Recently I have provided a Number Guessing Game as well, I hope that it is also beneficial for you.

The rock-paper-scissors game’s interface, as depicted in the preview, will appear similar to the final product. The opponent you’ll be playing against in this game will be the CPU. Additionally, I have included some animations to enhance the gaming experience.

          Scissors

Second, paste the following codes into your style.css file.

/* Import Google font - Poppins */
@import url("https://fonts.googleapis.com/css2?family=Poppins:wght@200;300;400;500;600;700&display=swap");
* {

}
body {
  height: 100vh;
  display: flex;
  align-items: center;
  justify-content: center;
  background: #f6f7fb;
}
::selection {
  color: #fff;
  background-color: #7d2ae8;
}
.container {
  padding: 2rem 7rem;
  border-radius: 14px;

Third, paste the following codes into your script.js file.

// Get  to DOM elements
const gameContainer = document.querySelector(".container"),
  userResult = document.querySelector(".user_result img"),
  cpuResult = document.querySelector(".cpu_result img"),
  result = document.querySelector(".result"),
  optionImages = document.querySelectorAll(".option_image");

// Loop through each option image element
optionImages.forEach((image, index) => {
  image.addEventListener("click", (e) => {
    image.classList.add("active");

    userResult.src = cpuResult.src = "images/rock.png";
    result.textContent = "Wait...";

    // Loop through each option image again
    optionImages.forEach((image2, index2) => {
      // If the current index doesn't match the clicked index
      // Remove the "active" class from the other option images
      index !== index2 && image2.classList.remove("active");
    });

    gameContainer.classList.add("start");

    // Set a timeout to delay the result calculation
    let time = setTimeout(() => {
      gameContainer.classList.remove("start");

      // Get the source of the clicked option image
      let imageSrc = e.target.querySelector("img").src;
      // Set the user image to the clicked option image
      userResult.src = imageSrc;

      // Generate a random number between 0 and 2
      let randomNumber = Math.floor(Math.random() * 3);
      // Create an array of CPU image options
      let cpuImages = ["images/rock.png", "images/paper.png", "images/scissors.png"];
      // Set the CPU image to a random option from the array
      cpuResult.src = cpuImages[randomNumber];

      // Assign a letter value to the CPU option (R for rock, P for paper, S for scissors)
      let cpuValue = ["R", "P", "S"][randomNumber];
      // Assign a letter value to the clicked option (based on index)
      let userValue = ["R", "P", "S"][index];

      // Create an object with all possible outcomes
      let outcomes = {
        RR: "Draw",
        RP: "Cpu",
        RS: "User",
        PP: "Draw",
        PR: "User",
        PS: "Cpu",
        SS: "Draw",
        SR: "Cpu",
        SP: "User",
      };

      // Look up the outcome value based on user and CPU options
      let outComeValue = outcomes[userValue + cpuValue];

      // Display the result
      result.textContent = userValue === cpuValue ? "Match Draw" : `${outComeValue} Won!!`;
    }, 2500);
  });
});

// Set the focus on input field
input.focus();

let randomNum = Math.floor(Math.random() * 100);
chance = 10;

// Listen for the click event on the check button
checkButton.addEventListener("click", () => {
  // Decrement the chance variable on every click
  chance--;
  // Get the value from the input field
  let inputValue = input.value;
  // Check if the input value is equal to the random number
  if (inputValue == randomNum) {
    // Update guessed number, disable input, check button text and color.
    [guess.textContent, input.disabled] = ["Congratulations", true];
    [checkButton.textContent, guess.style.color] = ["Replay", "#333"];
    //Check if input value is > random number and within 1-99 range.
  } else if (inputValue > randomNum && inputValue < 100) {
    // Update the guess text and remaining chances
    [guess.textContent, remainChances.textContent] = ["Your guess is high", chance];
    guess.style.color = "#333";
    //Check if input value is < random number and within 1-99 range.
  } else if (inputValue < randomNum && inputValue > 0) {
    // Update the guessed number text and remaining chances
    [guess.textContent, remainChances.textContent] = ["Your guess is low", chance];
    guess.style.color = "#333";
    // If the input value is not within the range of 1 to 99
  } else {
    // Update the guessed number text, color and remaining chances
    [guess.textContent, remainChances.textContent] = ["Your number is invalid", chance];
    guess.style.color = "#DE0611";
  }
  // Check if the chance is zero
  if (chance == 0) {
    //Update check button, disable input, and clear input value.
    // Update guessed number text and color to indicate user loss.
    [checkButton.textContent, input.disabled, inputValue] = ["Replay", true, ""];
    [guess.textContent, guess.style.color] = ["You lost the game", "#DE0611"];
  }
  if (chance < 0) {
    window.location.reload();
  }
});
