MYSTERY DOOR

ONCE everyone ate, the tables around the ballroom disappeared.  Then the King stood up once again.  

"Now that we've all eaten and filled our stomachs, it's time for this year's entertainment to begin," he said.  "This year's theme is unlike what we've had these past years.  I hope all of you could enjoy what I've prepared.  And in return, you have to do your best to entertain me as well." He smiled gently at them.  "Okay?"

He snapped his fingers and five doors in different colors appeared in front of everyone.  From left to right, the colors were; red, purple, green, yellow, and blue.

And then after that, a maze appeared that occupied the whole ballroom.  It separated each player from one another.
