[4PC Variant]: Custom Starting Position

Here is an idea called "Ultimate Conflict." It consists of every piece in the game and is played like a normal game where you have to get checkmated to get out. Hopefully this will get made! Here is the code for my game.

what are the rules and time control?
Time is 1|15D and rules are you are alive till you are checkmated. It is FFA, and that is pretty much all

Rules of the game, example: promotion rank, DeadWall, KOTH, Solo or Teams ...

NAME => Knight's Fight

bsrti, I added King of the cave as a casual game.
omatamix, I added Mini 4PC as a rated game.
Kim517, I added Nightmare in fairyland as a Tournament in the Test Server
ywq915, could you play some games that are purely human games, without the random bots mixed in with other humans?
BeigeBasketball, have you played any games from your position?
What's a test server?

Info-text:
Welcome to the Minotaur's Labyrinth! Here, you should try to avoid the blue queen (minotaur): it cannot be captured in any way. Avoid getting checked by it! Each player has only 9 checks, if you are checked 9 times, you lose. Try to get your king to the center of the board to win. Good luck!
Additional info:
The last player standing should be granted 20 points, if possible.

@bsrti nice! i was always thinking of games like that.
I invented the immune zombies because well the bad guys kept getting eaten to easily in my experiments . But they are so powerful now. I was using Knights mostly as immune zombies in such games.
Actually, Minotaur Labyrinth is quite popular: I get needed 2 players less than in a minute. It would be interesting if there were rated games and tournaments with this mode.
