What we are doing

On a solved board, a click or Space shuffles a new puzzle.

```js
canvas.addEventListener('pointerdown', (event) => {
  if (state === 'solved') {
    reset()
    return
  }
  // ...

  if (event.key === ' ' && state === 'solved') reset()
})
```

What it means

• A click on a solved board calls reset() and returns, so it does not also try to move a tile.
• Space is the key named ' '.

Your turn

1. In the pointerdown listener, write the if block at the very top.
2. In the keydown listener, under the arrow if block, write the Space line. Press Run.
