A small puzzle.
Your own project.

Six reproducible puzzle generators for browser games and learning demos. Get a question, render it your way, and check the answer locally.

ONE GENERATOR, TWO FUNCTIONS

const question = makeQuestion(
  'math', 0, 'my-demo', 2
);

// Render the prompt and options.
// Collect a selected option index.
const correct = evaluateAnswer(
  question, selectedIndex
);

The starter includes the library and a small working interface. Change the rendering section to make it yours.

Reproduce a question

Keep the version, seed, index and difficulty to replay the same output. Useful for sharing a bug or testing your interface.

Use the pieces you need

Math, number sequences, words, memory, color and odd-one-out tasks. Plain question objects work with your own interface.

Inspect and adapt

Readable JavaScript, answer explanations, TypeScript declarations and an MIT license. The runtime makes no network requests.
