Workshop › Connect Four › Step 34 of 38

Only on your turn

What we are doing

You are red, player 1. Clicks and keys should only drop a disc on your turn, and the waiting disc shows only then, in red.

```js
if (turn === 1) play(hoverCol)

  else if (turn === 1) play(hoverCol)

if (!winner && !falling && turn === 1) disc(hoverCol * CELL + CELL / 2, TOP - CELL / 2, COLORS[1])
```

What it means

• Both the click and the key play only when turn === 1.
• The waiting disc needs three things: no winner, nothing falling, and your turn. It is always red now.

Your turn

1. In pointerdown, put if (turn === 1) in front of play(hoverCol).
2. In keydown, make it else if (turn === 1) play(hoverCol).
3. In draw, change the waiting disc line as shown.
