For a toy crane machine, or claw machine, to operate stably and safely, the surface it sits on is critically important. The ideal surface is perfectly level, firm, and solid. A flat, hard floor—such as concrete, tile, or a level wooden subfloor—provides the best foundation. This prevents the machine from rocking, tilting, or wobbling during play, which is essential for both the accuracy of the claw mechanism and the overall safety of the unit.

Carpeted or uneven surfaces are generally not recommended. Soft flooring can allow the machine's feet to sink or shift slightly over time, compromising its balance. Even a minor tilt can affect the internal calibration of the crane, making it difficult for players to win prizes and potentially putting stress on the machine's structure. Furthermore, an unstable machine poses a tipping hazard, especially if it is bumped or if players lean on it.

Therefore, whether setting up in an arcade, family entertainment center, or retail location, always ensure the surface is thoroughly checked for levelness before installation. Using a spirit level during setup is highly advised. Some machines may have adjustable feet to compensate for very minor imperfections in the flooring. Ultimately, a stable, level surface ensures consistent gameplay, protects your investment, and guarantees a safe environment for all users.
