Levels

What we are doing

Every 10 lines is a new level, and points are multiplied by the level. The level is worked out from lines each time we need it.

```js
function level() {
  return Math.floor(lines / 10) + 1
}

  score += POINTS[cleared] * level()

  ctx.fillText('Level', panel, 300)
  ctx.fillText(String(level()), panel, 322)
```

What it means

• lines / 10 rounded down with Math.floor, plus 1: 0–9 lines is level 1, 10–19 level 2, and so on.
• clearLines multiplies the points by the level (it uses level() before adding the new lines).
• The panel shows the level under Lines.

Your turn

1. Write level above function clearLines() {.
2. In clearLines, multiply the points by level().
3. In draw, under the lines number, write the two Level lines.
