We need to set up some input buttons to use the game logic. These input buttons are set up in HTML. We will put the following number controls in HTML, inside the #game section and after <canvas>:

<div id="control-box">

  <a class="control" data-value="2" href="#">2</a>
  ...
  <a class="control" data-value="11" href="#">11</a>
  <a class="control" data-value="12" href="#">12</a>
</div>

#control-box {
  width: 100%;
  overflow: auto;
  position: absolute;
  bottom: 0;
}

.control ...
