Settings and features commonly available include: Claw strength and aperture Claw movement speed, either as a whole, or in individual axis. Pick-up strength (on skill-based machines) Primary and secondary strength settings Toy teasing on payout based machines—when toy teasing is enabled, the claw will pick up a prize for a set amount of time before dropping it, giving the player the impression that they nearly won Operator adjustable payout rate: The percentage of how often the machine will pay out a prize in relation to the value of the merchandise and the operators preferred profit. Overpay: If the machine pays out over a certain number of prizes in a set amount of time more than its set payout, it will throw up an error code, and prevent anyone from inserting money, and prompt them to get an attendant. This eliminates the possibility of people emptying a potentially faulty machine. Instant Free Play: When the machine will give the player a free play if enough money is inserted. This is popular on ICE, Cromptons and Brents X-Factor machines. Instant Replay: When the player can drop the claw in the exact same position before it has returned to the home position, at the cost of one credit. The feature is disabled if the user has less than two credits. This feature is popular on the Elaut Intelli or IntraXion machines. Older machines are known to be retrofitted with devices called crane processors. This gives skill based machines the necessary technology in order to be rigged. The best and most common version of this in the UK is the Lottelle "The WON" processor. Processors are most popular in the UK, where small arcades choose them over replacing their machines. Some cranes are also able to display the number and value of prizes won in a given time period, enabling the owner to keep track of how profitable the machine is for them. Claw machines holding expensive prizes, such as a video game console or a mobile phone are typically programmed so that the grip strength of the claw is determined according to a payout percentage that is profitable to the operator. Experienced skill crane players also say that box shaped prizes are among the most difficult kinds of objects to pick up
