Follow directions on the blue part to eat. Click on the coin, put it in the slot, and if it is a quarter (we don't use it in Australia.) or 25c, you can click on one of the red squares, they are Smarties, Gumballs and Maoam. The other coins are the Nickel(5c), Penny(1c) and Dime(10c). They are not Australian. If a sneaky crook tries to use these coins, and not the Quarter, it will fall into the machine, then it will reject. Until you pull secret compartment, you can then take the lock, then if you click on cover when it's unlocked, it will say, "Yes sir," and then you can see the Quarters. To take them back, hit space bar to keep them.
