BalanceSort

BalanceSort is a vertical spirit-rune merge puzzle mobile game that combines drag-and-merge mechanics with task submission. Players manipulate four types of spirits—Ember, Mist, Thorn, and Starlight—on a board, dragging spirits of the same level together to merge them step by step, ultimately forging fourth-tier sealing runes. These high-tier runes are then dragged into the submission area above, where they are delivered one by one according to a random task list. Completing the entire set advances to the next level. Points are earned from successful merges and task rewards. The challenge ends when the board is full. The pace is relaxed yet requires planning space and merge order, making it easy to learn yet strategically rich.
