A while ago a few people organised an unofficial "Weekly Game" where people would try to come onto Scraps multiplayer at the same time to play together. These have been going on for a while now and they're sometimes more popular than others, but if you're looking for people to play against, coming on at one of these times is probably your best bet:
- The main one is at midnight Saturday UTC. That linked Steam event will automatically adjust its timezone to match the region you have set in Steam if you're logged in.
- If that doesn't work for you, there's an alternate time 12 hours earlier at midday Saturday UTC.
There's no official server to join - either people join one of my official ones or they create their own with custom settings. Again these are just unofficial things - no guarantees of attendance - but it's been good fun in the past.
