Selecting the ideal toy sizes for your crane machine is crucial for both player satisfaction and your operational success. The key is balance. Toys should be large enough to be desirable and visible, yet not so large that they jam the machine or are impossible to win. A good rule is that the toy's dimensions should be at least 25% smaller than the crane's claw opening. This allows the claw to grip the toy effectively. Popular choices include small to medium plush toys, capsule toys, and medium-sized collectible figures. Avoid very flat, overly round, or extremely heavy items, as they are difficult to grab. Test different sizes during setup; a properly sized toy should be liftable and movable by the claw without excessive difficulty. Ultimately, offering a mix of sizes within these parameters creates an appealing challenge, encouraging more plays and repeat customers.
