1. First of all, create the HTML structure as follows:

<div class="tabel ctr">
    <div class="board"><span id="col-0"></span><span id="col-1"></span><span id="col-2"></span><span id="col-3"></span><span id="col-4"></span><span id="col-5"></span><span id="col-6"></span><span id="col-7"></span><span id="col-8"></span></div>
    <button id="reset">Reset</button>
</div>

2. After that, add the following CSS styles to your project:

@import url("https://fonts.googleapis.com/css?family=Press+Start+2P&display=swap");
* {
  
  user-select: none;
}

.ctr {
  font-family: "Press Start 2P", cursive;
  display: flex;
  justify-content: center;
  align-items: center;
}

.tabel {
  width: 480px;
  height: 480px;
  margin: 10px auto;
  background: #76AFD6;
  border-radius: 100%;
  border: 1px solid #0D152B;
  box-shadow: -2px 20px 0 -3px #4283C4, -20px 20px #0D152B;
  flex-direction: column;
}

.board {
  width: 369.2307692308px;
  height: 369.2307692308px;
  background: #D3E2EA;
  border-radius: 20px;
  border: 1px solid #0D152B;
  box-shadow: -10px 5px 0px -2px #192852;
  display: grid;
  grid-template-rows: repeat(3, 1fr);
  grid-template-columns: repeat(3, 1fr);
  grid-gap: 8px;
  padding: 12px;
}

.board > span {
  background: #76AFD6;
  color: #fff;
  font-size: 4em;
  padding-left: 9px;
  padding-top: 6px;
  text-align: center;
  border: 2px solid #0D152B;
  border-radius: 5px;
  cursor: pointer;
  transition: all 0.2s ease;
  box-shadow: -1.2px 2px 0px 0px #141D4C;
}
.board > span:hover {
  background: #6aa8d2;
}
.board > span:active {
  box-shadow: -1.2px 7.4px 0px -2.5px #141D4C;
}

#reset {
  margin-top: 14px;
  color: #fff;
}

.win {
  background: #55efc4 !important;
}

3. Finally, add the following JavaScript code and done.

'use strict'

const _ = document,
          cols = Array.from(_.querySelectorAll('.board > span')),
					reset = _.querySelector('#reset')
let cur = true
let arr = new Array(9).fill(null)
const wins = [
  [0, 1, 2],
  [3, 4, 5],
  [6, 7, 8],
  [0, 3, 6],
  [1, 4, 7],
  [2, 5, 8],
  [0, 4, 8],
  [2, 4, 6]
]
function event(can) {
	reset.addEventListener('click', fnreset)
  for(let col of cols)
    if(can)
      col.addEventListener('click', play)
    else
      col.removeEventListener('click', play)
}
event(true)
function play(e) {
  const __ = e.target
  if(!__.innerHTML){
    cur = !cur
    __.innerHTML = cur ? '<h1 name="O">O</h1>' :  '<h1 name="X">X</h1>'
    move(parseInt(__.id.split(/\D+/g)[1]), __.childNodes[0].getAttribute('name'))
  }
}

function move(ind, sign) {
  arr[ind] = sign
  console.log(arr)

  for (let i = 0; i < wins.length; i++) {
     let [a, b, c] = wins[i] 
      if(cmp(arr[a], arr[b], arr[c])){
        console.log(sign, ' wins')
        event(false)
        cols[a].classList.add('win')
        cols[b].classList.add('win')
        cols[c].classList.add('win')
      }
  }
}
function cmp(a, b, c) {
  if(a && b && c)
    return (a === b) && (a === c) && (b === c)
}

function fnreset() {
    for(let col of cols){
      col.classList.remove('win')
      col.innerHTML = ''
    }
    arr = new Array(9).fill(null)
    event(true)
}
