Write the prompt around a playable rule
The prompt joins a concrete question with an action and an immediate consequence. Ask for familiar examples first, then gradually mix in less familiar countries. Show all answer gates far enough ahead to make reading possible. A short explanation after the choice can reinforce the fact, but keep it to one line so it does not cover the next decision.
Original concept prompt: “Create a three-lane runner quiz about world capitals. Show a country name ahead of the player and place three capital choices on gates. Drag to the correct lane before reaching them; a correct choice gives a brief speed boost and a wrong answer costs one heart. Display the answer after each gate.” This is a recipe for an idea, not a claim that this exact game is already playable.
Play, observe and refine one thing at a time
Play a few questions and check whether you can read the country and compare all three gates before reaching them. Test a correct and incorrect lane choice to confirm the feedback and heart count match the rule. If the game feels like reflex trivia, slow the approach or add a brief decision pause. Check that questions have one unambiguous correct answer.
Tune the number of options, preview time and movement speed one at a time. If players know facts but cannot reach the lane, change steering response; if they have enough time but choices are confusing, improve answer labels. Make the post-answer fact useful and concise rather than adding an unrelated reward system.
Do not turn wrong answers into punishment without a chance to learn. Preserve a visible life count and explain the correct answer. If a question depends on contested or time-sensitive facts, choose stable material or make the context explicit. The gameplay should reward recall, not obscure wording.
Playable reference for this prompt: Capitals. Endless 3-lane runner: a country floats up and you drag left/right to run through the gate with its capital city. Right = speed boost and confetti, wrong = stumble and lose a life. Use this example to compare the proposed rules with a game you can try now.

Questions about quiz game prompt design
How much reading time does a quiz runner need?
Test the longest country and answer names at the intended speed. Provide enough approach time to read all choices before lane selection becomes irreversible.
What should happen after a wrong answer?
Reveal the correct answer and keep the consequence legible. Separate the explanation from the next question so players do not have to read both at once.
