Knowing when the prize compartment is full on a toy crane machine can save you time and tokens. Look for these clear signs. First, check the prize chute or drop area. If you see prizes stacked to the very top, visibly blocking the opening, it's likely full. Sometimes, prizes may even be jammed in the chute, preventing new ones from falling through. Second, observe the machine's behavior. If a prize you successfully grab gets stuck at the drop hole and doesn't fall into the collection bin, the compartment might be too packed. Third, listen. A full compartment might produce a muffled thud instead of the usual clatter when a prize drops. What should you do? Inform an arcade attendant immediately. A full machine is often out of service until emptied, and they can reset it. Trying to play a full machine is usually a waste of money, as won prizes cannot be retrieved. For better success, play at well-maintained arcades where machines are serviced regularly, ensuring the prize compartment is properly managed and ready for play.
