The jailer is going to ask the color of each prisoner’s hat starting from the last prisoner in queue. If a prisoner says the correct color, they are saved. What rule can the prisoners make to guarantee 99 would be saved if they are allowed to discuss a strategy before the jailer starts asking colors of their hats?

If they’re allowed to discuss a strategy then they could do sth like: scream the color if the color you’re mentioning is the same color as the hat in front of you, say it normally if it’s different. Saves 99.5 on avg :)

Assuming they can’t rearrange and have to stay in the same line formation
