Selecting the right prize sizes is crucial for the success of your toy crane machine. The ideal size depends on your machine's claw strength, prize compartment dimensions, and target audience. Generally, prizes should be large enough to be desirable but not so large that they jam the machine or are impossible to win. A good rule is to use items that fit comfortably within the claw's grasp—typically between 2 to 6 inches in height or width. Mix smaller, easier-to-win items with larger, premium prizes to keep players motivated. Always test the claw's ability to lift and hold the prize securely. Avoid overly heavy or irregularly shaped items that can frustrate players. Regularly rotating prize sizes and types maintains excitement and encourages repeat play, directly impacting your machine's profitability and customer satisfaction.
