This is a very rule heavy game. Here are the rules!
Rules:
There are a few requirements before starting the game:
First you need to make a wheel for choosing which gun crate the winner gets. I recommend wheelofnames. Here are the choices it should have:

After you are done making the wheel each person should get diamond armor and tools with an iron sword with these enchants. Here they are: (Note: This is included in the pre-made world)

Those are the requirements before starting the game. Now here are the rules to play the game:
My recommendation of players playing the game is 3-4 players to play the game (2 can play but is not recommended)
Now to the player's preference you can have more than 4 players but like 2 people, its not recommended.
There will be a clockwise rotation of however many people are playing. Somebody will make a challenge. Whoever wins that challenge will get a gun crate. Whoever is in charge of the wheel will spin the wheel, whatever gun crate or gun type it lands on is the type of gun crate the winner gets.
Welp! Those are the rules for now. Have fun playing the minigame! (Rules are subject to change)
