Nova Jewel

Nova Jewel is a Vietnamese-language crystal merge puzzle built around a personal treasure hunt. Players place gems on a five-by-five board, fuse identical stones into rarer crystals, and chase chain combos that culminate in Lucky 88 wild gems and Nova bursts. The run is tied to a living catalog, a gem codex, a once-a-day vault, and an achievement track, so every merge both scores and expands a collection that cannot be found in a generic match game.
