Selecting the proper toy sizes for your crane machine is crucial for both player satisfaction and operational efficiency. The ideal toy should be large enough to be visible and desirable, yet small enough for the claw to grasp effectively. A good rule of thumb is that toys should be no larger than 2/3 the width of your machine's prize chute opening. This ensures successful dispensing when won while preventing jams.

Consider the claw mechanism's strength and opening width when choosing toys. Bulkier items may require special positioning or weaker grips to maintain game balance. Mix different sizes strategically - place larger "premium" prizes in harder-to-reach positions while keeping standard-sized toys throughout the machine. Standard capsule toys (2-3 inches) work well for most machines, while plush toys should be compressible enough for the claw to secure.

Always test new toy selections by running several practice grabs. Observe how the claw interacts with each item - it should be able to lift prizes consistently but not too easily. Proper toy sizing creates the perfect balance between challenge and reward, keeping players engaged while maintaining your machine's profitability. Remember to check local regulations regarding prize sizing requirements for amusement devices.
