Placing a toy crane machine on a carpeted floor is possible, but it's generally not the ideal setup. For optimal stability and performance, a hard, level surface like hardwood, tile, or laminate is highly recommended.

The primary concern with carpet is stability. The machine's weight can cause it to sink or tilt slightly into the plush surface, leading to an uneven base. This can affect the machine's internal leveling, potentially causing the crane to misalign with the prizes below. During vigorous play, the machine might also rock or shift on a soft carpet, posing a minor safety risk and frustrating users.

Furthermore, moving the machine for cleaning or rearrangement becomes significantly more difficult on carpet. The casters or base will catch on the fibers, making it a hassle.

If you must place it on carpet, choose a low-pile, dense commercial-style carpet. Placing a large, rigid board (like plywood) underneath the machine's entire footprint can create a stable, temporary hard surface. Always use the machine's adjustable feet to level it as best as possible.

For the best experience—ensuring fair play, long-term component health, and safety—a hard, flat floor is the superior choice for your toy crane machine.
