- Each day you get a 3-digit target number, which resets at 00:00 UTC.
- Ask a numerical trivia question in the text box.
- The AI replies with a single integer, which is subtracted from the target.
- Goal: reach 0 exactly, in 7 questions or fewer — otherwise you lose.
- Questions must be well-known trivia; invalid ones return: "Please try another question."
- The AI only knows data up to 2024, so newer facts may be wrong.
- Examples: "How many days in a year?", "How many countries are there?"
- No numbers (digits or words) allowed, to prevent cheats like "What is 653 + 1?"
- If the total goes negative, you go bust and the game ends immediately.
- You get one game per day; return after the countdown for the next target.
- Tip: Press Enter to submit a question.
