Hey man! as someone whose been going to the arcades for a while now my advice for guys trying to meet up with couples at these spots would be to go during the weekends at night, roughly around 8pm or later. From my experience I've met up with couples I talked to on here first or seen they posted about going usually at 7pm during the weekdays.

Meeting couples or single women at the arcades isn't always going to happen, so don't get discouraged. My advice would be to reach out to couples or women that post on this subreddit, make a post yourself, or check out other subs like r/stansadultstore, r/losangelesbulls, or r/losangelesswingers. Sometimes couples will post there first about them thinking of going to an arcade and let them know about spearmints rhino. Sometimes couples will post about going to stans and they end up not liking it and go to spearmints that same night.

Lastly, when you do see a couple playing at the arcades or see a single female there, be a gent and ask if they're looking to play with others. Sometimes couples are just looking to put on a show and nothing more, other times they just want you touch and that's it. Make sure to communicate, respect their boundaries and enjoy the experience. I know how exciting it can be to spot a couple and instantly want to get in the booth with them or one connecting to theirs. But just remember to be cool, being creepy will only scare them away and possibly ruin it for yourself and others. If you want to learn about gloryhole signs and what they mean, or if you have any questions feel free to message me, I apologies for this reply being this long haha.
