Workshop › Puzzle Bobble-style Bubble Shooter › Step 29 of 31

Best score

What we are doing

When a game ends with a new record, it is saved in localStorage and shown on the right of the top bar.

```js
let best = Number(localStorage.getItem('bubbles-best')) || 0

  if (state !== 'playing' && score > best) {
    best = score
    localStorage.setItem('bubbles-best', best)
  }

  ctx.textAlign = 'right'
  ctx.fillText('Best ' + best, canvas.width - 10, 21)
```

What it means

• The record is read once when the page opens (0 the first time).
• Only when the game has just ended and the score beats it, it is updated and saved.
• textAlign = 'right' makes the text end 10 pixels from the right edge.

Your turn

1. Under let state, write best.
2. At the end of attach, save the record.
3. In draw, under the Score line, write the two Best lines.
