Grapple Boss: Crane Simulator

Grapple Boss is a hands-on 3D crane simulator set in busy ports. Control a grapple machine, grab scrap and steady each load before you release it. Fill a truck evenly, feed a conveyor and guide your load into a narrow silo.

Speed matters, but control matters too. Spilled scrap and hard collisions cost points, while consecutive clean drops build your combo.

BUILD YOUR PORT CAREER
Take jobs in ports across Türkiye and the USA. Earn money and reputation, unlock new cities and improve your machine in the garage. Upgrade the hydraulics, slew motor, grapple cylinder and damper to suit the way you work.

MASTER TWO-STICK CONTROLS
Rotate, extend and lift the boom, then open and close the grapple. Swinging loads, changing weather and different shifts give each job its own rhythm. Adjust your controls and choose the camera view that works for you.
