Wrong Number

Eight tables of real economic data. One number in each has been quietly broken — wrong sign, missing decimal, implausible jump, or a value that simply could not be true for the country listed. Spot the fabrication. Get the explanation. The skill being trained is the one good macro analysts use every day: smell-testing a number before citing it.

How it works

· Each puzzle shows a labelled series with one fabricated value.
· Click the value you think is wrong, then commit.
· The real number and a one-line diagnosis are revealed.
· Round of 8. Score is share correct. Personal best is saved locally.
