As soon as they finished talking about the game, an orb appeared in front of each one of them. It contained the games and the rules. Everything depicted what Aurora explained. The real reason why Aurora didn't choose the Horror game previously was because of the fact that no one did. If she chose it then others need as well and if no one chose it, the game would switch in random.
They all clicked on the same chose and then a few tiles appeared around them. The other prisoners saw the tiles and choked on their breaths surprised. Who would choose a game no one ever played before? They were surprised and shocked. The other games were already hard enough but they had chances to survive. The Horror game was made in a way that saving was impossible for anyone.
