problems with an expanding css div

Question

I have tiles which expand on hover event but they are partly covered by adjacent tiles, how can i fix this?

css code snippet:

.tile {
  position: absolute;
  width: 86px;
  background-color: #000000;
  height: 86px;
  color: #fff;
  transition: 1s linear all;
  overflow: hidden;
}
.tile:hover {
  background-color: #333333;
  height: 172px;
  width: 172px;
}

here is a link to my fiddle: https://jsfiddle.net/zjcfope1/
