"Pouring Sands" - Minecraft Competitive Gamemode Map

This is a competitive game I created called "Pouring Sands." Players must survive in an 2-8 player FFA in which sand is falling from beneath their feet and on top of them from above. The last player standing wins. Before downloading this map and using it, make sure to either read the rules here on the Planet Minecraft page or in the book in the chest in the map. This map was inspired by "Hot Feet" which was created by Achievment Hunter. 

This game can have up to 9 players, 8 contestants and 1 gamemaster. The contestants fight to the death in the arena, and the gamemaster controls the spawning of blazes and fire charges. The contestants on a floor completely made of sand with wood underneath it, and above them is wood with sand above it. When the gamemaster pulls the upper and lower levers, they will release a wave of fire charges into the map, igniting the wood and causing it to burn. By burning the sand then falls, whether it be from beneath a contestants feet or from above to suffocate them. The upper floor is dark, and mobs will spawn. Some may fall through the upper floor into the arena. The gamemaster also has the ability to spawn blazes using the switch on top of the arena, which may fall into the arena. To release the contestants, the gamemaster must pull the switch in the middle. Contestants start with an infinity bow, an arrow, and a potion of invisbility. The contestant must drink the potion as soon as the game begins. Contestants are not allowed to kill each other with their fists, they must use bows to kill each other. Contestants are also not allowed to punch each other with the intent of knocking someone else off. Teaming is not recommended, since contestants cannot identify each due to everyone being invisbile. These are the rules the Contestants must follow: 

No breaking blocks
No placing blocks
No leaving the arena
No pulling levers or messing with redstone
Do not stand on any block that is stone
Do not hit other contestants (bows only)
Do not reenter starting cages (if gamemaster forgets to close them)
No hitting mobs (bows only)

Gamemaster Rules: 


No hurting or killing players
No breaking blocks
No placing blocks
No placing mobs that aren't blazes or naturally spawned
For the sake of the contestants, do not spam fire charges too much (it can get out of hand quicker than you would think, I recommend firing only one wave at the start on the top and bottom, then more as the fire starts to die out later in the game)
Close the starting cages after releasing the players

Good Luck, and Have Fun!
