Add a ``tool`` variable to store a random number computed with ``||math:pick random||``. Add a ``hand`` variable
and place the ``||variables:set hand to||`` block in the shake event.
When you shake the @boardname@, it should pick a random number from `0` to `2` ![A animation that shows how to create a variable](/static/mb/projects/rock-paper-scissors/newvar.gif)
and store it in the variable named ``tool``.
## Step 3 @fullscreen
Add a ``||math:pick random||`` block to pick a random number from `1` to `3` and
store it in the variable named ``hand``.

let tool = 0; let hand = 0;
input.onGesture(Gesture.Shake, () => { input.onGesture(Gesture.Shake, () => {
tool = Math.randomRange(0, 2) hand = Math.randomRange(1, 3)
}) })
``` ```
In a later step, each of the possible numbers (`0`, `1`, or `2`) is matched to its own picture. The picture is shown on the LEDs when its matching number is picked.
