Slot machines for home use have been gaining in popularity due in large part to the Japanese company Pachislo selling its legal versions to American consumers. The Pachislos are dubbed "skill-stop" slot machines because the player manually stops the reels from spinning. Although similar to commercial slot machines in mechanics and appearance, the Pachislos are designed specifically for private entertainment -- not for gambling. With that in mind, you may want to convert your machine to accept quarters as well as Pachislo tokens. The conversion is simple and shouldn't have any negative effects on the machine if done properly.

Skill level:
Moderately Easy

  1. 1

    Shut power off to the machine. Turn the power switch to "Off" and unplug it from the wall outlet.

  2. 2

    Open the front of the slot machine with your slot key. Turn the key counterclockwise to release the lock.

  3. 3

    Locate the coin control mechanism. Look for a large rectangular box with about eight wires coming out of it.

  4. 4

    Disconnect the wires from the circuit board. Unplug all of them from the rest of the machine and let them hang freely from the coin control box.

  5. 5

    Detach the box from the machine by squeezing in on both horizontal ends and pulling out. Flip the box over and set it on a flat surface.

  6. 6

    Loosen the two screw and washer sets connected to the metal strip on the back of the box. Reposition the screws so they sit in the middle of their respective slots and retighten them.

  7. 7

    Replace the box in its former position and plug it back into the circuit board. Shut the door, plug in the power cord and turn on the machine once again.

  8. 8

    Check to make sure quarters will pass through the coin slot. Otherwise, repeat the previous steps and reposition both screws in the proper middle position until the machine allows quarters through.

Tips and warnings

  • Failing to turn off the machine before adjusting anything could result in electric shock.
