Is there any way to see all of a Survey's responses?

You won't be able to see all of the responses for a given Survey, but if you use up all your guesses, you'll be able to see the top responses. You'll also be able to see how well you did compared to everyone else who has played the Survey!

Why do different Surveys have a different maximum number of guesses?

The number of guesses allowed to try and beat the game depends on the variety of Survey responses. If the game can be beaten with under 10 guesses, then you will be allowed 20 guesses to beat the game and try to get the highest score. If, however, the game requires more than 10 guesses to reach the 60% threshold, then more guesses are allowed.
