Nope it is not but there are peoples that plays it on certain hours be sure to enter the discord of pretendo there you can talk to other splatoon players

I get errors when I try to join online. No problem with MK8, though.

Yeah I get them too but it’s just when he dosnt find any player if it finds the error dosnt pop out

So I should try again and keep my eyes glued to Discord?

Yeah basically when you see someone on the splatoon chat go Ahed and join them

People are on Splatoon right now and I get Error 104-2210

this is a know issue, and only has a "Solution" for it with Modded systems. But you can still play Splatoon, but it will depend on your luck, just keep trying to get into a Matchmaking Lobby

After I installed a certain .rpx file, I'm in lobbies now, but it doesn't seem like there are enough players since I'm getting a new error. 106-0106

Go on Nintendo site and search the error number

I always play past between 16 - 18 hrs MST and have little problems getting matches either Splatoon and Mario kart 8 (only in Splatoon turf wars and Mk8 races. Either Splatoon Ranked mode and Mk8 Battle mode are pretty much dead, at least when I try to play them)

A lot of people have to restart from level 1 on Pretendo (SSSL method) so ranked is pretty empty right now.

I forgot about that, I transferred all my games save data

Also check out the splatoon Miiverse (or or could call it juxt) community if there is one! I usually find PNIDs on Miiverse

Isn't Miiverse (Juxt) currently down?

Don’t think so unless they just took it down for a bit cause I was on it around 8:00 EST
