The clock started the games.
The 75th Hunger Games arena was circular in shape and divided into 12 sections, each section representing an hour on a clock, then a small circular-shaped sea, and at the final bordering circle was a jungle. This arena was very small, and its circular shape tips Wiress off to the set-up of the clock mechanism. A powerful forcefield surrounded the arena like a dome.
Hunger Games arena was set up as a clock, each wedge holding a different threat. The 12 to 1 wedge consisted of the tree that would periodically be struck by lightning during the 12th hour, which proved to be a very important factor later on. The other sections of the 'clock' were made up of different horrors that would be unleashed by the hour. The 'horrors' consisted of an acid fog, blood rain, an unknown beast, a tidal wave, carnivorous monkeys, jabberjays, an unknown species of insects that emit loud clicking noises, and more which are not mentioned. The arena also has unidentified creatures, possibly mutts made by the Gamemakers roaming around.
