Happy Boss Pull Pin turns every level into a sharp physics puzzle. Pull the right pins, steer your grinning boss through danger, and scoop the diamonds. Study the layout. One wrong tug and you're toast lava surges, darts whistle, and traps snap shut. Your timing are everything. Be patient, then strike: block hazards with clever pin orders, reroute molten streams, and carve safe corridors like a pro. Each stage is a fresh contraption with its own twist. Some make you bait dart shooters, others force you to juggle multiple triggers or delay a pull until the last heartbeat. Risk is real, mess it once and the boss is done. Got the nerve and the craftsmanship? Hit Play and make your boss leave every level happy and rich.
