About HopHopWow
You have a few free minutes. The easy move is to open a feed and keep going. HopHopWow is the other option: a short game that starts fast, asks you to think a little, and actually ends.
Two ways to play
Play is logic puzzles and small challenges with one right answer. Discover asks you to predict something, then lets you explore a tiny model to see what really happens.
What we won't do
No endless feed, no auto-playing the next game, no guilt about streaks, no ads. The games are free to play and you don't need an account.
We don't claim these games raise your IQ or treat anything. They're meant to be a better few minutes.
How we check facts
Every fact card and every number in an estimation game links to the source it came from, usually NASA, NOAA, the U.S. Geological Survey, the Smithsonian, the National Park Service or a university. Before a card goes live we open that source and confirm the exact sentence it relies on, and the card shows the date we checked it.
Puzzles are original and come with a full explanation. Each one is tested by an independent solver, so there is exactly one correct answer.
We draft games with the help of AI, then check every fact against its source and playtest every puzzle before it goes live. Found a mistake? Tell us on the Support page and we'll fix it in a new version.
