What Is Wormillion?
Wormillion is a free daily geography game at wormillion.net. The premise is simple: name a place. The catch is that the more obscure your answer is, the deeper your worm digs. A familiar name still earns you points, but a rare, overlooked place can take you much further below the surface.
Each expedition is made up of 10 rounds, with 30 seconds per round. You can play right on the site, no account needed.
The 10-Round Core Loop
Every Wormillion round follows the same basic loop:
- Read the prompt. Some prompts are straightforward categories, like “Name a river.” Others have a twist — for example, “a river in France” means your answer has to fit both the category and the location.
- Type your answer. You have half a minute to think of a place that fits everything the prompt asks for.
- Dig. Submit your answer using the Dig control (the site hints at the ↵ key). If you’re drawing a blank, there’s also a Skip round arrow.
- Watch your depth. Your worm digs according to how obscure your answer is, and your discoveries appear on the page as you go.
Because there is more than one right answer to every prompt, the real challenge is choosing the least familiar valid answer you know.
Scoring Basics: Points and Obscurity
Wormillion compares English Wikipedia readership within each category to measure how obscure a place is. Less-read places get a higher obscurity score, and that score translates into more points and a deeper dig.
A real river round from the site shows how much one prompt can vary:
| Answer | Obscurity score | Points |
|---|---|---|
| Nile | 0.0% | 100 |
| Deseado River (Argentina) | 35.0% | 415 |
| Chalaronne (France) | 75.2% | 777 |
All three answers fit the same “Name a river” prompt. The familiar Nile earns a solid 100 points, while the less-read Deseado River earns over four times that. The Chalaronne, a much more obscure pick, reaches 777 points.
Tip: A less familiar answer takes you further. If you know an overlooked place that fits the prompt, use it.
Daily vs. Endless Dig
Wormillion offers two ways to play:
- Daily dig — This is the main daily geography puzzle. Everyone gets the same ten prompts for that day. You can finish it once, then come back tomorrow for a new expedition.
- Endless dig — A fresh ten-round expedition whenever you want another go. It’s handy for practicing new categories or playing more than once a day.
Both modes follow the same 10-round, 30-second format and use the same scoring rules.
Playing Without an Account
