3D Bolt Master®: Screw Master®
3D Bolt Master removes colored screws from rotatable objects and places them in matching boxes.
Consider for spatial sorting with limited spare holes
Rotating the model reveals screws while temporary storage creates planning pressure.
Keep in mind: The ad-free pack removes forced ads while rewarded ads remain optional; event rewards are in-game benefits.
