Does It Really Work?
Does It Really Work? is a short, replayable puzzle game that trains causal intuition. Each level presents a believable headline and a convincing chart, and you decide whether it shows a real cause-effect link or a confounded correlation. On reveal you drag a stratification slider to split the data by the hidden confounder and watch the aggregate trend reverse in front of you. Finish the run to get a score, a percentile, a per-level review, and a shareable result card.
