Gemstones Rush Mania is a fast-paced puzzle game where you drop square gemstones into four columns, aiming to align and clear full rows for points. The closest row to the player must be perfectly aligned to disappear, triggering combos if rows below are also aligned. Occasionally, wooden blocks appear, requiring two hits to break before the row can be cleared. As the game progresses, the speed increases, making it more challenging. How long can you keep up, and what high score can you achieve?
