Ring the Bell
From Halopedia, the Halo wiki
Ring the Bell was the game that John-117, Kelly-087, and Samuel-034 played on their first day of training in order to earn their dinner. The object of the game was to reach the top of a tower, have each member of your team ring the bell, and then cross the finish line with your team. Also note that the first time the game was played by the trainees, John-117 got greedy and sped ahead and finished first, therefore slowing down his teamates and causing all of them to lose, and they had to go without dinner.
Trivia
- The bell used for this game was also used for a similar game in which John-117 was to make his way across an obstacle course on his first day with Cortana.
