Frequently Asked Questions

How is the skill rating calculated?

The skill rating is the average number of points the player scored per 100 questions. The maximum possible skill rating is 200 because a correct answer is +2 points. It is not a percentage of correct answers, but it is a great measure of how accurate a player is, both in terms of answering correctly and not being very far off when he or she is wrong.

How does the point system work?

You gain two points for a correct answer. For an incorrect answer, the number of points you lose depends on how wrong you were. If you were off by one order of magnitude (i.e. answering $xxx for an $x,xxx sale) you lose two points. For being two orders of magnitude off (i.e. answering $xxx for an $xx,xxx sale) you lose four points. Answers that are three orders of magnitude off (i.e. answering $xxx for an $xxx,xxx sale) lose ten points.

Why am I seeing questions repeated?

The current method of selecting questions is to first randomly pick a price range (three, four, five, or six figures), and then randomly pick a sale within that price range. This gives an even chance of the answer being in any of the price ranges. This is done because our database does not contain an even distribution of sales. As you might expect we have many more three or four figure sales than five or six figure sales. To avoid running out of questions in the higher price ranges, we allow a sale to show up more than once. This results in duplicate questions, but you'll probably only notice it in the higher price ranges. We may change this in the future.

I've been playing as a guest but I would like to register. Will I keep my score?

Yes, when you register it takes over the guest account you were playing with, and your score and stats will move to the new account. Then we create a new guest account for you in case you want to log out and play anonymously again, this account will start from scratch though.

How do I get my picture on the leader board?

We use Gravatars for the profile picture, which is a way to link your email address to your photo. Just visit and create one for the email address that you used when you registered for the game. Guests cannot have their pictures or names on the leader board.
