Depends is it a 20amp or 15 amp

dmd games normally is 3 for 15 amp 4 for 20 amp

Older games normally 4-5 for 15 amp , 6-7 for 20 amp

I keep it to 5 per 20 amp and haven't blown a breaker yet. Mostly LED games and all eras. And that's with them all being played at once too and some having magnets.

You can run 5 all day long. Enjoy.

Keep in mind... nobody mentioned what ELSE is on that circuit. A single outlet may be part of a larger circuit with other workloads. They may not even be in the same room.

Turn all the lights in the house on and flip the breaker off. Confirm what changed. Other outlets in other rooms may be more tedious to track without testing each one. Focus on big draw devices (washer, dehumidifier, etc).

Are you sure that single outlet is 20A? Most are 15A individually with 20A passthrough on the circuit.

Ohhhhhhh.... I was thinking residential.

Stopped counting after a while.

Keep adding til it all goes PPhut, then one has found the tipping point

My advice was assuming that nothing else would be on the 20 amp circuit.

Could always use the old penny trick. Works, but let's face it. Is your fire insurance paid up?

Sealclubber is on track. Just because it's a 20 amp breaker doesn't mean you have 20 amp outlets. More often than not they are 15 amp outlets.. i would not plug 5 games into a single outlet and play them all at the same time. I have run 6 dmd games off 1 20 amp breaker plugged into 4 separate outlets without issue. If your running everything off 1 outlet I'd advise spending a couple bucks for an electrical upgrade, before risking Any other damage

What's the issue with one outlet per breaker? I thought it was more convenience than anything. I have five games in a surge protector plugged into one outlet that is ran by one 20 amp breaker. This is the only outlet on that breaker.

If there is only one outlet on a 20 amp breaker, the outlet must be rated for 20 amps per NEC. We are allowed to use 15 amp outlets on a 20 amp branch circuit because the notion that your never only going to use one outlet.

Oh okay. But since I have a 20amp outlet I'm good?

Yes. You can tell by the horizontal/ vertical prong on the hot side.

I'm a electrician...and I can say that this is not true. Your breaker must be sized according to the device with the lowest amperage rating. A easy way to tell if you have a 20 amp plug is to see if it the hot and neutral only run vertically, a 20 amp plug has a vertical and horizontal slot.

No, not true, your allowed to put a 15 A receptacle on a 20 A circuit. You see it all the time in kitchens. 20 A appliance circuit but the duplex receptacle is only 15 A. Residential code.

article 210.21 (B) 1, 2, and 3 of NEC.
Yes duplex outlet (two plugs) is already considered "multiple outlets" so it's permitted on a 20amp breaker. Part of being a UL listed outlet includes that a 15 amp duplex be capable of feeding through 20 amps of current.

Other things to consider, hopefully a 20 amp circuit uses #12 gauge wire and the outlets are not "backstabbed".

Touché, you are correct sir, it's amazing, I've been a commercial and industrial electrician for 20 years and I still learn new things all the time

I have 7 in the same room along with a popcorn machine. My house is newer and there is only one AFCI breaker for that particular room. The funny thing is that when there are a bunch of people playing, the lights in the hall bathroom dim every time a flipper is hit.

I'm guessing someone wired the bathroom lighting with the bedroom outlets.

My new game room has one 20A for every 3 outlets.

No worries. Had to find the reference after you said wrong to make sure I wasn't giving false info.

If people are making game rooms you can have your electricians wire the upper outlet of a duplex to one 20 amp circuit and the lower to another. That way you have two circuits at every outlet to even out the load.

That being said I have a police force, high speed, and baywatch on 1 15 amp circuit and all is fine. No led in the sys 11's yet.

Another thing too is most libraries have kill-a-watt Meters to checkout to find peak power consumption of what's plugged into it. That exactly will tell you which games can on on a particular circuit

Amateur.

We have been running around 19 in the same room for years.

However, no popcorn machine. ---- Hmmm.
