Guide to WhatIf Lab

Run original branching thought experiments, balance resources, explore consequences and distinguish scientific assumptions from creative speculation.

What makes WhatIf Lab different?

Strong what-if stories start by naming assumptions. Consider what a choice costs, who benefits and what new problems your solution might create.

A thoughtful way to begin

1. Read a challenge’s goal before using any controls.
2. Try one approach, then use on-screen feedback to adjust your reasoning.
3. Remember your strategy and replay challenges to improve, not to chase an imaginary leaderboard.
4. Visit the dashboard to review your locally saved discoveries.
