Game mechanicsKnob to turn
For questions whose answer is a number. Players dial in the value they think is right.
Describe your game: the assistant builds it, you fine-tune it.
How it works
The knob is built for numeric answers: a percentage, a distance, a temperature, a lead time. Players set the value on a scale you define.
Estimating a number makes people think about its order of magnitude, and the gap from the right answer often sticks better than an explanation. You decide whether you want the exact value or a range. The AI assistant can build this step from a description.
For the player
- 1Players see the value in large type with its unit, and the scale from lowest to highest.
- 2They drag the control, or press minus and plus to move one notch. Holding a button keeps the value moving.
- 3They submit. If they're outside the accepted range, they can try again as long as they have tries left.
What you set
- Set the scale: minimum, maximum and step size (1, 5, 0.5...).
- Add a unit shown after the number, like %, °F, mi or lb.
- Enter the right answer and the accepted range. To require the exact value, give both ends the same number.
- Set tries, points, the timer, hints, and whether the correct answer appears after a miss.

Frequently asked questions
How do I add a question with a numeric answer to a quiz?
Add a Knob step in the Ludiz editor, set the scale and unit, then the right answer and the accepted margin.
Can I accept an approximate answer?
Yes. Set a range, for example 40 to 60, and any value inside it counts as correct.
How is it different from the slider?
The knob asks for a single value. The slider asks for a range, with a low end and a high end.
