Run a poll on a hidden population: choose a sampling method, set the sample size, correct the bias it injects, and publish an estimate that lands on the truth.

How to play
Each poll hides a population's true value. Pick a sampling method (each has a known bias and a cost), choose how many respondents to sample on a budget, then run it. Subtract the method's known bias to recover an unbiased estimate, watch your margin of error, and publish. You score when the true value falls inside your margin.
A bigger sample shrinks the margin of error (about 1 over the square root of n) but costs more budget.
Cleaner methods carry less bias but a higher price.
Correct for the known bias before you publish.
Controls
Desktop: click a method, drag the sample-size slider, toggle the bias correction, then run and publish.
Phone & tablet: tap the method, drag the slider and use the buttons, fully touch-friendly.
Game modes
Daily: a shared seeded population.
Practice: fresh randomized polls each round.
Tips & strategy
Balance sample size against method cost, sometimes a cheap biased method plus correction beats an expensive clean one.
Always apply the known bias correction; raw cheap samples drift off the truth.
