I'm enjoying my very first Pachislo- Lord Of The Rings. However, it's set to level 1 and I would like very much to know how to adjust the setting. So...does anyone know where the odds/skill button on this machine is...I've searched extensively but have had no luck finding it. If someone could please point me towards it, I would greatly appreciate the help. A picture with it circled or a very detailed description please, as I've already done my best (but to no avail) to check "on the door" and "around the power supply"...Thanks!
