About Undo One Invention
Undo One Invention starts with a world where wheels have disappeared. Choose substitutes such as canals, walking robots, ramps, or working animals. Each fix changes four fictional service scores, so a useful transport system can still leave farming or fun behind.
How to play
- Review the ten replacement inventions and their service effects.
- Spend up to twelve tokens and install at most five fixes.
- Aim to raise mobility, deliveries, farming, and fun to at least eighty each.
- Run a day, review the result, then revise your plan if a service falls short.
Scoring and challenges
The world score is the average of its four service values. Restoring civilization requires all four services to reach eighty or more within the budget. This version contains the wheels scenario.
Questions about the game
Are the service scores real-world predictions?
