Prism Blast 3D is a fresh take on block puzzle — played on a round 3D board instead of the usual square grid. Drag blocks onto the rings, line them up to blast whole rings and spokes, and keep the creeping grey junk from closing in. Chain clears for combos, spend power-ups when you get stuck, and work through score, junk-clear and survival goals. Easy to learn, satisfying to master.
