First to find/click Block wins

First and maybe the most important is to make a maze, WorldEdit can save you so much time. Time that you can spend on perfecting the maze instead.

Is your config.yml empty? Click the link.

Make sure the following is set in the config.yml, or edited to your needs.

#The game mode type for the arena
#Values: "collectItems", "findBlock"
mode: "findBlock"

#The block you must find
###Used in mode "findBlock" only###
blockMaterial: GOLD_BLOCK

IMPORTANT: all points are the block you stand on!

Mark your square /maze set pos1 and /maze set pos2

Create a spawn point with /maze set spawn

Now to add some triggers (blocks that will activate on touch):

Player cought on fire: /maze trigger add Fire
Player hit by lightning: /maze trigger add Lightning
Mob spawning and attacks player: /maze trigger add Mob
Players gets poisoneffect: /maze trigger add Poison

With that done, all you need to do is be the first to type /maze join and your server should advertise for more to join.
