All coin activated arcade machines have a built-in coin comparator computer that you can train to certain types of coins or tokens. All machines can also be put into free play by setting the menu to the correct option. To train a coin comparator you can simply insert the coin or token you wish to collect. The comparator will use this example token or coin as reference and will accept similar coins while rejecting coins of different sizes.You can use our special arcade tokens to operate the machines or you can use real money like 50ct pieces or euro coins.
