Spin a slot machine in specific range (max range)?

I'm newbie and try to imitate this slot machine work, example 1: https://github.com/momokang/slotmachine

Before starting to spin, I set the max value of the slot machine (ex: 500) and then I press Spin button. The result was less or maybe equal the max value (029, 358, 500); but not more than 500 (ex: 506, 789, etc...)

Is it possible to do this?

Here's the source code: https://jsfiddle.net/c07gk6yq/

Html file:

<div class="container">

            <div class="slotwrapper" id="example1">
