When a marble is launched into one of these holes, the slot spins. If three of the same icon match up, the icon appears in the slot. The icon can be a silver, gold, or other color coin. Silver coins give you 5,000 points, gold coins give you 10,000 points, and other coins give you 50,000 points. You can also get a timer that sends marbles back a little bit (very convenient), or a detonator. Sometimes you don't get anything. Slots only appear in Quest mode.
