is a mobile music game where players build and perform with idol teams. Core gameplay revolves around 315 Lives that require LP items to launch. During performances, you tap, hold, or swipe rhythm icons as they approach a cursor. Support moments let Idols boost scores with appeals, while Kizuna mechanics let paired Idols combine appeals for bigger effects. Maxing out bonds between characters unlocks special in-game descriptions that highlight their relationships. The game adds new SSR cards and full illustrations for both SR and SSR tiers. Card progression splits into regular Lessons for leveling and Special Lessons that use P Memos to change outfits and boost stats. Duplicate cards directly increase the original’s power and level cap, streamlining growth. While mobile-focused mechanics feel dated by 2024 standards, long-time fans of the franchise note the deep idol customization and bond-building system remains a standout. The 2017 release still holds a niche audience on Android and iOS, with over 500,000 downloads tracked across platforms.
