Footbillion Unlimited is a small independent project: a football quiz where the obvious answer is worth the least and the forgotten one is worth the most.
Why we built it
Rare-answer football quizzes are a lot of fun, but most of them give you one round per day. We wanted a version you can keep playing: seven prompts per round, as many rounds as you like, across six topic packs.
How the questions are made
Every prompt is a closed list of correct answers with a fixed date range, for example "a club that won the FA Cup between 2000 and 2024". Fixing the range means a prompt stays correct when a new season finishes. Each list is checked against published competition records before it goes into the game.
How rarity works
Answer values come from what real players type. The game counts, anonymously and per prompt, how many players gave each answer, and turns those counts into transfer values between €10m and €145m. We never store names, emails or any other personal details for this.
Found a mistake?
If you think an answer is missing or wrong, tell us in the comments on the home page or through the contact page. Please include the prompt and the answer, and we'll check it against the records.
