Quoted from jdapolito:
They don’t look like resistors I have ever seen but I’ll look again with magnification and see the color scheme of the bands and see if I can read the resistance from that
They are called wire-wound resistors. Not sure if they are even going to have the color code marked on them. You can use any kind of resistor as long as they have the correct resistance and wattage rating. They are not used on all games (and not in many circuits as far as that goes), but I have a Royal Flush and a Super Soccer that have them and they both use 470 ohm, 2 watt resistors. They all serve the same purpose and are used at the same voltage, so I would bet that's what you have in your machine. You should be able to use a multimeter to check their resistance.
If they are open (hard to believe they would all be open), it really wouldn't prevent the circuits they protect from functioning (they are wired in parallel), but you would be getting severe arcing from the rotor contacts to rivets (due to back EMF) as the rotor sweeps around them and that causes damage to the relatively soft brass material used on these units.
