I'm coding a game to play with people who are in the same room together. As part of this game, one player is given a (uniformly) randomly chosen number between 0 and 99. The other players must guess as close as possible to this secret number based on some clues.
The challenge is that I want all players to be looking at a single screen. So I can't just display the number, since this would ruin the game. Instead, I need a way for only one person to know the number. I am not worried about players cheating.
One idea was to display something like '$2.41$^ $3.81$'. The chosen player could use a calculator to evaluate this, and the secret number might be the first two decimal places (in this case 54). If I chose this approach, I can't think of a nice way to find numbers that will give me anything from 0 to 99 uniformly.
Can you get this approach to work or think of a better strategy?
