Operating a toy crane machine involves several ongoing costs beyond the initial purchase. First, electricity is a constant expense, though typically modest for a single unit. Second, you must regularly replenish prizes to keep the game attractive, which constitutes a significant recurring cost. Third, maintenance and repairs are inevitable; parts like claws, joysticks, and circuitry may need servicing or replacement. If the machine is placed in a commercial location like an arcade or mall, a percentage of revenue or a fixed site fee is usually required. Additionally, consider costs for licenses, insurance, and occasional software updates. Proper budgeting for these ongoing expenses is crucial for running a profitable and sustainable toy crane machine operation.
