I’m having a Halloween party and my friends said they wanted little activities and games?

So like I’m definitely going to have a hide and seek or a tag game something like sardines (if you know what that game is…) but I don’t know what else? There’s probably going to be about 15 people there so…? any

I need some really cool games for a Halloween Party i’m having. Everyone is between the ages of 11-14.HELP!!!!?

Everyone is between the age of 11-14 and it’s an outside party with a huge yard and we are only gonna have about 1 hour to play some games.
