It is not necessarily illegal to put money in a claw machine, but it may be against the rules of the establishment where the claw machine is located. It is important to read the posted rules and regulations before using a claw machine, as some establishments may not allow the use of money in the machine. Additionally, using money in a claw machine may not always be the most effective way to play, as it can be difficult to control the claw and retrieve a prize. It may be better to use tokens or coins specifically designed for use in the machine.
