Several charts claim to show the same numbers. Only one is honest, spot it, then name the deception each liar is using.

How to play
Every round presents a set of bar and pie charts built from one dataset. First click the chart that represents the data faithfully. Then, for each remaining chart, tag the specific trick it uses to mislead before you reveal the answers.
Score for finding the honest chart and again for each deception you name correctly.
Tricks include truncated baselines, misleading 3D tilt and skewed proportions.
A run spans several rounds with a running total.
Controls
Desktop: click a chart to call it honest, then use the drop-down on each liar to tag its flaw.

Game modes

Tips & strategy
Check where the y-axis starts before trusting any bar comparison.
A tilted or 3D pie almost always exaggerates the front slice.
