The popular multiplayer Minigame on Minecraft called the challenge games by popularmmos. This is a game where you open up a certain amount of lucky blocks (one of the mods in the modpack) and collect things from them to trade them in for better things such as a beacon for the best weapon obtainable and armour for a certain amount of emeralds depending on how essential the armour is to survive. After opening up all the lucky blocks and trading in all the things you've gotten from the lucky blocks; (which by using addons such as the spiral lucky block to get better/worse drops for the game) you fight either a custom boss battle from a mod (such as twilight forest adding in things such s the hydra) or fighting each other. There are different types of challenge games; there is the explosive challenge games where you can trade in items from lucky blocks for explosives to try and blow up your opponent (you have to fight a player in this mode) and the gun challenge games where you download and install a gun mod (e.g vic's modern warfare or mr crayfish's gun mod) and use them to shot your opponent down.
