In Royal Belt Defense, you take on the role of a powerful royal defending your kingdom from waves of invading monsters. But instead of fighting directly, you control a belt machine that continuously moves troops and items into battle. Your goal is to strategically manage your army and defeat enemies before they reach your defenses.

You can choose your army from different unit types, each with unique abilities. Alongside your troops, use items and power-ups on the belt to enhance their strength. To gain an advantage, you can also set up multiplier machines that boost your army’s power as they pass through the belt.

The belt never stops moving, so quick thinking and smart placement are key to victory. Every decision you make affects the outcome of the battle. Can you master the belt machine and protect your kingdom from destruction?
