You are now entering the main study

The practice round is complete. From now on, please take your time on each round.

You complete {{ total_rounds }} rounds in the main study.

In every round, your job is to guess the total number of RED balls in the urn (out of 20). You are not guessing how many RED balls are left after any draws.

In some rounds, you draw the balls yourself (like in the practice). In other rounds, you see the three balls another participant drew, or you see their guess. That information is real and comes from the same urn.

Important: Each round uses a brand-new urn. It has 20 balls with between 4 and 16 RED balls.
