How to play Minecraft party games?

I've recently seen Joey Graceffa playing on Minecraft party games on YouTube where you can play online with other players on games like, wool mix up, red light green light, spleef, dead end and a horse race. I really want to know if and how I can get this…
Is there just different servers you join, if so what are they called?
Is it even possible to play them?

Any advice will be much appreciated

I need a mc professional spawn builder for my new server! Any takers?

I have a minecraft server, a small server (1-20)players, and we just want a awesome spawn. We need someone who doesn't, grief, hack, cuss out other players, and isn't annoying about getting op every 5 seconds. So can anyone help us with that?

How to i ban players on my minecraft server?

I have a server that i bought from gameservers.com and it came with McMyAdmin 2 and every once in a while a very bad person that hacked my server IP joins and does the best in his / her ability to destroy our stuff (we play on survival). I might be a major noob for this but i don't know how to ban players on it. What i really need to know is how do i make my Minecraft account an admin so can type in the commands to ban people. This will Really help with getting this guy to go away.

Good group computer games?

My roommates, friends, and I when we got bored play minecraft on our minecraft server we made, but now that we have a huge city, towers, and vaults (On survival - hard) we're getting really ******* bored.

What are some good group games to play that'll be really fun? The only other games I can think of would be World of Warcraft (Which would be hard to get them all into) or a few custom games on starcraft 2 or warcraft 3, and I'm not sure if everyone would enjoy those as much as I do.

Prefer ideas that can be run as LAN and not online with others, and most of my friends arn't as nerdy as I'm, so things like RTS are probably not going to float well with them, but still recommend them if you feel it's a good idea. Also prefer chill / relaxing games with a bit of action to full competitive games like CoD.

What tablet should I get?

I need a tablet that can play minecraft desktop version. I will be playing occasionally and do not expect great performance. I already have a nice desktop and a good laptop but I need a tablet for school and such.

Needs.
windows 8/8.1
comes with Microsoft office.
can play minecraft on all low settings and render distance normal/6 Minimum
run unity 4.0 just for learning purposes. I will not be rendering or playing or testing it. I'm just gunna get used to the interface and stuff.
I need a keyboard preferably a snap off one.
my price range is $0.00 Usd - 425 Usd.
I will buy from any website as long as it is a new product!
I have considered the asus transformer book t100 on best buy, but the proccesor is a little bit of a drawback. But if it can play minecraft smoothly at those settings then I'm fine

thank you in advance

Added (1). I'm not looking for a tablet to get 100+ fps. Just one that can run it like around 30-40. It will not be playing single player that much at all. Mostly servers.

How to fix lag on computer?

I play an online game called Combat Arms. I have no lag until my little sister plays minecraft on servers, from her own computer. Is there any way i can make her only use some of the internet, while i get more of it so i do not lag?

Added (1). I did give myself high priority for QoS and her a low priority. It still lags.
