Jewels fall from the top of a vertical well in groups of three. Move the falling group horizontally, adjust its arrangement, and place it so jewels of the same color form matching lines or connected groups. Completed matches disappear and create room for additional pieces.

The objective is to survive as long as possible and earn a high score. The main challenge is managing the stack before it reaches the top of the field. Play is built around continuous single-player rounds, with increasing pressure from the falling pieces rather than a story campaign or character progression.

Keep the center and lower rows organized instead of building tall uneven columns. Make matches that clear several jewels at once, but avoid leaving isolated gaps that are difficult to fill.

Plan the position of the entire falling group before it reaches the bottom. When the field becomes crowded, prioritize immediate safe clears over elaborate setups, and use the sides of the well to preserve space in the center.
