Here are two games I thought would be cool to add on to the server!
1. Guess Who?
2. Master Mind

Both use command blocks, but I'm pretty sure there's a way to make it so that plug ins or something work for it if I remember correctly from what a staff member said.

Guess Who is like the classic game guess who but in minecraft! It currently uses some minecraft related heads and youtuber heads. Also, if someone really wanted to, they could change it up so that the heads were those of staff members on the server. The only bad thing about this game is that some people could cheat and say wrong things on purpose.

Master Mind is a game where a random code is selected and you have to try and get the exact same pattern. Sometimes a color even repeats! Are you a master mind at Master Mind? If this gets added to the server, then find out!
