In each run you guide a raw crystal through grinding and shaping stages, avoid spikes and hazards that chip away at your gem, and add decorative touches to build a finished diamond. The goal is simple: keep your gem intact, pass obstacles with precise timing, and create the biggest, most polished diamond possible.
The game blends easy to learn controls with timing and position challenges. Levels are short and packed with action, making Gem Stack a good pick for quick play sessions or high score runs. Visuals use a clean 3D look to show each stage of the crafting process, while the obstacle layouts test your reaction and planning.
