Number Guessing Game

Mystery Number Guessing Game Project!

Table of Contents

    We always say to our friends, “Let’s guess the number.” You’ve probably heard the answers: “No, it’s bigger. No, it’s smaller. Wow, how did you know?” Wouldn’t you like to do just that with PicoBricks? We invite you to a journey full of mathematics and intelligence! Today we open the door to an exciting project: the number guessing game project. 

    This project is a fun experience designed to test your math skills, improve problem-solving skills, and hone your mental abilities.

    The guess the number game is a fun and interactive coding project that challenges players to guess a random number within a specified range. This number guessing game project not only sharpens your programming skills but also offers an entertaining experience for players as they attempt to guess the correct number. Whether you’re a beginner looking to learn coding or an enthusiast seeking an engaging game development project, Guess The Number Game is a great choice to explore and enjoy.

    Remember, you will learn much more than just to guess the number in this project…

    Guess The Number!

    Details and Algorithm

    Press the “Start” button to start the number guessing game. To update your forecast, follow the steps below. If the player presses the up arrow key from remote (if the picobrick estimate is less than the number the player selected), the estimated range is halved again and that value is added to the current picobrick estimate. 

    If the player presses the down arrow key from remote (if the picobrick estimate is greater than the number selected by the player), the estimated range is halved again and that value is subtracted from the current picobricks estimate. When the player presses the “OK” button from remote, the  number guessing  game ends and PicoBricks celebrates. This means that the number chosen by the player was guessed correctly!

    What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
