解歌系統
 | 此條目或章節需要時常更新。 |
Arcaea的解歌系統目前分為五種。在技術上，這五種解歌系統可並存，實際上有所出入。
殘片解歌系統
殘片解歌系統是Arcaea中最為普遍的解歌系統。目前除Stellights Collaboration包之外，所有包均有本解歌系統。
殘片（Fragments）是Arcaea中的虛擬貨幣，獲得它的方式一是進行普通遊玩、二是世界模式的獎勵。殘片是殘片解歌系統的重要組成部分，也是殘片解歌系統中唯一解歌方式。
殘片解歌系統是所有解歌系統中最終的解歌系統，技術上可與其他解歌系統並存，但遊戲中不與記憶源點解歌系統—單曲解歌並存。
殘片解歌系統體現為玩家需要通過殘片購買某些曲目的難度，在遊戲中，PST難度沒有殘片解歌系統（但γuarδina和GLORY：ROAD是個例外），PRS和FTR難度使用本系統較多。
單獨譜面的殘片解歌系統請參閱曲目列表，以下為Arcaea殘片解歌系統全表，只有PRS/FTR信息。如果本曲未在本表出現，則意味本曲在殘片解歌系統中白送。
