The Gamemakers design and control the Hunger Games. They design the arena and the outfits, as well as the animals in the arena and the scenery of the arena. They also keep track of the number of deaths that happen in the arena. From the tiniest detail to the biggest bloodbath, the Gamemakers are in charge of entertaining the Capitol to the fullest. A dry and boring Hunger Games means that the head Gamemakers' lives are in peril. A bloody and fantastic Games that keeps the crowd on the edge of their seats brings the Gamemakers fame and fortune. Although the Gamemakers are in charge of the Games, President Snow's opinion is what matters most. Seneca Crane used to be the head Gamemaker, but when he let Katniss Everdeen and Peeta Mellark both survive the 74th Hunger Games, he was killed on orders of President Snow for allowing both Katniss and Peeta to live. Plutarch Heavensbee took his place as the new Head Gamemaker, and used his position to assist in the rebellion and break tributes out of the arena.
The Gamemakers' job is to make the Hunger Games as spectacular, bloody, frightening and entertaining as possible. When the Head Gamemaker feels that the Games are becoming boring, they will introduce some new element such as a forest fire or tsunami or announce a feast to excite the audience to drive the tributes closer together and kill some of them off. They control everything that happens in the arena. The Gamemakers are responsible for the announcements made in the arena by Claudius Templesmith and for sounding the cannons upon a Tribute's death. They also unleash lab-grown muttations into the arena to add another obstacle to survival. These have included carnivourous squirrels, monsterous ape-like creatures and giant wolf-mutts which aside from being extremely dangerous, have a profound psychological effect on the Tributes. They can also alter day and night, where the water flows, temperature, and many more enviromental things. The Gamemakers also operate the extensive survaillence system in the arena, ensuring the tributes are being watched constantly. In the case that the Gamemakers dislike a certain tribute they can easily kill him/her off, as seen with Titus.
