EDIT → RUN → TRY YOUR PAGE
Make one puzzle your own.
Change this working example directly in your browser. The library generates and checks the question; you control the page.
- Under HTML, change the heading or the seed input's
my-first-puzzlevalue. Under JavaScript, try changing how the answer feedback is displayed. - Choose Run preview and answer a question.
- Download your page or share what worked or blocked you.
Your edits stay in this tab; they are not saved or sent anywhere. Download before closing. The preview blocks network requests and runs separately from the editor. This is a maintainer example, not evidence of outside adoption.
Preparing the example…
JavaScript · generation, rendering and checking
HTML · headings, controls and page content
CSS · colors, layout and type
Use ordinary browser code and the included makeQuestion and evaluateAnswer functions. The engine and MIT notice are included in the downloaded page. Switching to another game needs a renderer for that game's question shape.
