NN567Calwen is a vertical spirit merge mobile game that combines drag‑and‑drop merging with task submission mechanics. Players control four types of spirits—flame, mist, thorn, and starlight—on a 4×5 board, dragging spirits of the same type and rank together to merge them into higher forms. Each successful merge refreshes new spirits. Dragging a fourth‑tier seal into the submission area and delivering them one by one according to random task requirements advances the wave of tasks and accumulates points. Operation mistakes trigger vibration feedback, and the round ends when the board is full. The rules are clear and the pace gradually intensifies, making it easy to pick up while also testing spatial planning and strategic merging routes.
