- bazzargh 12y agoYes, and when each player says a colour, they're still only right 50% of the time. But the strategy means the cases where you'd be wrong are the same cases that others would also vote incorrectly, but the cases where you're right, the others pass, so you win.

- joosters 12y agoThat's a great way of explaining it, thanks! I had read the solution but it still didn't make sense in my head how seeing the colour of unrelated hats could somehow improve the chance of you predicting your own hat colour. But as you explain, no one individual guess is better than 50%, it's just that the wrong guesses get lumped together.
